Abstract:
The study investigated antibacterial activity of Morinda citrifolia L. collected in Tan Hung district, Long An Province in Vietnam. Antimicrobial activity of Morinda citrifolia L. was evaluated based on size of antibacterial zones of ethanol leaf and fruit extracts by agar well diffusion method. The results showed that ethanol leaf and fruit extracts produced growth inhibition zones against tested bacteria with diameters of smaller than 9.0 mm (1.80 - 6.72 mm and 1.66 - 8.06 mm, respectively). The lowest ethanol concentration of extracts inhibited growth of tested bacteria was 200 mg mL-1 and their antibacterial activity increased with increase in tested concentrations. In general, antibacterial effects of fruit extracts were higher than those of leaf extracts on bacterial growth. Antibacterial activity of ethanol extracts of Morinda citrifolia L. leaves and fruits were evaluated at weak degrees, according to Manuanza’s rating scale of antibacterial zones.
