Abstract
Six podocarpane-type trinorditerpenes were isolated from the bark of Taiwania cryptomerioides. Thier structures, 14-hydroxy-13-methoxy-8, 11, 13-podocarpatrien-7-one (1), 13-hydroxy-12-methoxy-8, 11, 13-podocar-patriene (2), 12-hydroxy-13-methoxy-8, 11, 13-podocarpatriene (3), 14-hydroxy-13-methoxy-8, 11, 13-podocarpatriene (4), 13-hydroxy-8, 11, 13-podocarpatriene (5), and 13, 14-dihydroxy-8, 11, 13-podocarpatrien-7-one (6), were determined principally from spectral evidence.
