• Centella asiatica
• 2 alpha,3 beta,23-trihydroxyurs-20-en-28-oic acid
• 2 alpha,3 beta,23-trihydroxyurs-20-en-28-oic acid O-alpha-L-rhamnopyranosyl-(1 -> 4)-O-beta-D-glucopyranosyl-(1-6)-O-beta-D-glueopyranosyl ester

A new triterpene and a saponin, named 2 alpha,3 beta,23-trihydroxyurs-20-en-28-oic acid (1) and 2 alpha,3 beta,23-trihydroxyurs-20-en-28-oic acid O-alpha-L-rhamnopyranosyl-(1 -> 4)-O-beta-D-glucopyranosyl-(1 -> 6)-O-beta-D-glucopyranosyl ester (2), have been isolated from the aerial part of Centella asiatica. Their structures were elucidated by spectral methods, including 2D-NMR spectra.
