Abstract:
From the isopropyl acetate fraction obtained by partition of the leaves ethanolic extract of Alchornea glandulosa, six phenolic compounds were isolated and identified. General lethality of the extract, fractions and compounds were assayed with Brine Shrimp Test (BST) and with Antifeedant Activity Bioassay (AAB) against neonate larvae of Spodoptera frugiperda. Aqueous fraction and ethyl gallate, one of the major constituents of the polar fraction, have shown the highest toxicity in BST. Ethanolic extract, isopropyl acetate fraction and gallic acid reduced significantly larval growth of S. frugiperda neonates.
