摘要：

Three new cycloartane glycosides, named cyclotricuspidosides A, B and C, were isolated from the leaf and stem pacts of Trickosanthes tricuspidata. The structure of the compounds have been determined as 28,31-di-O-beta-D-glucopyranosides of 1 alpha,3 beta-24 xi,31-tetrahydroxy-24 xi,-methyl-cycloartan-28-oic acid, 1 alpha,3 beta,16 beta,24 xi,31-pentahydroxy-24 xi,-methylcycloartan-28-oic acid and 1 alpha,3 beta,16 alpha,24 xi,31-pentahydroxy-24 xi,-methylcycloartan-28-oic. These structural elucidations were based on analyses of chemical and spectroscopic data. (C) 1999 Elsevier Science Ltd. All rights reserved.
