摘要Two new triterpenoid saponins, gledistside A (1) and gledistside B (2), isolated from the fruits of Gledistsia dolavayi Franch., were characterized as the 3,28-O-bisdesmoside of echinocystic acid acylated with monoterpene carboxylic acids. On the basis of spectroscopic and chemical evidence, their structures were elucidated as 3-O-beta-D-xylopyranosyl-(1 --> 2)-alpha-L-arabinopyranosyl-(1 --> 6)-beta-D-glucopyranosyl-28-O-beta-D-xylopyranosyl-(1 --> 3)-beta-D-xylopyranosyl-(1 --> 4)-[beta-D-galactopyranosyl-(1 --> 2)-alpha-L-rhamnopyranosyl-(1 --> 2)- -(6-O-[2,6-dimethyl-6(S)-hydroxy-2-trans-2,7-octadienoyl])-beta-D-glucopyranosylechinocystic acid (1) and 3-O-beta-D-xylopyranosyl-(1 --> 2)-alpha-L-arabinopyranosyl-(1 --> 6)-beta-D-glucopyranosyl-28-O-beta-D-xylopyranosyl-(1 --> 3)-beta-D-xylopyranosyl-(1 --> 4)-beta-D-galactopyranosyl-(1 --> 2)]-alpha-L-rhamnopyranosyl-(1 --> 2)-6-O-[2-hydroxymethyl-6-methyl-6(S)-hydroxy-2-trans-2,7-octadienoyl])-beta-D-glucopyranosylechinocystic acid (2). The complete H-1 and C-13 assignments of saponins 1 and 2 were achieved on the basis of 2D NMR spectra including HMQC-TOCSY, TOCSY, H-1-H-1 COSY, HMBC, ROESY and HMQC spectra.
