Obtención de extractos, aislamiento y caracterización de metabolitos secundarios de Erythrina edulis

Abstract

Were obtained extracts of Erythrina edulis specie (in hexane, ethyl acetate, and methanol) were collected in the district of Argelia, Loja province, for phytochemical study. The ethyl acetate extract (from the leaves) had better performance (2.63%) than the other extracts and contained a whitish solid identified as tridecyl-ferulate (1), which had a retention time of 25.93 minutes and a melting point of 55 - 58° C; compound identification was performed via GC/MS and 1H/13C NMR. The methanol extract (from the stems) contained a white solid that had a retention time of 28.38 minutes and a melting point 65 - 68° C; compound identification via GC/MS suggests that the compound was ethyl ciclocosane (2). The methanol extract also contained another whitish solid with a melting point of 75 - 79° C and four different retention times in GC/MS. According to the Wiley database 7n.l, these compounds might be: 2-acetyl-6-methoxynaphthalene (3), 13-tertadecen-1-ol acetate (4), ciclotetracosane (5), and 1-docosene (6).
