PRELIMINARY QUALITATIVE FITOCHEMICAL STUDY AND QUANTIFICATION OF FLAVONOIDS AND TANNINS OF ETHANOLIC EXTRACT OF LEAVES OF Desmodium vargasianum Schubert

Descripción del Articulo

In this work the secondary metabolites of Desmodium. vargasianum Schubert “pie de perro” leaves ethanolic extract was investigated. The phytochemical screening realized on the ethanolic extract suggests the presence of phenolic compounds (flavonoids, tannins) and alkaloids. The thin layer chromatogr...

The thin layer chromatography was positive for flavonoids, tannins and alkaloids. Finally, total flavonoids and total tannins were quantified. In the quantification of total flavonoids by UV-VIS spectrophotometry, 202,05 ± 1,10 mg QE/g of ethanolic extract (EE) was obtained.

El tamizaje fitoquímico realizado en el extracto etanólico sugiere la presencia de compuestos fenólicos (flavonoides, taninos) y alcaloides. Se realizó la cromatografía en capa fina, dando positivo flavonoides, taninos y alcaloides. Finalmente se cuantificaron flavonoides totales y taninos totales. En la cuantificación de flavonoides totales por espectrofotometría UV-VIS se obtuvo 202,05 ± 1,10 mg QE/g de extracto etanólico (EE). En cuanto a la cuantificación de taninos totales por espectrofotometría UV-VIS se obtuvo 178,50 ± 0,75 mg ATE/g de EE.Sociedad Química del Perú2018-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontexttextoapplication/pdfhttp://revistas.sqperu.org.pe/index.php/revistasqperu/article/view/13910.37761/rsqp.v84i2.139Revista de la Sociedad Química del Perú; Vol. 84 Núm. 2 (2018): Revista de la Sociedad Química Del Perú; 175 - 182Journal of the Chemical Society of Peru; Vol. 84 No. 2 (2018): Journal of Sociedad Química Del Perú; 175 - 1822309-87401810-634X10.37761/rsqp.v84i2reponame:Revista de la Sociedad Química del Perúinstname:Sociedad Química del Perúinstacron:SQPspahttp://revistas.sqperu.org.pe/index.php/revistasqperu/article/view/139/119Derechos de autor 2018 Sociedad Química del Perúhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccessoai:rsqp.revistas.sqperu.org.pe:article/1392020-03-03T22:08:08Z
