| Sample | Solvent | Total polyphenol contents (mg GAE/g of extract)1) | Total flavonoids contents (mg CE/g of extract)2) |
| AG | Hot water | 3.46±0.08b3) | 8.51±0.37c |
| 70% ethanol | 3.54±0.06b | 25.04±0.62b |
| 100% ethanol | 4.50±0.12a | 41.08±1.18a |
| DAG | Hot water | 3.97±0.15b | 26.51±0.92b |
| 70% ethanol | 4.19±0.03a | 27.04±0.40b |
| 100% ethanol | 3.98±0.08b | 39.60±0.81a |
Total polyphenol contents are expressed as gallic acid equivalents (GAE).
Total flavonoids contents are expressed as catechin equivalents (CE).
Means with different superscript letters in the same column are significantly different at p<0.05 by Duncan’s multiple range test (a>b>c).
