This study aimed to investigate the biological and antibacterial activities of phenolics from Sambucus sieboldiana var. pendula leaf extract. The phenolic contents of the S. sieboldiana var. pendula extracted with water and ethanol was 11.60 and 12.39 mg/g, respectively. The inhibitory effects of the water and ethanol extracts on the angiotensin converting enzyme (ACE) were 71.94-92.08 and 48.42-78.33%, respectively, and on xanthine oxidase (XOase) were 42.11-100 and 35.61-100%, respectively, at a phenolic concentration of 50-200 ㎍/mL. All these effects were found to be concentration-dependent. Additionally, the leaf extracts exhibited excellent antibacterial activities against Streptococcus mutans, Staphylococcus aureus, and Propionibacterium acnes. Hence, S. sieboldiana var. pendula was confirmed to have excellent antihypertensive, antigout, and antimicrobial properties.

In order to apply into functional food or medicinal industry, nutritional characteristics and physiological functionality of Hypsizygus marmoreus (brown cultivar) were investigated. Fruiting body of H. marmoreus contained 27.3% of crude protein, 55.8% of total sugar and 11,109.3 mg/100 g dry weight of malic acid. Furthermore, 66.7% of antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity and 37.3% of antigout xanthin oxidase inhibitory activity showed in the water extract from H. marmoreus. The economically ACE inhibitory activity (81.4%) was obtained when the fruiting body of Hysizygus marmoreus was extracted with distilled water of $50^{\circ}C$ for 12 h, even though maximal ACE inhibitory activity (84.4%) was showed the extracts from $70^{\circ}C$ for 12 h.

The extracted phenolic compounds from Cornus kousa fruit for biological activities as functional resources were examined. The phenolic compounds which were extracted with water and 40% ethanol from Cornus kousa fruit were $7.04{\pm}0.27$ and $4.47{\pm}0.18mg/g$, respectively. The 1,1-diphenyl-2-picrylhydrazyl free radical scavenging activity of water and ethanol extracts were 84% and 86% at $50{\mu}g/mL$phenolics, respectively. The 2,2'-Azinobis-(3-ethylbenzothiazoline-6-sulfonic acid radical decolorization activity of water and ethanol extracts were 84 and 95% at $100{\mu}g/mL$ phenolics, respectively. Antioxidant protection factor in water and ethanol extracts at $50{\mu}g/mL$ phenolics were 1.93 and 1.82 PF, respectively. Thiobarbituric acid reactive substance were 69% in water extracts and 89% in ethanol extracts at $150{\mu}g/mL$ phenolics. The inhibition activity on xanthine oxidase in water and ethanol extracts was 34 and 60%, respectively. The inhibition activity on ${\alpha}$-glucosidase was 29% in water extracts and 87% in ethanol extracts. The tyrosinase inhibitory activity was 19% in ethanol extracts. The collagenase inhibition activity of anti-wrinkle effect showed an excellent wrinkle improvement effect as 53% in water extracts and 77% in ethanol extracts at $200{\mu}g/mL$ phenolics. The hyaluronidase inhibition activity as antiinflammation effect of water extracts was confirmed to 34% of inhibition at $200{\mu}g/mL$ phenolic. The results can be expected extracts from Cornus kousa fruit to use as functional resource for antioxidant, antigout, inhibitor of carbohydrate degradation, antiwrinkle activity and antiinflammation activity.
