The bioactive compounds and antioxidant activity of ethanol and ethyl ecetate extracts of Candi Banana (Musa paradisiaca)

[摘要] Banana has various benefits for health. One local variety of banana is candi banana (Musa paradisiaca). The aim of this research was to study the content of the bioactive compounds of phenolics, flavonoids, tannin, carotenoids and the antioxidant activity of extract ethanol and ethyl acetate of candi banana. Powdered candi banana was extracted using ethanol and ethyl acetate in an ultrasonic bath. The results showed that the content of phenolics, flavonoids, tannin and carotenoids in ethanol extract were 58.76 ± 3.19 mg/kg, 416.08 ± 18.79 mg/kg, 209.83 ± 15.87 mg/kg and 74.55 ± 4.31 mg/kg, respectively. The content of phenolics, flavonoids, tannin and carotenoids in ethyl acetate extract were 0.83 ± 0.12 mg/kg, 4.31 ± 0.66 mg/kg, 49.97 ± 2.43 mg/kg and 304.40 ± 16.62 mg/kg. While the antioxidant activity (IC50) of ethanol extract and ethyl acetate were 3374.13 ± 123.46 ppm and 40318.19 ± 1014.90 ppm. This research showed that type of solvents of ethanol and ethyl acetate affected the content of bioactive compounds and antioxidant activity of candi banana. The antioxidant activity of ethanol extract was higher than that of ethyl acetate extract. It showed that ethanol was a better solvent than ethyl acetate to extract bioactive compounds in candi banana.
