Abstract
Bowdichia virgilioides, es una planta medicinal utilizada por la etnia Tacana, las hojas de este árbol fueron colectadas, en época seca, en la Prov. Abel Iturralde, Bolivia. Las hojas secas y pulverizadas fueron sometidas a maceración con diclorometano y el extracto crudo no presento actividad antipalúdica a dosis de 10μg/mL, frente a Plasmodium falciparum (cepa F32, sensible a la cloroquina). Estudios cromatográficos del extracto crudo y análisis espectroscópicos de las sustancias aisladas nos han permitido identificar: Lupeol (1), Lupenona (2), β-sitosterol (3), estigmasterol (4) y β-amirina (5), como los principales componentes triterpénicos acompañados de ácidos grasos no identificados.
Bowdichia virgilioides, is a medicinal plant used by the Tacana ethnic group. The leaves of this tree were collected, during the dry season, in the Abel Iturralde province, Bolivia. The dry and pulverized leaves were macerated with methilenechloride, and the raw extract did not show activity at 10μg/mL, against Plasmodium falciparum (strand F32, sensible to chloroquine). Chromatographic studies of the crude extract and spectroscopical analysis of the isolated substances allowed us to identify: Lupeol (1), Lupenone (2), β-sitosterol (3), stigmasterol (4) and β-amyrine (5), as the main triterpenes components along with non identified fatty acids.
