Catechins as Antioxidants from Buckwheat (Fagopyrum esculentum Moench) Groats
Abstract
Four catechins and rutin were isolated from ethanol extracts of buckwheat ( Fagopyrum esculentum Moench) groats by Sephadex LH-20 column chromatography and preparative HPLC with monitoring of the peroxyl radical scavenging activity. The antioxidant activity of these catechins was higher than that of rutin. The structures of these catechins were established as (−)-epicatechin, (+)-catechin 7- O -β- d -glucopyranoside, (−)-epicatechin 3- O - p -hydroxybenzoate, and (−)-epicatechin 3- O -(3,4-di- O -methyl)gallate on the basis of 1 H, 13 C, and two-dimensional nuclear magnetic resonance techniques and fast atom bombardment mass spectrometry. The yields of these antioxidant compounds suggest that they are abundant, as is rutin, which is known as a biological phytochemical in buckwheat groats. Keywords: Fagopyrum esculentum; antioxidant activity; flavonoids; (−)-epicatechin; (+)-catechin 7- O -β- d -glucopyranoside; (−)-epicatechin 3- O - p -hydroxybenzoate; (−)-epicatechin 3- O -(3,4-di- O -methyl)gallate

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.
