Abstract

This study was conducted to investigate the physiological activities of the ethanol extracts from 10 different strains of Pholiota nameko. In addition, the ${\beta}$-glucan and polyphenol contents from these strains were also measured. Total polyphenol contents from all the strains were more than 40 mg% with the highest content of $61.50{\pm}0.59$ mg% and ${\beta}$-glucan contents were 30% with the highest content of $37.20{\pm}1.12%$. The highest inhibitory activities on ${\alpha}$-amyloglucosidase activity and nitric oxide production were $13.78{\pm}0.56%$ and $56.59{\pm}7.11%$, respectively. However, ethanol extracts from all the strains have little effects on DPPH radical and nitrite scavenging rates and the activity of angiotensin I converting enzyme. The cytotoxic activity of ethanol extracts from all the strains on A549 cell was shown upto 30% with the highest effect of $47.96{\pm}8.46%$ treated at 1 mg/mL concentration.
