13-差向异构体-高壳聚糖-5 β-醇，一种新的具有7，6，5-稠合碳骨架的二萜醇，与先前已知的13-epi-neoverrucosan-5 β-醇和倍半萜烯烃，gymnomitrene（= β- barbatene）。通过13-表-新overrucosan-5 β-的核磁共振光谱和化学转化阐明了新二萜类化合物的立体结构用稀酸溶解。
13-epi-Homoverrucosan-5.beta.-ol, a novel diterpene alcohol with a 7,6,5-fused carbon skeleton, was isolated from the New Zealand liverwort, Schistochila nobilis, together with the previously known 13-epi-neoverrucosan-5.beta.-ol and the sesquiterpene hydrocarbon, gymnomitrene (= .beta.-barbatene). The stereostructure of the new diterpenoid was elucidated by NMR spectra and chemical transformation of 13-epi-neoverrucosan-5.beta.-ol by dilute acid.
