From the roots of this plant, three triterpenoids were isolated and the structures were es-tablished on the basis of spectral and chemical evidence. So, these compounds are 3β-hydroxylup-30-ene-28-oic acid(betulinic acid), 2α, 3α, 19α-trihydroxyurs-12-ene-28-oic acid(euscaphic acid) and 2α, 3β, 19α-trihydroxyurs-12-ene-28-oic acid(tormentic acid), respectively.
