| AChE | BChE | TYR | |
|---|---|---|---|
| Leaves | 7005.82 ± 287.85c | 8358.87 ± 343. 57c | 1633.62 ± 62.33c |
| Peel | 653.68 ± 18.20a | 701.54 ± 65.84a | 747.46 ± 66.23b |
| Pulp | 1486.37 ± 178.69b | 1582.11 ± 185.26b | 279.99 ± 26.87a |
| Seed | 660.16 ± 21.94a | 304.86 ± 26.41a | 268.97 ± 17.75a |
| Standard | 2.20 ± 0.04 | 11.70 ± 1.09 | 49.23 ± 0.70 |
Values are expressed as means ± SE (n = 3). Values followed by different letters are significantly different at p < 0.05. The standard inhibitor was galanthamine for AChE and BChE, and kojic acid for TYR
