Abstract

A new capsaicin derivative, 6' ',7' '-dihydro-5',5' "-dicapsaicin (1), and a known capsaicin metabolite, omega-hydroxycapsaicin (2),(1) were isolated from the fruit of Capsicum annuum. Their structures were established on the basis of spectroscopic evidence. Compound 1 showed almost the same antioxidant activity as capsaicin, but did not have a pungent taste.

摘要

从辣椒果实中分离出一种新的辣椒素衍生物6''，7''-二氢-5'，5''-二辣椒素（1）和一种已知的辣椒素代谢产物ω-羟基辣椒素（2）。它们的结构是根据光谱证据确定的。化合物1显示出与辣椒素几乎相同的抗氧化活性，但没有辛辣味。
