Extracción, aislamiento e identificación de metabolitos secundarios del extracto metanólico de la especie Ageratina dendroides (Spreng.) R.M. & H. Rob. (Asteraceae)

Abstract

Abstract: The present phytochemical study of the leaves of Ageratina dendroides belonging to the Asteraceae family, native to the tropical humid montane forests of Ecuador, was carried out using the methanolic extract. The compounds were obtained by column chromatography and the identification of the compounds wasthrough spectroscopic techniques such as NMR with a frequency of 500 MHz for 1H-NMR and 125 MHz for 13C-NMR, and by comparison of literature reports. Two compounds of the flavonoid group known as: 5-hydroxy-3,7,4-trimethoxyflavone and 5-hydroxy-,7,4-dimethoxyflavone were isolated and characterized.
