Preliminary Phytochemical Screening, Quantification of phenolic compounds, of Plant Extract from Chenopodium quinoa

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 comarin 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
