Resumo: Chemical studies of the leaves of L. divaricata afforded 3beta-p-hydroxybenzoyl-tormentic acid, a triterpene with an ursene-type skeleton, a mixture whose main compound was an oleanene derivative, the maslinic acid, a C-glycoside flavone, vitexin and glucopyranosylsitosterol. A flavonoid, characterized as (-)-epicatechin, which belongs to the flavan-3-ol class, was isolated from the stem's bark. The structures of the compounds were elucidated by spectroscopic analysis. The antibacterial, antifungal and antiproliferative activities of the crude methanolic extracts of leaves and bark were evaluated and the antibacterial properties of the fractions of the barks were also investigated.
