The phenolic compounds which were extracted with 70% ethanol from Ulmus pumila for 12 hr were the highest as 17.9±1.0 mg/g. DPPH scavenging activity of 70% ethanol extracts was also the highest as 89.5±1.9% and it was confirmed to be high as 80% over in both of water and 70% ethanol extracts containing 50 μg/mL over phenolic concentration. ABTS radical cation decolorization activities of water and 70% ethanol extracts were higher as 96.8±2.9%, antioxidant protection factor (PF) was 2.0 PF in 70% ethanol and showed higher activities in both of water and 70% ethanol extracts containing 200 μg/mL phenolic concentration as 2.5 PF than BHA. TBARs of 70% ethanol extracts was 86.5±4.6%, it showed high anti-oxidative activity in 50∼200 μg/mL phenolic concentrations of water and 70% ethanol extracts as 80% over. The angiotensin converting enzyme (ACE) inhibitory activity of Ulmus pumila extracts against hypertension was 77.4% and 90.6% in water and 70% ethanol extracts of 200 μg/mL phenolic concentration. Xanthine oxidase inhibitory activity of Ulmus pumila extracts for anti-gout effect was not observed in water extracts, but it showed 30% inhibitory activity in 70% ethanol extracts, and 48.1% at 200 μg/mL phenolics concentration.

This study was carried out to determine the biological activity of Acanthopanax sessiliflorum fruit extracts. The phenolic compound contents of the extracts were 21.4 and 15.8 mg/g in hot water and 60% ethanol extracts. The total anti-oxidant activities of the water and the 60% ethanol extracts at a 200 μg/mL phenolic concent ration were at 92.4±0.8 and 89.2±1.1% in terms of the DPPH radical scavenging activity, 98.3±1.1 and 96.5±3.5% in terms of the ABTS radical decolorization, 2.0±0.6 and 1.2±2.8 PF in terms of the anti-oxidant protection factor, and 66.3±0.8 and 61.4±2.3% in terms of the TBARs inhibitory activity. The activities that inhibited the angiotensin-converting enzyme and xanthin oxidase were at 85.1±3.2 and 0% in the water extracts and 59.3±1.5 and 9.5±0.8% in the 60% ethanol extracts at the 200 μg/mL phenolic concentration. The tyrosinase and elastase inhibitory activities were at 56.6±1.8 and 53.1±1.1% in the water extracts and 33.7±2.2 and 22.4±3.1% in the 60% ethanol extracts. The astringent effect of the water and the 60% ethanol extracts were at 50.5±0.9 and 11.5±4.1%.

자색 고구마로부터 페놀성 화합물 추출 최적 조건은 50% 에탄올로 12시간 추출하였을 때 최대 용출량을 나타내었다. 불과 50% 에탄올을 용매로 하여 제조한 자색 고구마 종류별 추출물의 항산화 활성 측정 결과 전자공여능, ABTS, PF 측정에서 일반 고구마에 비하여 자색 고구마 자미, 신자미, 연자미 품종 모두 높게 나타났으며, TBARs 측정결과 모든 추출물에서 30% 이하로 낮은 TBARs 생성 억제활성을 나타내었다. 피부상재균에 대한 최소
