Which enzyme showed significantly stronger inhibitory activity (IC50 of $0.41 ext{ mg/mL}$) in ethanolic extracts compared to $\alpha$-amylase ($8.93 ext{ mg/mL}$)?
Answer
$\alpha$-glucosidase
Aqueous extracts showed high inhibitory activity against $\alpha$-glucosidase at a low IC50 value, while only exhibiting moderate activity against $\alpha$-amylase, suggesting a powerful effect by slowing carbohydrate digestion in the small intestine.
