Abstract
The changes of dynamics of total polyphenolics formation in various anatomical parts (stems, leaves, flowers and seeds) of common buckwheat (Fagopyrum esculentum Moench.) during vegetation period were surveyed. Six cultivars were analysed: Pyra, Spacinska, Emka, Kasho, Jana C1 and Hrusowska. The content of total polyphenolics was evaluated in growth phase I. (formation of buds), in phase II. (at the beginning of flowering), in phase III. (full blossoming) and in phase IV. (full ripeness). The total polyphenolics content was assessed by using Folin-Ciocalteau assay spectrophotometrically on Shimadzu UV-1800. When evaluating all four anatomical parts of common buckwheat we can state that the flowers contained the highest concentration of total polyphenolics where the values were in range from 14.93 to 25.16 mg.g-1. In last phase (IV. phase) where stems, leaves, and seeds were evaluated, buckwheat leaves exerted the highest content of these compounds, and the values were in range from 68.74 to 90.27 mg.g-1. Maximal increase of total phenolics content was manifested in each variety in phase IV., i.e. at the end of the vegetation period. From the standpoint of the content of total polyphenolics in individual anatomical parts the cultivars Pyra, Hrusowska and Emka were the most suitable ones as functional foods.

When evaluating all four anatomical parts of common buckwheat we can state that the flowers contained the highest concentration of total polyphenolics where the values were in range from 14.93 to 25.16 mg.g-1. In last phase (IV. phase) where stems, leaves, and seeds were evaluated, buckwheat leaves exerted the highest content of these compounds, and the values were in range from 68.74 to 90.27 mg.g-1. Maximal increase of total phenolics content was manifested in each variety in phase IV., i.e. at the end of the vegetation period. From the standpoint of the content of total polyphenolics in individual anatomical parts the cultivars Pyra, Hrusowska and Emka were the most suitable ones as functional foods.</abstract><abstract lang="sl">Proučevane so razlike v vsebnosti skupnih polifenolov v delih rastlin (stebla, listi, cvetovi in semena) pri navadni ajdi (Fagopyrum esculentum Moench.) med rastjo. Proučevanih je bilo šest kultivarjev: Pyra, Spacinska, Emka, Kasho, Jana C1 in Hrusowska. Koncentracija skupnih polifenolov je bila raziskana v rastni fazi I. (formiranje socvetij), v fazi II. (začetek cvetenja), v fazi III. (polno cvetenje) in v fazi IV. (polna zrelost). Koncentracija skupnih polifenolov je bila analizirana spektrofotometrično z uporabo reagenta Folin-Ciocalteau na aparaturi Shimadzu UV-1800. Najvišja koncentracija polifenolov je bila v cvetovih (14,93 do 25,16 mg.g-1). V zrelosti (IV. faza) je bilo največ polifenolov v listih (68,74 do 90,27 mg.g-1). Vsebnost polifenolov se je pri vseh kultivarjih povečala v fazi IV., to je na koncu rasti. Glede na vsebnost skupnih polifenolov v posameznih delih rastlin so kultivarji Pyra, Hrusowska in Emka najbolj primerni za uporabi pri pripravi funkcijskih živil.</abstract><subject lang="en"><genre>Keywords</genre><topic>total polyphenolics</topic><topic>buckwheat</topic><topic>anatomic parts</topic></subject><subject lang="sl"><genre>Keywords</genre><topic>skupni polifenoli</topic><topic>ajda</topic><topic>deli rastlin</topic></subject><relatedItem type="host"><titleInfo><title>Acta agriculturae Slovenica</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">1581-9175</identifier><identifier type="eISSN">1854-1941</identifier><identifier type="PublisherID">ACAS</identifier><part><date>2010</date><detail type="volume"><caption>vol.</caption><number>95</number></detail><detail type="issue"><caption>no.</caption><number>3</number></detail><extent unit="pages"><start>225</start><end>229</end></extent></part></relatedItem><identifier type="istex">8C0BFFC0733045D71A94D2667EE174D309E6C8FA</identifier><identifier type="DOI">10.2478/v10014-010-0014-0</identifier><identifier type="ArticleID">v10014-010-0014-0</identifier><identifier type="pdf">v10014-010-0014-0.pdf</identifier><accessCondition type="use and reproduction" contentType="open-access">This content is open access.</accessCondition><recordInfo><recordContentSource>De Gruyter</recordContentSource></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
