| Plant extracts | Acetylcholinesterase (AChE) (nmol ACh hydrolyzed/min/mg protein) |
α-esterase (α-EST) (mmol/min/mg protein) | β-esterase (β-EST) (mmol/min/mg protein) |
|---|---|---|---|
| Control | 13.68 ± 0.06a | 3.34 ± 0.08a | 4.48 ± 0.04a |
| D. stramonium | 7.33 ± 0.05ab | 1.79 ± 0.07ab | 2.40 ± 0.03ab |
| C. annuum | 10.13 ± 0.03b | 2.47 ± 0.04b | 3.32 ± 0.02b |
| N. tabacum | 5.77 ± 0.05 ab | 1.41 ± 0.07 ab | 1.89 ± 0.03 ab |
| W. somnifera | 12.88 ± 0.03b | 3.00 ± 0.04b | 3.85 ± 0.02b |
Values were calculated from three replicates and expressed as mean ± SE; a, b & c: There is no significant difference (P > 0.05) between any two means, within the same column have the same superscript letter.
