Two new alkaloids from Miliusa cuneata.
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.
