Isolamento, determinação estrutural e atividades antitumoral e anti-inflamatória de triterpenos isolados de Vochysia cinnamomea (Vochysiaceae)

Abstract

This work describes the study of plant extracts Vochysia cinnamomea Vochysiaceae, aiming to isolate and identify promising substances which has antitumor activities and anti-inflammatory properties. Extract of stem bark were isolated two triterpenes: lupeol and betulinic acid and a steroid: β-sitosterol. Extracts of the leaves were isolated three triterpenes: α-amyrin, β-amyrin and ursolic acid. The tests were carried forward to the antitumor cell lines MDA-MB-435 (melanoma), HCT-8 (human-colon) and SF-295 (central nervous system) with substances: Lupeol, betulinic acid, ursolic acid and mixing α and β amyrin showing no relevant activity. Triterpenes: lupeol and betulinic acid were tested for anti-inflammatory activity by the acetic acidinduced abdominal writhing method, but only the betulinic acid activity was satisfactory at a concentration of 30 mg / kg and Lupeol the concentration of 10mg/kg was inactive.
