Abstract
A new triterpene, A(1)-1-benzoate-19α-hydroxy-urs-2(3),12(13)-dien-28-oic acid (1), was isolated from Hyptis verticillata, in addition to the known triterpenes tormentic acid, isolated as the diacetate (2), betulinic acid (3), α- and β-amyrin, oleanolic acid and ursolic acid. The structure of 1 was elucidated by spectroscopic analysis. Compounds 1–3 exhibited insecticidal activity against the sweet potato weevil Cylas formicarius elegantulus (Summers).
