We collected wild mushroom, Sarcodon aspratus from Deogyu Mt. of Muju, Jeollabuk-do and physiological functionalities of its water extract were investigated. The water extracts from S. aspratus showed the highest antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity of 74.3% and also showed high anti-gout xanthine oxidase (XOD) inhibitory activity (59.6%). However, tyrosinase inhibitory activity was very low (17.3%), and antioxidant activity and SOD-likely activity were not detected. The ACE inhibitory activity of S. aspratus fruiting body was the highest when powder of the fruiting body was shaked at $30^{\circ}C$ for 24 h by distilled water. Furthermore, the XOD inhibitory activity was also the highest by extraction at $50^{\circ}C$ for 24 h with water.

This study was designed to extracts from Orostachys japonicas were investigated to assess anti-oxidation and biological activity. Phenolic content was maximum of $10.56{\pm}0.32mg/g$ when extracted with 50% ethanol. In anti-oxidative activity, Orostachys japonicus electric donating activity was higher than 80% in both water and ethanol extract at $200{\mu}g/mL$. 2,2'-Azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical cation decolorization of both water and ethanol extract was higher than 95.0% but antioxidant protection factor of water extract was higher than ethanol extract. Thiobarbituric acid reactive substance of ethanol extract was higher than water extract. For antihypertensive effect determination, angiotesin converting enzyme of water and ethanol extract showed 6.67 and 7.98% each at $200{\mu}g/mL$. Ethanol extract of $200{\mu}g/mL$ showed xanthin oxidase inhibitory effect of 60.85% but was not shown with water extract. Orostachys japonicus ethanol extract showed higher tyrosinase inhibitory activity of 64.59% which was higher than kojic acid of control indicating higher whitening effect. In anti-wrinkle effect, ethanol extract at $50-200{\mu}g/mL$ showed collagenase inhibitory effect of 75.95-85.02% which was higher than 68.91-76.64% of epigallocatechin-gallate of control group. 50% ethanol extract showed higher elastase inhibitory activity than water extract. Therefore, Orostachys japonicus extracts were identified to have high anti-wrinkle effect. These results identify anti-oxidative activity, gout prevention, whitening effect, and anti-wrinkle effect which indicate the possibility as a source for functional material.
