Abstract
Two new triterpenoids, olean-18-en-3beta-O-E-coumaroyl ester (1) and olean-18-en-3beta-O-Z-coumaroyl ester (2), were isolated from the stem bark of marine mangrove plant Barringtonia racemosa, along with five known compounds, germanicol, germanicone, betulinic acid, lupeol, and taraxerol. Their structures were determined mainly by spectroscopic methods.
