摘要：

Four new saponins, 3-beta-O-[alpha-L-rhamnopyranosyl(1 --> 3)-beta-glucuronopyranosyl]-2 beta,3 beta-dihydroxyolean-12-en-28-oic acid 28-O-[beta-D-glucopyranosyl] ester, 3-beta-O-[alpha-L-rhamnopyranosyl(1 --> 3)-beta-glucuronopyranosyl]-2 beta,3 beta,23-trihydroxyolean-12-en-28-oic acid 28-O-[beta-D-glucopyranosyl] ester, 3-beta-O-[alpha-rhamnopyranosyl(1 --> 3)-beta-glucuronopyranosyl]-2 beta,3 beta-dihydroxy-23-oxoolean-12-en-28-oic acid 28-O-[beta-D-glucopyranosyl] ester, 3-beta-O-[beta-glucuronopyranosyl]-2 beta,3 beta-dihydroxy-30-norolean-12,20(29)-diene-23,28-dioic acid 28-O-[beta-D-glucopyranosyl] ester, together with known chondrillasterol (5 alpha-stigmasta-7,22-dien-3 beta-ol) and its 3-O-glucopyranoside have been isolated from seeds of Amaranthus cruentus. The structures were established by LSI mass spectrometry and NMR spectroscopy. (C) 1998 Elsevier Science Ltd. All rights reserved.
