Cyperenoic acid and (-)-Hardwlckiic acid from the chloroform extract of the roots of Croton aromaticus : isolation and insecticidal properties

Abstract

Cyperenoic acid and (-)-hardwickiic acid have been bolrted from the chloroform extract of the roots of Croton aromaticus L. Both compounds displayed moderate insecticidal activity against the groundnut aphi4Apbis cmcciboro. Comparison of antifungal and insecticidal properties exhibited by the extracts of C. ammati-cus L. and C. laccifems L. corroborates previous conclusions of chemouxonomic studies that the two taxa be maintained as two d i i c t Species.
