Two new 8-oxotetrahydroprotoberberine alkaloids, gusanlung A and B, from Acangelisia gusanlung.
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.
