    • note
    • A test sample (ethanol solution, 2 mL) was added to 0.5 mM DPPH in ethanol (1 mL) mixed with a 50 mM 2-monopholinoethanesulfonic acid (MES) buffer (pH 7.4, 2 mL), and the mixture was shaken vigorously and kept at 25°C for 30 min. The DPPH radical scavenging activity is expressed as the ratio of the relative decrease in the absorbance of the test sample mixture at 517 nm to that of the 1 mM butylhydroxytoluene (BHT) solution. DPPH radical scavenging activity (%)={(ethanol alone)-(test sample)}/{(ethanol alone)-(BHT)} × 100
