Three triterpenoids were isolated from the stem bark of Pyrus communis Linn. and identified as lup-20(29)-ene-3alpha, 27-diol (1), lup-20(29)-ene-3alpha-ol (2) and lup-20(29)-ene-3alpha, 28-diol (3) on the basis of spectral and chemical analysis. The Compound (1) is a novel triterpene, being reported first time by us.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
