摘要：

A new sesquiterpene and 13 known compounds were isolated from the ether extract of Dumortiera hirsuta. Their structures were established by spectral and chemical evidence and/or X-ray crystallographic analysis. The structure of the new compound was shown to be (4S, 6R)-2,7,10-bisbolatrien-4-ol. The absolute configuration of (4S, 7R)-germacra-1(10)E, SE-dien-11-ol was established by chemical degradation, although it has been reported previously on the basis of the comparison of the magnitude of optical rotation with that of a related known compound. The tentative structure of isomarchantin C has been reported previously, but it has now been established by X-ray crystallographic analysis. Copyright (C) 1996 Elsevier Science Ltd
