Abstract
This study was designed to determine the proximate composition and mineral content of
The proximate composition and mineral analysis of
Proximate analysis revealed that the carbohydrate content was highest in the leaf (55.83 ± 3.71%) and stem (50.38 ± 1.27%) while crude fat content was lowest in the leaf (1.83 ± 0.43%) and stem (1.75 ± 0.48%). The minerals detected in appreciable quantity in both the leaf and stem samples were calcium, magnesium, potassium, sodium, chromium, lead, manganese, nickel, and copper. Further study showed that the aqueous leaf fraction exhibited a significantly (
The findings from this study indicate that

In addition, this study may also explain the folkloric use of crude <italic>C. afer</italic> leaf or stem extracts in the treatment of oxidative stress associated diseases, including rheumatoid arthritis and hepatic disorder.</p></sec></abstract><kwd-group><title>KEY WORDS:</title><kwd>Antioxidant</kwd><kwd><italic>Costus afer</italic></kwd><kwd>mineral</kwd><kwd>plant</kwd><kwd>proximate</kwd></kwd-group></article-meta></front></pmc><affiliations><list><country><li>Nigeria</li></country></list><tree><country name="Nigeria"><noRegion><name sortKey="Anyasor, G N" sort="Anyasor, G N" uniqKey="Anyasor G" first="G.
