Abstract: Four new triterpene acids,2α,3α, 19α-trihydroxy-11-oxo-urs-12-en-28-oic acid(1) ,2α,3α, 11α, 19α-tetrahydroxy-urs12-en-28-oic acid(2), 2α, 3α-dihydroxy-19-oxo-18, 19-seco-urs-11, 13 ( 18)-dien-28-oic acid(3) and 2α, 3β, 19α-trihydroxyolean-11, 13( 18)-dien-28-olic acid(4)were isolated from the stem of Toddalia asiatica, along with the known compounds euscaphic acid (5), arjunic acid(6), toddaculin, toddalolactone and β-sitosterol. Their structures were elucidated on the basis of spectral evidence.
