Sample | DPPH radical scavenging activity (μg/mL, EC50) | Total polyphenol1) contents (mg/g) |
80% methanol extract | 67.43±4.282)a3) | 16.26±1.02a |
Chloroform fraction | 5.27±1.08b | 9.07±0.38b |
n-Butanol fraction | 13.82±2.42c | 4.42±0.38c |
Aqueous fraction | 53.92±5.76d | 0.43±0.04d |
Each μg gallic acid equivalents (GAE)/g sample.
Each value expressed as the mean±SD (n=4).
Means in the same column with the different are significantly different (p<0.05) by Duncan’s multiple range test.
