ABSTRACT

Vegetable extracts have become important raw materials for food, pharmaceutical and cosmetic industries because of their biological potential. The objective of this study was to assess the biological activity of vegetable oils (VOs) extracted from Annona muricata and A. cherimola. Antibacterial activity was determined by plaque microdilution. The assessment of hemolytic inhibition and morphological alterations was performed in erythrocyte cultures by spectrophotometry and microscopy, respectively. Neutrophils were used to analyze both cytotoxicity by the trypan blue exclusion method and the effect on gelatinase granule release (MMP9) via zymography. Whereas VOs showed a mild antibacterial activity (900 µL/mL) on five ATCC bacterial strains, they had no effect on multi-resistant bacteria. In addition, VOs inhibited hydrogen peroxide induced hemolysis and did not cause erythrocyte cell abnormalities. Cytotoxicity was not detected in neutrophils and VOs were able to stimulate MMP9 release. These results support their potential use by the food and cosmetic industries due to their antioxidant, non-cytotoxic, and slight antibacterial capacities.


Los extractos vegetales adquieren importancia en la industria alimentaria, farmacéutica y cosmética, por su potencial biológico. El objetivo de este estudio fue evaluar actividad biológica de los Aceites Vegetales (AV) de semillas de Annona muricata y A. cherimola. La actividad antibacteriana se determinó mediante microdilución en placa; en cultivo de eritrocitos se evaluó inhibición hemolítica por espectrofotometría y alteraciones morfológicas por recuento microscópico; en neutrófilos se evaluó citotoxicidad por método de exclusión con azul de tripán, y el efecto sobre liberación de gránulos de gelatinasa (MMP9) mediante zimografía. Los AV presentaron actividad antibacteriana leve (900 µL/mL) en cinco cepas ATCC, pero no en bacterias multirresistentes; inhibieron la hemolisis inducida por peróxido de hidrogeno; no generaron deformaciones eritrocitarias; no se evidenció citotoxicidad en neutrófilos y estimularon la liberación de MMP9. Los resultados podrían sustentar el uso potencial de estos AV en la industria alimenticia o cosmética, gracias a su capacidad antioxidante, no citotóxica y levemente antibacteriana.
