Five new diterpenes, 3beta-acetoxyabieta-8,11,13-trien-12-ol (1), 8alpha-hydroxy-13(16),14-labdadien-19-al (2), 16-hydroxy-19-oxomanoyl oxide (3), 15-nor-14-oxo-8(17), 12-labdadiene-18-ol (4), and 15,16-bisnor-13-oxo-8(17), 11-labdadien-18-ol (5), were isolated from the wood of Cunninghamia konishii. Their structures were elucidated by 2D NMR spectroscopy and by chemical methods.
从台湾杉木木材中分离得到了5个新的二萜类化合物，分别为3β-乙酰氧基枞-8,11,13-三烯-12-醇（1）、8α-羟基-13(16),14-赖百当二烯-19-醛（2）、16-羟基-19-氧代马尼醇氧化物（3）、15-降-14-氧代-8(17),12-赖百当二烯-18-醇（4）和15,16-双降-13-氧代-8(17),11-赖百当二烯-18-醇（5）。通过二维核磁共振波谱法和化学方法对其结构进行了鉴定。
