摘要	Two new 24-methylene tetracyclic triterpenes that possess the lanostane skeleton have been isolated from the stem barks of Polyalthia lamcilimba. Their structures were determined by spectral analysis and comparisons with other lanostane type triterpenes described in the literature. The two new components (1 and 3) were elucidated as 24-methylenelanosta-7,9( Il)-dien-3 beta,15 alpha-diol and 24-methylenelanosta-8-en-2 beta,3 beta,21-triol.
