Abstract: From the fruits of Gleditsia delauayi Franch.,a new triterpenoid saponin GS_C′was isolated and its structure was determined to be 3-0-β-D-xylopyranosyl(1→2)-a-L-arabinopyranosyl(1→6)-β-D-glucopyranosyl-28-O-β-D-xylopyranosyl(1→3)-β-D-xylopyranosyl(1→4)-a-L-Rhamnopyranopyl (1→2)-[a-L-rhamnopyranodyl(1→6)]-β-D-glucopyranosyl echinocystic acid.Complete assignments of1 H and 13 C spectra of CS-C′were achieved by 2D NMR spectra, such as TOCSY ,1H-1H COSY, HMQC,HMQC-TOCSY,HMBCand ROESY.
