Abstract

Background

Gymnema sylvestre is an ethno-pharmacologically important medicinal plant used in many polyherbal formulations for its potential health benefits. Silver nanoparticles (SNPs) were biofunctionalized using aqueous leaf extracts of G. sylvestre. The anticancer properties of the bioactive compounds and the biofunctionalized SNPs were compared using the HT29 human adenoma colon cancer cell line.

Methods

The preliminary phytochemical screening for bioactive compounds from aqueous extracts revealed the presence of alkaloids, triterpenes, flavonoids, steroids, and saponins. Biofunctionalized SNPs were synthesized using silver nitrate and characterized by ultraviolet–visible spectroscopy, scanning electron microscopy, energy-dispersive X-ray analysis, Fourier transform infrared spectroscopy, and X-ray diffraction for size and shape. The characterized biofunctionalized G. sylvestre were tested for its in vitro anticancer activity against HT29 human colon adenocarcinoma cells.

Results

The biofunctionlized G. sylvestre SNPs showed the surface plasmon resonance band at 430 nm. The scanning electron microscopy images showed the presence of spherical nanoparticles of various sizes, which were further determined using the Scherrer equation. In vitro cytotoxic activity of the biofunctionalized green-synthesized SNPs (GSNPs) indicated that the sensitivity of HT29 human colon adenocarcinoma cells for cytotoxic drugs is higher than that of Vero cell line for the same cytotoxic agents and also higher than the bioactive compound of the aqueous extract.

Conclusion

Our results show that the anticancer properties of the bioactive compounds of G. sylvestre can be enhanced through biofunctionalizing the SNPs using the bioactive compounds present in the plant extract without compromising their medicinal properties.

<title>Background</title>
<p>
<italic>Gymnema sylvestre</italic>
is an ethno-pharmacologically important medicinal plant used in many polyherbal formulations for its potential health benefits. Silver nanoparticles (SNPs) were biofunctionalized using aqueous leaf extracts of
<italic>G. sylvestre</italic>
. The anticancer properties of the bioactive compounds and the biofunctionalized SNPs were compared using the HT29 human adenoma colon cancer cell line.</p>
</sec>
<sec>
<title>Methods</title>
<p>The preliminary phytochemical screening for bioactive compounds from aqueous extracts revealed the presence of alkaloids, triterpenes, flavonoids, steroids, and saponins. Biofunctionalized SNPs were synthesized using silver nitrate and characterized by ultraviolet–visible spectroscopy, scanning electron microscopy, energy-dispersive X-ray analysis, Fourier transform infrared spectroscopy, and X-ray diffraction for size and shape. The characterized biofunctionalized
<italic>G. sylvestre</italic>
were tested for its in vitro anticancer activity against HT29 human colon adenocarcinoma cells.</p>
</sec>
<sec>
<title>Results</title>
<p>The biofunctionlized
<italic>G. sylvestre</italic>
SNPs showed the surface plasmon resonance band at 430 nm. The scanning electron microscopy images showed the presence of spherical nanoparticles of various sizes, which were further determined using the Scherrer equation. In vitro cytotoxic activity of the biofunctionalized green-synthesized SNPs (GSNPs) indicated that the sensitivity of HT29 human colon adenocarcinoma cells for cytotoxic drugs is higher than that of Vero cell line for the same cytotoxic agents and also higher than the bioactive compound of the aqueous extract.</p>
</sec>
<sec>
<title>Conclusion</title>
<p>Our results show that the anticancer properties of the bioactive compounds of
<italic>G. sylvestre</italic>
can be enhanced through biofunctionalizing the SNPs using the bioactive compounds present in the plant extract without compromising their medicinal properties.</p>

<title>Introduction</title>
<p>For treatment of various diseases, bioactive components from medicinal plants that are similar to chemical compounds are used.
<xref rid="b1-ijn-10-031" ref-type="bibr">1</xref>
In recent years, the use of ethno-botanical information in medicinal plant research has gained considerable attention in some segments of the scientific community.
<xref rid="b2-ijn-10-031" ref-type="bibr">2</xref>
In one of the ethno-botanical surveys of medicinal plants commonly used by the Kani tribals in Tirunelveli hills of the Western Ghats in Tamil Nadu, India, it was revealed that
<italic>Gymneme sylvestre</italic>
is the most important species based on its use.
<xref rid="b2-ijn-10-031" ref-type="bibr">2</xref>
The use of plant parts and isolated phytochemicals for the prevention and treatment of various health ailments has been in practice for many decades.

