ANTIOXIDANT AND ANTIBACTERIAL ACTIVITIES OF EXTRACTS FROM SEEDS OF MUSA BALBISIANA
In this paper, some extracts from seeds of Musa balbisiana were prepared with somesolvents such as petroleum ether, ethyl acetate and buthanol. The results showed that themicrowave-assisted extraction had high yield. The buthanol and ethanol extracts showed goodantioxidant activity (using reaction with free radical DPPH, 1,1-diphenyl-2-picrylhydrazyl) withIC50 value of 182.6 and 301.8 μg/mL, respectively. The minimum inhibitory concentration MICof buthanol extract was 22.5 mg/mL with both Enterococcus faecalis and Staphylococcusaureus. Besides, the ethyl acetate extract had MIC value of 7.5 and 3.5 mg/mL for Enterococcusfaecalisand Staphylococcus aureus, respectively. From results of this study, these extracts arepromising for researches as well as applications in the future.
