|---|---|---|---|---|---|
| EA | 4.43 ± 0.15 a | 1.27 ± 0.06 | 127.36 ± 0.98 b | 0.97 ± 0.06 a | 15.22 ± 0.11 |
| MeOH | 4.00 ± 0.05 a | na | 136.51 ± 0.70 a | 0.68 ± 0.03 b | na |
| Water | 3.15 ± 0.02 b | na | 81.63 ± 2.10 c | 0.21 ± 0.01 c | na |
Values expressed are means ± S.D. of three parallel measurements. GALAE, galatamine equivalent; KAE, kojic acid equivalent; ACAE, acarbose equivalent; na, not active; EA, ethyl acetate; MeOH, methanol. Different letters indicate significant differences in the extracts (p < 0.05). Superscript letters (a,b,c) indicate different levels of statistical significance.
