Abstract
Three novel polyhydroxylated triterpenes have been isolated from Uncaria tomentosa. Their structures were established as 1, 2, and 3 by detailed spectral studies including 1H-13C correlations via long range couplings using the INAPT pulse sequence, nOeds, and 2D 1H-13C direct chemical shift correlation (HETCOR) nmr techniques.
摘要
从毛钩藤中分离出了三种新型多羟基三萜。通过详细的光谱研究，包括使用INAPT脉冲序列通过远程耦合进行的¹H-¹³C相关、核Overhauser效应（nOeds）以及二维¹H-¹³C直接化学位移相关（HETCOR）核磁共振技术，确定了它们的结构分别为1、2和3。
