摘要：

From the ether extract of the liverwort Odontoschisma denudatum, three novel ent-bibsane- and a novel dolabellane-type diterpenoids have been isolated. Their absolute structures were determined by a combination of PD-NMR X-ray crystallographic analysis, modified Mosher method and chemical degradation. (C) 1998 Elsevier Science Ltd.
