Abstract
|
|
|
|
Physiological properties of Sarcodon aspratus extracts were investigated. Yields of water, 30, 60, and 90% ethanolic extracts were 52.10, 46.90, 41.50, and 32.20%, respectively. The 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of 60% ethanolic extract was 40.40% at a concentration of 4 mg/mL, which was highest of all the extracts. The polyphenol content of 60% ethanolic extract was the highest at 16.23 mg/g at a concentration of 1 mg/mL. Superoxide anion radical scavenging activities were 56.30～77.05% at concentrations of 1, 2, and 4 mg/mL, which were better than the ascorbic acid activity (56.19% at 10 mg/mL) (P<0.05). Nitrite-scavenging ability was the most effective in 30% ethanolic extract. A pH level of 3.0 was the most effective for all extracts. Angiotensin-converting enzyme inhibitory activities of Sarcodon aspratus extracts were from 52.67 to 89.52%.
