Water and ethanol extracts were prepared from the haesongi mushroom (Hypsizigus marmoreus) to measure functional components. The ability of the extracts to inhibit angiotensin-converting enzyme (ACE) and their hypoglycemic effects were also determined; the latter was measured by α-amylase and glucosidase inhibition. Extraction yield, protein content, total phenol, and β-glucan in the water extracts were 55.86, 17.71, 1.89, and 21.93%, respectively. The respective values for the ethanol extracts were lower than those for water extracts. Both water and ethanol extra is showed dose-dependent ACE inhibition, the effect of the former being greater. The water extract inhibited ACE activity by 95.34%, at 40 mg/mL. The IC∧50 values of the water extracts were 63.32 and 0.41 mg/mL for α-amylase and glucosidase, respectively. Thus, the water extracts had a greater hypoglycemic effect than the ethanol extracts. From these results, water is a better solvent than ethanol to extract from the haesongi mushroom functional components that show ACE inhibition and have hypoglycemic effects.
