Ehretia asperula is a widely used as a medicinal plant in Vietnam. In the present study, leaves of Ehretia asperula grown in Tay Ninh province were selected to evaluate their potential as antioxidant and antibacterial agents. The antioxidant activities were determined by total antioxidant capacity, reducing power, neutralize free radicals 2,2-diphenyl-1-picrylhydrazyl and 2,2’-azino-bis(3-ethylbenzothiazoline6-sulfonic aicd). The antibacterial activity was determined by determining the antibacterial ring diameter, the minimum inhibitory concentration and the minimum bactericidal concentration of four strains of Gram-negative bacteria and two strains of Gram-positive bacteria. The ethyl acetate fraction of Ehretia asperula leaves had stronger antioxidant activity than the other extracts with EC50 values ranging from 10 to 20 µg/mL. Ehretia asperula leaf extracts were more effective against Gram-positive bacteria than Gram-negative bacteria. The results show that there is a direct correlation between polyphenol content, antioxidant activity and antibacterial activity. Thus, the leaves of Ehretia asperulagrown in Tay Ninh showed good antioxidant and antibacterial activities.
