Inhibitory activities of S. aurita constituents on alpha-glucosidase and alpha-amylase.
| Items | Alpha-Glucosidase IC50 (µg/mL) |
Alpha-Amylase IC50 (µg/mL) |
|---|---|---|
| Carnosol | 51.8 ± 1.9 | 19.8 ± 1.4 |
| Rosmanol | 16.4 ± 1.4 | 40.9 ± 1.2 |
| 7-methoxyrosmanol | 4.2 ± 0.7 | NA |
| 12-methoxycarnosic acid | 36.9 ± 2.1 | 16.2 ± 0.3 |
| 4,7-dimethylapigenin ether | 28.7 ± 0.9 | NA |
| Crude extract | 241.9 ± 2.7 | NA |
| Acarbose | 610.4 ± 1.0 | 10.2 ± 0.6 |
The results are expressed as mean ± SD for n = 3. Acarbose is used as standard for the experiments. NA: not active within the evaluated concentrations.
