Abstract

A new triterpene compound (1), along with arjunolic acid, was isolated from an ethanol extract of the whole plant of Leandra chaetodon. Based on spectroscopic analysis, the structure of 1 was determined as 2α,6α- dihydroxybetulinic acid. Arjunolic acid showed inhibitory activity against Cryptococcus neoformans. (IC50 = 20 μg/mL).
