Identification and quantification of polyphenols in hull, bran and endosperm of common buckwheat (Fagopyrum esculentum) seeds
The distribution of polyphenol profiles in different fractions of buckwheat seeds is less understood. In this study, polyphenols in the hull, bran and endosperm of eight common buckwheat cultivars were studied. The results showed that the hull had highest total phenolic content, followed by bran.

The distribution of polyphenol profiles in different fractions of buckwheat seeds is less understood. In this study, polyphenols in the hull, bran and endosperm of eight common buckwheat cultivars were studied. The results showed that the hull had highest total phenolic content, followed by bran. Total proanthocyanidin contents in the hull were similar to those in the bran. Over 40 phenolics were identified by HPLC/MS. Prominent phenolics such as 1-O-Caffeoyl-6-O-rhamnopyranosyl-glycopyranoside, epicatechin-gallate, orientin/isorientin, vitexin/isovitexin, hyperin and rutin in different seed fractions were identified and quantified.
