Abstract
Five new podocarpane-type trinorditerpenes were isolated from the bark of T aiwania cryptomerioides. Structures of 1 beta, 14-dihydroxy-13-methoxy-6,8, 11,13-podocarpatetraene (1), 1 beta,14-dihydroxy-13-methoxy-8,11,13-podocar patriene (2), 13-hydroxy-12-methoxy-8,11,13-podocarpatrien-3-one (3), 14-hy droxy-13-methoxy-1,8,11,13-podocarpatetraen-3-one (4), and 13-methoxy-8,12- podocarpatriene-11,14-dione (5) were determined by NMR, MS, and other spect ral and chemical evidence.
