Pentacyclic triterpenoids fromMallotus apelta

Abstract
A new triterpene (1) and six known pentacyclic terpenoids (2-7) were isolated from the methanol extract of the dried leaves fromMallotus apelta. Based on the spectral and chemical evidence, their structures were determined to be 3α-hydroxyhop-22(29)-ene (1), hennadiol (2), friedelin (3), friedelanol (4), epifriedelanol (5), taraxerone (6), and epitaraxerol (7).
