Effect of Triterpenoids and Limonoids Isolated from Cabralea canjerana and Carapa guianensis (Meliaceae) against Spodoptera frugiperda (J. E. Smith)

Year: 2011

Type: article

Abstract: The activities of two triterpenoids, ocotillone and cabraleadiol, and four limonoids, methyl angolensate, 3-beta-deacetylfissinolide, 7-deacetoxy-7-oxogedunin, and beta-photogedunin, isolated from arillus of Carapa guianensis and fruits and seeds of Cabralea canjerana (Meliaceae), were evaluated against the fall armyworm Spodoptera frugiperda. Gedunin was used as a positive control. 7-Deacetoxy-7-oxogedunin and beta-photogedunin reduced the pupal weight as occurred with gedunin. Cabraleadiol, 3-beta-deacetylfissinolide, and 7-deacetoxy-7-oxogedunin prolonged the larval phase similar to the control (gedunin) of approximately 1.2 days at 50.0 mg kg(-1). The highest insecticidal activity was obtained for beta-photogedunin.
