Brazil-cherry leaves (Eugenia uniflora L.) have antioxidant activity because they contain phenolic and flavonoids compounds. The aim of the study was to obtain antioxidant activity using FRAP (Ferric Reducing Antioxidant Power) method. Brazil-cherry leaves were extracted using soxhlet method by ethanol 70%. The free radical activity absorbance was measured with a UV-Vis spectrophotometer at a wavelength of 711 nm and the total value of antioxidant activity was calculated based on the data absorbance. The results showed that Brazil-cherry leaves have the antioxidant activity with the value 2.493mgAAE/g extract. [ABSTRACT FROM AUTHOR] |