antiulcer, anti-stress, and antiallergic activity.
<xref rid="b13-ijn-10-031" ref-type="bibr">13</xref>
</p>
<p>The presence of flavonoids, saponins, anthraquinones, quercitol, and other alkaloid have been reported in the flowers, leaves, and fruits of
<italic>G. sylvestre</italic>
.
<xref rid="b14-ijn-10-031" ref-type="bibr">14</xref>
The presence of other therapeutic agents, such as gymnemagenin, gymnemic acids, gymnemanol, and β-amyrin-related glycosides, which play a key role in therapeutic applications, have also been reported. The focus of the present work is to assess the potential therapeutic medicinal value of this herb and to understand/enhance the mechanistic action of their bioactive components.
<xref rid="b14-ijn-10-031" ref-type="bibr">14</xref>
</p>
<p>
<italic>G. sylvestre</italic>
contains triterpenes, saponins, and gymnemic acids belonging to the oleane and dammarene classes.
<xref rid="b15-ijn-10-031" ref-type="bibr">15</xref>
,
<xref rid="b16-ijn-10-031" ref-type="bibr">16</xref>
The plant extract has also tested positive for alkaloids, acidic glycosides, and anthraquinone derivatives. Oleanane saponins are gymnemic acids and gymnema saponins, while dammarene saponins are gymnemasides.</p>
<p>As reported by Thakur et al
<xref rid="b14-ijn-10-031" ref-type="bibr">14</xref>
the aqueous extracts of the
<italic>G. sylvestre</italic>
leaves showed the presence of gymnemic acids Ι–VΙ, while the saponin fraction of the leaves tested positive for the presence of gymnemic acids XV–XVIII. The gymnemic acid derivative of gymnemagenin was elucidated from the fraction VIII–XII, which is responsible for the antidiabetic activity, and the fraction VIII stimulates the pancreas for insulin secretion. The novel D-glucoside structure with anti-sweet principle is present in the I–V saponin fraction. The presence of pentatriacontane, α- and β-chlorophylls, phytin, resins, D-quercitol, tartaric acid, formic acid, butyric acid, lupeol, and stigmasterol has been reported as other plant constituents of
<italic>G. sylvestre</italic>
,
<xref rid="b14-ijn-10-031" ref-type="bibr">14</xref>
while the extract has also been tested positive for alkaloids.

