RESUMO
The control of agriculture plague is relevant to Brazil that has large crop area. The control, by natural product, generally low toxic to humans and to animals and specific to target plague, is recommended. This work presents the phytochemical and insecticide assays carried out with organic extracts of leaves and stems of Rauia sp. Among the tested extracts, the stem extracts were more active on leaf cutter ants (Atta sexdens rubropilosa) and the extracts of leaves were more active against fall armyworm (Spodopera frugiperda). The study of dichloromethane extracts of the stem led to the identification of active substances: sitosterol, stigmasterol, campesterol, clovane-2β,9α-diol, apigenin 6-C-neohesperidosyl-8-Cglucopyranoside, apigenin 6-C-glucopyranosyl-8-C-neohesperidoside, 2-Orhamnosyl- vitexin, 2-O-rhamnosyl-isovitexin, vitexin, isovitexin, apigenin 6-C-β- D-glucopyranosyl-8-C-(2-O-α-L-arabinopyranosyl-β-D-glucopyranoside), apigenin 6-C-(2-O-α-L-arabinopyranosyl-glucopyranosyl)-8-C-β-Dglucopyranoside, vicenin-2, schaftoside, neoschaftoside, isoschaftoside e neoisoschaftoside. The sesquiterpene clovane-2β,9α-diol and glycosides flavonoids were been reported for the first time in the genus Rauia.
