从苔类植物黑褐容草（Jungennannia atrobrunnea）中分离得到3个新重排的对映贝壳杉烷型二萜化合物（1-3）和7个新重排的对映贝壳杉烷型二萜化合物（4-10）。通过广泛的光谱技术和X射线晶体学分析确定了它们的结构。这些化合物的绝对构型通过CD光谱研究得到了澄清。化合物1是具有过氧化物桥的重排的对映贝壳杉烷二萜类化合物的第一个实例。
Three new rearranged ent-kaurane-type diterpenoids (1-3) and seven new ent-kaurane-type diterpenoids (4-10) have been isolated from the liverwort Jungennannia atrobrunnea. Their structures were determined by extensive spectroscopic techniques and X-ray crystallographic analysis. The absolute configurations of these compounds were clarified by CD spectroscopic studies. Compound 1 is the first example of a rearranged ent-kaurane diterpenoid possessing a peroxide bridge.
