摘要
A new triterpenoid saponin, vaccariside A 1 was isolated from the seeds of l'accaria segetalis using various chromatographic methods. The structure of compound 1 was elucidated by comprehensive spectroscopic analysis as 3-O-beta-D-galactopyranosyl-(1-2)-[beta-D-quinovpyranosyl-(1-4)-beta-D-xylopyranosyl-(1-3)]-beta-D-glucuronopyranosyl quillaic acid 28-O-beta-D-glucopyranosyl-(1-3)-[beta-D-xylopyranosyl-(1-4)]-alpha-L-rhamnopyranosyl-(1-2)-3-O-acetyl-beta-D-fucopyranoside.
