摘要：

A new myltaylane-type sesquiterpene alcohol and nine known sesquiterpenoids were isolated from Bazzania trilobata. The absolute stereostructure of (1S,4S)-cis-5-hydroxycalamenene was revised to be (1R,4R)-cis-5-hydroxycalamenene by the X-ray crystallographic analysis of its p-bromobenzoate derivative. Four previously known sesquiterpenoids were isolated from Porella canariensis, together with an artefact of a pinguisane-type sesquiterpene lactone. Their structures were determined by the use of extensive NMR techniques.