</p>
<p>Sharma et al have reported the antioxidant activity of oleane saponins from
<italic>G. sylvestre</italic>
plant extract and determined the IC
<sub>50</sub>
values for 2,2-diphenylpicrylhydrazyl (DPPH) scavenging, superoxide radical scavenging, inhibition of in vitro lipid peroxidation, and protein carbonyl formation as 238 μg/mL, 140 μg/mL, 99 μg/mL, and 28 μg/mL, respectively, which may be due to the presence of flavonoids, phenols, tannins, and triterpenoids.
<xref rid="b18-ijn-10-031" ref-type="bibr">18</xref>
The enhanced radiation (8 Gy)-induced augmentation of lipid peroxidation and depletion of glutathione and protein in mouse brain were reported by Sharma et al
<xref rid="b18-ijn-10-031" ref-type="bibr">18</xref>
using multiherbal ayurvedic formulations containing extracts of
<italic>G. sylvestre</italic>
, such as “Hyponidd” and “Dihar”. They also demonstrated the antioxidant activity by increasing the levels of superoxide dismutase, glutathione, and catalase in rats through in vivo studies.
<xref rid="b19-ijn-10-031" ref-type="bibr">19</xref>
</p>
<p>Kang et al
<xref rid="b20-ijn-10-031" ref-type="bibr">20</xref>
proved the role of antioxidants from
<italic>G. sylvestre</italic>
in diabetic rats using ethanolic extracts. Using several antioxidant assays, eg, thiobarbituric acid assay with slight modifications, egg yolk lecithin or 2-deoxyribose (associated with lipid peroxidation) assay, superoxide dismutase-like activity assay, and 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) assay.</p>
<p>The potent anticancer activity of
<italic>G. sylvestre</italic>
against the human lung adenocarcinoma cell lines (A549) and human breast carcinoma cell lines (MCF7) using alcoholic extracts of the herb has been reported by Srikant et al.
<xref rid="b21-ijn-10-031" ref-type="bibr">21</xref>
Also, Amaki et al
<xref rid="b22-ijn-10-031" ref-type="bibr">22</xref>
reported the inhibition of the breast cancer resistance protein using the alcoholic extract of
<italic>G. sylvestre</italic>
.</p>
<p>Many plant-derived saponins, eg, ginsenosides, soyasaponins, and saikosaponins, have been found to exhibit significant anticancer activity. The anticancer activity of gymnemagenol on HeLa cancer cell lines in in vitro conditions was determined by the MTT cell proliferation assay for cytotoxic activity of saponins. Using 5 μg/mL, 15 μg/mL, 25 μg/mL, and 50 μg/mL concentrations of gymnemagenol, the IC
<sub>50</sub>
value was found to be 37 μg/mL after 96 hours. The isolated bioactive constituent, gymnemagenol, showed a high degree of inhibition to HeLa cancer cell line proliferation, and saponins were not found to be toxic to the growth of normal cells under in vitro conditions.
<xref rid="b23-ijn-10-031" ref-type="bibr">23</xref>
</p>
<p>Already many researchers have reported that the leaves of
<italic>G. sylvestre</italic>
lower blood sugar, stimulate the heart, uterus, and circulatory systems, and exhibit anti-sweet and hepatoprotective activities.

Administration of
<italic>G. sylvestre</italic>
extract to diabetic rats increased superoxide dismutase activity and decreased lipid peroxide by either directly scavenging the reactive oxygen species, due to the presence of various antioxidant compounds, or by increasing the synthesis of antioxidant molecules (albumin and uric acid).

<p>Therefore, in this study, an attempt was made to synthesize the silver nanoparticles (SNPs) from aqueous extracts of the
<italic>G. sylvestre</italic>
leaves. These green-synthesized SNPs (GSNPs) of
<italic>G. sylvestre</italic>
were examined by ultraviolet–visible (UV–vis) spectroscopy, scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDAX), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) analysis for studying their size and shape. The synthesized and well-characterized nanoparticles (NPs) were tested for their cytotoxicity effect. Our findings clearly demonstrate that it is indeed possible to have a much greener way to synthesize SNPs without compromising their antibacterial properties and thus plant extracts may prove to be a good alternative to obtain such NPs with improved antibacterial and antiviral properties for diabetic wound healing applications. Goix et al
<xref rid="b33-ijn-10-031" ref-type="bibr">33</xref>
and Boholm and Arvidsson
<xref rid="b34-ijn-10-031" ref-type="bibr">34</xref>
have pointed out that silver is either beneficial or harmful in relation to four main values: the environment, health, sewage treatment, and product effectiveness. As reported by Barua et al
<xref rid="b35-ijn-10-031" ref-type="bibr">35</xref>
poly(ethylene glycol)-stabilized colloidal SNPs showed the nonhazardous anticancer and antibacterial properties. Jin et al
<xref rid="b36-ijn-10-031" ref-type="bibr">36</xref>
have reported the therapeutic applications of plant-extract-based scaffolds for wound healing and skin reconstitution studies.</p>

<title>Preparation of aqueous extract</title>
<p>The leaves of
<italic>G. sylvestre</italic>
were washed with distilled water to remove the dirt and further washed with mild soap solution and rinsed thrice with distilled water. The leaves were blot-dried with tissue paper and shade dried at room temperature for 2 weeks. After complete drying, the leaves were cut into small pieces and powdered in a mixer and sieved using a 20-μm mesh sieve to get a uniform size range for further studies. Twenty grams of the sieved leaf powder was added to 100 mL of sterile distilled water in a 500-mL Erlenmeyer flask and boiled for 5 minutes. The flask was kept under continuous dark conditions at 30°C in a shaker. The extract was filtered and stored in an airtight container and protected from sunlight for further use.

solution in a 250-mL Erlenmeyer flask and incubated in a rotary shaker at 150 rpm in dark. The synthesis of NPs was confirmed spectrophotometrically at every 30-minute interval till no reduction was observed. The reduction was observed by the color change in the colloidal solution, which confirmed the formation of SNPs.

