Preliminary Phytochemical Screening, Quantification of phenolic compounds, of Plant Extract from <i>Chenopodium quinoa</i>

Abstract

The aim of this study was to screening the phytogenic chemical compounds of the seeds of Chenopodium quinoa, obtained from Wilaya of El-Oued.  The chemical study showed that the plant contained a number of secondary metabolites, flavonoids, tannins, saponins, steroids and triterpenes,  glycosids while the absence of alkaloids and coumarin in Chenopodium quinoa. Folin-Ciocalteau colorimetric were used to determine the total  phenolic con-tent (TPC), in the hydroalcoholic seeds extracts. The yield of the methanolic extract was estimated at 36.66%. As for the quantitative  content of polyphenols, it is 11.647 ± 1.91μg AGE / mg extrait From this, Chenopodium quinoa is considered a nutritional and therapeutic value  because it contains secondary metabolites
