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.
从 Carapa guianensis 的种仁和 Cabralea canjerana（楝科）的果实和种子中分离得到的两种三萜烯，ocotillone 和 cabraleadiol，以及四种 limonoids，methyl angolensate、3-β-去乙酰基 fissionolide、7-去乙酰氧基-7-氧代 gedunin 和 β-光 gedunin，其活性被评估针对秋粘虫 Spodoptera frugiperda。gedunin 被用作阳性对照。7-去乙酰氧基-7-氧代 gedunin 和 β-光 gedunin 降低了蛹重，就像 gedunin 一样。Cabraleadiol、3-β-去乙酰基 fissionolide 和 7-去乙酰氧基-7-氧代 gedunin 使幼虫期延长，类似于 50.0mgkg(-1) 时约 1.2 天的对照（gedunin）。β-光 gedunin 的杀虫活性最高。