<p>The preliminary phytochemical screening of aqueous extracts of

revealed the presence of alkaloids, phenols, flavonoids, sterols, tannins, and triterpenes (
<xref ref-type="table" rid="t1-ijn-10-031">Table 1</xref>
). As shown in
<xref ref-type="table" rid="t2-ijn-10-031">Table 2</xref>
, 125.62±26.84 μg/g of total flavonoids, 285.23±1.11 μg/g of total phenols, and 111.53±15.13 μg/g of tannin were present in the aqueous extract of

<title>Characterization of biofunctionalized SNPs</title>
<p>The color change observed in the aqueous silver nitrate solution showed that the SNPs were formed rapidly within 30 minutes of incubation of the plant extract with aqueous AgNO
<sub>3</sub>
solution. The colorless solution changed to ruby red, confirming the formation of SNPs (
<xref ref-type="fig" rid="f1-ijn-10-031">Figure 1</xref>
). The intensity of the red color increased with time because of the excited surface plasmon resonance effect and reduced AgNO
<sub>3</sub>
. The control aqueous AgNO
<sub>3</sub>
solution (without leaf extract) showed no change of color with time and was taken as the blank reference.</p>
<p>UV–vis spectrometry is a reliable and reproducible technique that can be used to accurately characterize the metal NPs though it does not provide direct information regarding the particle sizes. The surface plasmon bands (absorbance spectra) are influenced by the size and shape of the NPs produced, along with the dielectric constant of the surrounding media.</p>
<p>
<xref ref-type="fig" rid="f2-ijn-10-031">Figure 2</xref>
shows the time-dependent intensity of the absorption band, which reached its maximum peak at 12 hours, after which no further change in the spectrum was observed indicating that the precursors had been consumed. Initially, the UV–vis spectrum did not show evidence of any absorption in the region 350–600 nm, but after the addition of extract a distinct band was observed at 432 nm.</p>
<p>When silver nitrate was added to the aqueous plant extract of
<italic>G. sylvestre</italic>
, it was reduced to SNPs by the aldehyde group present in the flavonoids (125.6 μg/g), which was further oxidized to the carboxyl group. Also, the carboxyl groups of the phenols from the
<italic>G. sylvestre</italic>
extract (285.23 μg/g) acted as a surfactant to attach the major phytochemicals from the plant extract to the surface of the SNPs. Our previous study on the synthesis of SNPs using aqueous extracts of

and

<xref rid="b50-ijn-10-031" ref-type="bibr">50</xref>
showed that the color of the reaction mixture during the formation of GSNPs changed to ruby red color from colorless/straw color. Our results are also comparable with the other available reports for plant-extract-mediated synthesis of SNPs.</p>
<p>From
<xref ref-type="fig" rid="f3-ijn-10-031">Figure 3</xref>
, it is clear that the synthesized SNPs were approximately spherical and of different sizes. The SEM images in the figure clearly indicated a thin layer of phytochemicals from the plant extract covering the synthesized SNPs. Mostly the total phenolic content, flavonoids, and tannins were responsible for the bioreduction of the SNPs. In this green synthesis, the phytochemicals from the plant extract acted as a surfactant to prevent the aggregation of the synthesized SNPs. The SEM images of our earlier research had revealed that this biologically eco-friendly synthesis of NPs utilizing the leaf extracts of
<italic>M. edule</italic>

and
<italic>M. umbellatum</italic>
<xref rid="b47-ijn-10-031" ref-type="bibr">47</xref>
showed no aggregation due to the biomolecules from the plant extract. And the mechanism behind this particle formation with no aggregation may be the spontaneous nucleation and isotropic growth of NPs along with the plant extract. As these chains grow in diameter with increasing silver deposition, spherical particles break off from these structures forming nanospherical particles which can be typically observed from this synthesis.

