Abstract:
A new aporphine alkaloid (1), together with five known analogues (2-6), has been isolated from the branch of Litsea greenmaniana by using various chromatographic techniques. Their structures were identified by spectroscopic data analysis ( MS, IR, 1D and 2D NMR) as 2,9-dihydroxy-1,10-dimethoxy-4,5-dihydro-7-oxoaporphine (1), laurotetanine (2), N-methyllaurotetanine (3), isodomesticine (4), isocorydine (5), and norisocorydine (6). Compound 1 was a new compound, and compounds 2-6 were obtained from this plant for the first time.
