ANTIOXIDATIVE FLAVONOID GLYCOSIDES FROM QUINOA SEEDS (CHENOPODIUM QUINOA WILLD)
Abstract
Six flavonol glycosides have been isolated from quinoa seeds (Chenopodium quinoa Willd) via normal phase and reverse phase column chromatography. On the basis of spectral data, their structures were established as kaempferol 3‐O‐[β‐D‐apiofuranosyl(1′–2″)]‐β‐D‐galactopyranoside (1), kaempferol 3‐O‐[α‐L‐rhamnopyranosyl(1″–2″)]‐β‐D‐galactopyranoside (2), kaempferol 3‐O‐[β‐D‐apiofuranosyl(1′–2″)‐α‐L‐rhamnopyranosyl(1″–6″)]‐β‐D‐galactopyranoside (3), kaempferol 3‐O‐(2,6‐di‐α‐L‐rhamnopyranosyl)‐β‐D‐galactopyranoside (4), quercetin 3‐O‐[β‐D‐apiofuranosyl (1′–2″)‐α‐L‐rhamnopyranosyl(1″–6″)]‐β‐D‐galactopyranoside (5) and quercetin 3‐O‐(2,6‐di‐α‐L‐rhamnopyranosyl)‐β‐D‐galactopyranoside (6). Among them, compounds 1, 4 and 6 were the main flavonoid glycosides found in quinoa seeds and compounds 2, 5, and 6 were isolated from this plant for the first time. All six compounds exhibited antioxidant

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