<xref ref-type="fig" rid="f4-ijn-10-031">Figure 4</xref>
clearly shows the strong signals from silver atoms along with the weaker signals from carbon and oxygen present from biomolecules of the plant extract. The elemental silver peak at 2–4 keV, which is the major emission peak specified for metallic silver, with minor peaks of C and O were also seen due to the capping of Ag NPs by the biomolecules of
<italic>G. sylvestre</italic>
leaf extract, and the absence of other peaks evidenced the purity of the Ag NPs.</p>
<p>FTIR analysis in
<xref ref-type="fig" rid="f5-ijn-10-031">Figure 5</xref>
shows that the SNPs produced by
<italic>G. sylvestre</italic>
extract were coated by phytocompounds and secondary metabolites such as saponins, terpenoids, and gymnemagenin derivative of gymnemic acid containing the functional groups of amines, aldehydes, carboxylic acids, and alcohols.</p>
<p>The presence of the amide linkages seen in
<xref ref-type="fig" rid="f5-ijn-10-031">Figure 5</xref>
suggests that the different functional groups of the proteins present in the plant extracts might be capping the NPs and playing an important role in the stabilization of the green NPs formed. The band at 1,443 cm
<sup>−1</sup>
was assigned to the methylene scissoring vibrations of proteins, and the bands located at 1,318 cm
<sup>−1</sup>
and 1,089 cm
<sup>−1</sup>
are due to the C–N stretching vibration of aromatic and aliphatic amines, respectively, which agrees with earlier reports of Suman et al.
<xref rid="b52-ijn-10-031" ref-type="bibr">52</xref>
</p>
<p>The positions of these bands were comparable to those reported for phytochemicals reported in the
<italic>G. sylvestre</italic>
extract as total phenols, flavonoids, and tannins (
<xref ref-type="table" rid="t2-ijn-10-031">Table 2</xref>
). Thus, we can confirm that the nanocapping of the phytochemicals from the
<italic>G. sylvestre</italic>
extract is responsible for the reduction and subsequent stabilization of the SNPs. The absorption bands that appear in the IR spectrum of the aqueous extract could also be seen in the IR spectra of phyto-capped Ag NPs, confirming the role of the phyto constituents (mostly gymnemic acid) in protecting the Ag NPs from aggregation.</p>
<p>Also, during our repeated experiments there were no batch-to-batch variations in size, regardless of the isotopic composition, and the particles diameters of the SNPs formed were known to a high degree of accuracy. A detailed study on the large-scale synthesis and elemental composition on the synthesized NPs can be carried out using inductively coupled plasma mass spectrometry to obtain reproducible compositions in every batch. In future, the elemental analysis can be carried out as described earlier by other researchers.

<p>XRD analysis of NPs represented in
<xref ref-type="fig" rid="f6-ijn-10-031">Figure 6</xref>
shows several size-dependent features leading to irregular peak position, height, and width. XRD was mainly carried out to study the crystalline nature of the green-synthesized
<italic>G. sylvestre</italic>
SNPs. From the figure, the GSNPs are seen to exhibit monocrystallinity. The XRD peaks at 38.2°, 44.5°, 64.7°, and 77.7° can be indexed to the [111], [200], [220], and [311] planes, indicating that the SNPs are highly crystalline. Similar results were reported for

