Aislamiento, caracterización e identificación y evaluación de la actividad biológica de metabolitos secundarios de la especie Heliocarpus americanus.

Abstract

Abstract In the present phytochemical study of the species Heliocarpus americanus L. collected in the Quilanga canton of the province of Loja, three extracts were obtained: hexane, acetate and methanol. Of which 6 compounds of the acetate extract known as squalene, stigmasterol,-sitosterol, palmitic acid, ethyl stearate and Oleanolic acid were identified, and methanolic extract identified 3 compounds known as sucrose, Ziyu glycoside I and rosmarinic acid the same which were identified by means of NMR, FT-IR. The antimicrobial activity was evaluated by means of the broth microdilution test in which the methanol extract showed moderate activity and the antioxidant activity by means of the DPPH, of the total extracts, of which all showed very strong antioxidant activity.
