Abstract

Cyperenoic acid and (-)-hardwickiic acid have been isolated from the chloroform extract of the roots of Croton aromatieus L. Both compounds displayed moderate insecticidal activity against the groundnut aphid Apbis cnuclvora. Comparison of antifungal and insecticidal properties exhibited by me extracts of C. aromaticus L. and C. lacciferus L. corroborates previous conclusions of chemotaxonomic studies that the two taxa be maintained as two distinct species.
