title: A novel triterpene from Centella asiatica.
abstract: A novel triterpene, 2alpha,3beta,20,23-tetrahydroxyurs-28-oic acid (1), was isolated from the aerial part of Centella asiatica. Its structure was elucidated by spectroscopic methods, including 2D-NMR spectra. It displayed no activity against Hela and A549 cell lines at concentrations of 10 and 30 microg/mL, respectively.
