Abstract
Two new 8-oxotetrahydroprotoberberine alkaloids, gusanlung A (1) and B (2), together with known isoquinoline alkaloids, berberine and jatrorrhizine, were isolated from the Chinese medicinal plant Acangelisia gusanlung H. S. Lo (Menispermaceae). Their structures were elucidated mainly by spectroscopic analysis.Keywords
