Abstract
Two new isoquinoline alkaloids, 2,10-dimethoxy-3,11-dihydroxy-5,6-dihydroprotoberberine (1) and 1,9-dihydroxy-2,11 -dimethoxy-4,5-dihydro-7-oxoaporphine (2), together with thirteen known alkaloids, were isolated from the ethanolic extracts of the stem and leaves of Miliusa cuneata (Graib). Their structures were elucidated predominantly by spectral evidence.
摘要
从楔叶野独活（Miliusa cuneata (Graib)）的茎和叶的乙醇提取物中分离出两种新的异喹啉生物碱，2,10-二甲氧基-3,11-二羟基-5,6-二氢原小檗碱（1）和1,9-二羟基-2,11-二甲氧基-4,5-二氢-7-氧代阿朴啡（2），以及十三种已知生物碱。它们的结构主要通过光谱证据得以阐明。
