| Methanol | 4.37 ± 0.17∗∗∗ | >75 |
| Hexane | 5.49 ± 0.01∗∗∗ | >75 |
| Chloroform | 10.50 ± 0.23ns | >87 |
| Ethyl acetate | 5.18 ± 0.01∗∗∗ | >75 |
| Epigallocatechin gallate | 10.34 ± 0.21 | >87 |
Data are expressed as mean ± SD, n = 3. Data represent a significant difference at (∗∗∗) p value < 0.05, among different solvent fractions compared with the positive control (EGCG), using one-way ANOVA, followed by Dunnett's test.