<title>In vitro anticancer activity</title>
<p>From
<xref ref-type="fig" rid="f7-ijn-10-031">Figure 7</xref>
, it can be observed that, as the concentration of the GSNPs increased, the percentage of viable cells decreased in the cytotoxicity studies by MTT assay. The GSNPs were taken up by mammalian cells through different mechanisms such as pinocytosis, endocytosis, and phagocytosis.
<xref rid="b75-ijn-10-031" ref-type="bibr">75</xref>
Once the NPs enter the cells, they interact with the cellular materials and cause DNA damage and cell death.</p>
<p>The GSNPs at 85 μg/mL concentration showed 95.23% inhibition of HT29 cell growth. The concentration of the NPs was chosen based on the TC ID
<sub>50</sub>
value (results not shown). Another promising result was that
<italic>G. sylvestre</italic>
plant extracts alone at 85 μg/mL concentration showed 30.77% inhibition of HT29 cell lines growth. From our results, it can be concluded that the GSNPs could have induced intracellular reactive oxygen species generation, which can be evaluated using intracellular peroxide-dependent oxidation, and caused cell death. The control cells were clustered, healthy, and viable cells (
<xref ref-type="fig" rid="f8-ijn-10-031">Figure 8A</xref>
), whereas the HT29 cells’ proliferation was significantly inhibited by GS (
<xref ref-type="fig" rid="f8-ijn-10-031">Figure 8B</xref>
). The SNP-treated cells showed increased apoptotic morphological changes (
<xref ref-type="fig" rid="f8-ijn-10-031">Figure 8C</xref>
), also the clearly visible cell debris in
<xref ref-type="fig" rid="f8-ijn-10-031">Figure 8D</xref>
is due to cell death by 85 μg/mL SNP treatment.</p>
<p>These results indicate that the sensitivity of HT29 human colon cancer cell line for cytotoxic drugs is higher than that of the Vero cell line for the same cytotoxic agents. Sahu et al
<xref rid="b76-ijn-10-031" ref-type="bibr">76</xref>
have reported the presence of four new tritepenoid saponins, namely gymnemasins A, B, C, and D, from the leaves of
<italic>G. sylvestre</italic>
, while Chan has identified the presence of acylation with diangeloyl groups at the C21–22 positions in triterpenoid saponins, which is essential for cytotoxcity toward tumor cells.
<xref rid="b77-ijn-10-031" ref-type="bibr">77</xref>
Tang et al
<xref rid="b78-ijn-10-031" ref-type="bibr">78</xref>
have reported that saponin could induce apoptosis of U251 cells, and both BAD-mediated intrinsic apoptotic signaling pathway and caspase-8-mediated extrinsic apoptotic signaling pathway were involved in the apoptosis.</p>
<p>The promising saponins were further studied as potential anticancer agents by many researchers. Ai et al
<xref rid="b79-ijn-10-031" ref-type="bibr">79</xref>
proposed a qualitative method that can be used to recognize the presence or absence of cancer cells with gold NPs for targeted cancer cell imaging and efficient photodynamic therapy. As reported by Raghavendra et al
<xref rid="b80-ijn-10-031" ref-type="bibr">80</xref>
the size effects and multifunctionality are the main characteristics of NPs, so our method of one-step synthesis of SNPs using the aqueous extract of
<italic>G. sylvestre</italic>
may serve as a potential anticancer drug for cancer therapy. Further studies have to be carried out to understand the nature of cytotoxicity and the death or proliferation of cells caused by GSNPs from
<italic>G. sylvestre</italic>
leaf extract.</p>

<title>Conclusion</title>
<p>The green synthesis of biofunctionalized SNPs from the leaves of
<italic>G. sylvestre</italic>
was economical, nontoxic, and environmentally benign. Due to the reducing and capping nature of the bioactive phytocompounds present in the aqueous extract of
<italic>G. sylvestre</italic>
, a cap was formed around the silver ions of the biofunctionalized SNPs which were stable. The presence of the functional group of the bioactive compounds was confirmed by FTIR spectra. The particle size and the spherical shape of the SNPs were determined by XRD and SEM analyses. Since the plant extract and the biofunctionalized SNPs showed anticancer activity against cancer cells,
<italic>G. sylvestre</italic>
may serve as a source for potential anticancer drugs. The present study showed the anticancer activities of both the bioactive compounds of the leaf extract and the biofunctionalized SNPs synthesized against HT29 human adenocarcinoma cells in vitro. Our studies provide an important basis for the application of NPs for in vitro anticancer activity against human colon adenocarcinoma cells. Our earlier reports have also shown the potential antiulcer properties of
<italic>G. sylvestre</italic>
in mice.
<xref rid="b13-ijn-10-031" ref-type="bibr">13</xref>
So GSS is a good plant candidate for further studies in alternative medicine due its multifunctional medical properties</p>
