IC50 values of SIF on rat α-glucosidase in vitro
| Component | IC50 (g/L) |
||
|---|---|---|---|
| Total α-glucosidase (Km = 0.7 mM) | Maltase (Km = 1.7 mM) | Sucrase (Km = 21.2 mM) | |
| F30 | >10 | 9.4 | 8.8 |
| SIF | 3.1 | 5.6 | 8.6 |
| Daidzein | 2.52 | 4.7 | 8.5 |
| Genistein | 2.39 | 3.9 | 9.4 |
| Glycitein | 8.8 | 8 | >10 |
| ACR | 0.12 | 0.19 | 0.34 |
Km values were obtained from Lineweaver-Burk plots of rat α-glucosidase. The results represent the means of four experiments.
