ANÁLISIS BIOQUÍMICO DE DOS FRACCIONES CON ACCIÓN ANTICOAGULANTE DE LAS HOJAS DE Oenothera rosea “CHUPASANGRE”

Abstract: Tradicionalmente las hojas de Oenothera rosea “chupasangre” son usadas para reducir los hematomas, por lo que, esta investigación estuvo dirigida a la evaluación de los componentes capaces de retardar la coagulación sanguínea. Del extracto etanólico de O. rosea se separó por cromatografía de capa fina en celulosa, usando etanol: agua (1:5), dos fracciones F-2 y F-5, que luego fueron preincubadas por 10 minutos con trombina y el veneno de la serpiente Lachesis muta, rico en Enzima Semejante a Trombina (EST) y l… Show more

“…Our results show that the total extract of P. aduncum has a greater capacity than its fractions to inhibit PLA2 of L. muta muta venom, in contrast to the total extract of P. major , where its fractions produce a greater degree of inhibition. In a previous study, total extracts of O. rosea “bloodsucker” were found to have a lower inhibitory capacity on thrombin than its fractions 27 . In addition, Genc et al 28 evaluated the inhibition values of hyaluronidase, collagenase, and elastase enzymes by the aqueous extract of P. major major and three of its fractions (F-1, F-2 and F-3); it was evidenced that the total extract produced an inhibition of hyaluronidase and collagenase of 27.0% and 21.9%, respectively, while F-1 presented greater inhibition with values of 41.6% and 28.3% on both enzymes; elastase was not inhibited neither by the total extract nor by the fractions.…”

“…En el presente trabajo se ha mostrado que el extracto total de P. aduncum tiene mayor capacidad que sus fracciones para inhibir a la PLA2 del veneno de L. muta muta , a diferencia del extracto total de P. major, donde sus fracciones producen una inhibición en mayor grado. En un estudio previo, se observó que los extractos totales de O. rosea «chupasangre» tienen una menor capacidad inhibitoria sobre la trombina que sus fracciones 27 . Además, Genc et al .…”
