Further studies on the bark of Taiwania cryptomerioides found four new podocarpane derivatives, 1beta,13-dihydroxy-8,11,13-podocarpatriene (1), 14,18-dihydroxy-13-methoxy-8,11,13-podocarpatriene (2), 1beta,14-dihydroxy-13-methoxy-8,11,13-podocarpatriene-2,7-dione (3), and 3beta,14-dihydroxy-13-methoxy-8,11,13-podocarpatrien-7-one (4), together with a known 1beta,13,14-trihydroxy-8,11,13-podocarpatrien-7-one (5). Those structures were elucidated principally from spectral evidence.
对台湾杉树皮的进一步研究发现了四种新的罗汉松烷衍生物,1β,13-二羟基-8,11,13-罗汉松三烯(1)、14,18-二羟基-13-甲氧基-8,11,13-罗汉松三烯(2)、1β,14-二羟基-13-甲氧基-8,11,13-罗汉松三烯-2,7-二酮(3)和3β,14-二羟基-13-甲氧基-8,11,13-罗汉松烯-7-酮(4),以及一种已知的1β,13,14-三羟基-8,11,13-罗汉松烯-7-酮(5)。这些结构主要通过光谱证据得以阐明。
