ANTIOXIDANT AND ANTIBACTERIAL ACTIVITIES OF EXTRACTS FROM SEEDS OF MUSA BALBISIANA
Keywords:seeds of Hot banana, Musa balbisiana, antioxidant, IC50, antibacteria, MIC.
In this paper, some extracts from seeds of Musa balbisiana were prepared with some
solvents such as petroleum ether, ethyl acetate and buthanol. The results showed that the
microwave-assisted extraction had high yield. The buthanol and ethanol extracts showed good
antioxidant activity (using reaction with free radical DPPH, 1,1-diphenyl-2-picrylhydrazyl) with
IC50 value of 182.6 and 301.8 μg/mL, respectively. The minimum inhibitory concentration MIC
of buthanol extract was 22.5 mg/mL with both Enterococcus faecalis and Staphylococcus
aureus. Besides, the ethyl acetate extract had MIC value of 7.5 and 3.5 mg/mL for Enterococcus
faecalisand Staphylococcus aureus, respectively. From results of this study, these extracts are
promising for researches as well as applications in the future.
