Antidiabetic activity of stir-fried or steamed Chinese cabbage and nightshade leaf extracts as determined by α-glucosidase inhibition assay.
| Sample | IC50 α-glucosidase (μg ml−1) |
|---|---|
| Acarbose (positive control) | 69.83 ± 0.02b |
| Chinese cabbage | |
| Stir fried | 36.50 ± 0.06b |
| Steamed | 40.60 ± 0.14c |
| Nightshade | |
| Stir fried | 26.38 ± 0.20b |
| Steamed | 38.90 ± 0.18a |
Each value is expressed as mean ± SD in triplicate experiments. Values are mean ± SD (n = 3). Mean values with different letters are significantly different at p < 0.05 level. The IC50 values were measured as the concentration of the test sample required to inhibit the activity by 50% under assayed condition.
