摘要：

A series of scarce triterpenoid alcohols and ketones of the 14 alpha-methyl-9,19-cyclocholestane type has been isolated from roots and aerial parts of Costus tonkinensis. 24-Methylpollinastanone identified by GC-mass spectrometry including deuterium labelling experiments was found as a natural product for the first time. In addition, alpha-amyrin, beta-amyrin, several common phytosterols and some 7-oxosterols were identified. (C) 1997 Elsevier Science Ltd. All rights reserved.
