and B-4, and the prodelphinidins gallocatechin-(4α,8)-catechin, gallocatechin-(4α,8)-epicatechin and gallocatechin-(4α,8)-epigallocatechin have been isolated from the testa of faba beans and characterized by means of spectroscopic methods. Proanthocyanidin samples were compared for their trypsin inhibitory activity. The results suggest that the degree of polymerization, the number of phenolic hydroxyl
摘要 在一项化学研究中,表儿茶素、表没食子儿茶素、原花青素 B-1、B-3 和 B-4,以及原飞燕草素没食子儿茶素-(4α,8)-儿茶素、没食子儿茶素-(4α,8)-表儿茶素和没食子儿茶素-(4α ,8)-表没食子儿茶素已从蚕豆的种皮中分离出来,并通过光谱方法进行了表征。比较原花青素样品的胰蛋白酶抑制活性。结果表明聚合度、酚羟基数量和组成单元的2,3-立体化学显着影响抑制强度。
