Aislamiento, caracterización de metabolitos secundarios y evaluación de la actividad biológica de Croton lehmannii Pax

Abstract

Abstract: In the present work of a phytochemical study of the species Croton lehmanniiPax, collected in the Loma la Torre sector, located in the Saraguro canton of the city of Loja.Using chromatographic techniques, the following compounds were identified: the flavonoid tilirosido and the flavonoid rutin. For the identification of thecompounds, CC, TLC, NMR were performed and verified with bibliographic data.In the study of antimicrobialactivity it was obtained as a result that none of the three extracts presented antimicrobial activity, thus concluding that it is inactive for the three different solvents (hexane, ethyl acetate and methanol).Therefore it is recommended to carry out thephytochemical study with diferente solvents and with different parts of the plant matter to obtain interesting results from the chemical point of view.
