VALENCIA, Zanhy et al. Bioactive compounds and antioxidant activity from Peruvian quinoa seeds (Chenopodium quinoa W.). Rev. Soc. Quím. Perú [online]. 2017, vol.83, n.1, pp.16-29. ISSN 1810-634X.

We investigated reducing sugars, bioactive compounds and antioxidant activity of 24 accessions of quinoa of the national collection of INIA Peru. The seeds showed total phenolic between 0,783 to 3,437 mg GAE/g, total flavonoids between 0,199 and 1,029 mg CE/g sample, betacyanins and betaxanthins in amounts not significant and reducing sugars between 30,973 and 88,278 mg of glucose equivalent/g sample. The antioxidant activity by DPPH and ABTS showed significant differences between different quinoa seeds studied
