摘要

Separation of the water-soluble fraction of peanut skins led to the isolation of five proanthocyanidins. Based on the spectroscopic investigation and partial acid catalyzed degradation, their structures were determined to be epicatechin-(2β→ O→ 7, 4β→ 6)- [epicatechin-(4β→ 8)]-catechin (1), epicatechin-(2β→ O→ 7, 4β→ 8) epicatechin-(4β→ 8)- catechin-(4α→ 8)-epicatechin (2), and procyanidins B2 (3), B3 (4) and B4 (5). The ...
