摘要：

Four novel triterpenoid saponins were isolated from the seeds of Vaccaria segetalis. Their structures were established as vaccaroside A, gypsogenic acid-28-O-beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranosyl-(1 --> 6)-[beta-D-glucopyranosyl-(1 --> 3)]-beta-D-glucopyranoside; vaccaroside B, gypsogenic acid-28-O-beta-D-glucopyranosyl-(1 --> 2)-[3-hydroxyl-3-methylglutaroyl-(1 --> 6)]-beta-D-glucopyranosyl-(1 --> 6)-[beta-D-glucopyranosyl-(1 --> 3)]-beta-D-glucopyranoside; vaccaroside C, 23-O-beta-D-glucopyranosyl-gypsogenic acid-28-O-beta-D-glu copyranosyl-(1 --> 2)-beta-D-glucopyranosyl-(1 --> 6)-[beta-D-glucopyranosyl-(1 --> 3)]-beta-D-glucopyranoside and vaccaroside D, 3,4-secogypsogenic acid-28-O-beta-D-glucopyranosyl-(1 --> 3)-[beta-D-glucopyranosyl-(1 --> 6)]-beta-D-glucopyranoside by a combination of extensive NMR (DEPT, COSY, HOHAHA, HETCOR, HMBC and NOESY) studies and chemical degradation.
