상황버섯을 에탄올 농도별로 추출하여 항산화 효과와 생리활성을 측정해 보았다. 농도별로 추출한 상황버섯의 페놀 함량은 추출에탄올 농도가 짙어질수록 페놀함량이 높게 나타났으며 그 중 80%에탄올 추출물에서 28.36mg/100ml로 가장 높게 나타났다. 상황버섯 추출물의 수용성물질에 대한 항산화 효과는 DPPH radical소거활성이 전체적으로 80%가 넘는 높은 저해율을 나타났고, 80% 및 90%에탄올추출물에서는 각각 94.12, 94.14%로 가장 높은 저해율을 나타내었으며, ABTS radical cation decolorization에서는 80% 에탄올 추출물에서 96.02%로 가장 높은 저해율을 나타내었다. 지용성물질에 대한 항산화효과는 antioxidant protection factor(PF)는 80% 에탄올 추출물에서 1.69로 가장 높게 나타났으며, TBARS는 80%, 90%에탄올 추출물에서 $1.15{ imes}100{mu}M,;1.21{ imes}100{mu}M$로 대조구인 $1.95{ imes}100{mu}M$보다 낮게 나와 산화촉진인자를 binding하는 능력이 좋은 것으로 나타났다. 고혈압에 관여하는 angiotensin converting enzyme과 gout에 관여하는 xanthine oxidase의 저해효과에서는 80% 에탄올 추출물에서 각각 95.10, 85.07%로 높은 저해율을 나타내었다. 농도별로 추출한 상황버섯을 HPLC로 분석한 결과 protocatecuic acid가 가장 많이 검출되었으며, 이외에도 cafferic acid, coumaric aicd 가 존재하는 것으로 나타났다.
The biological and antioxidative activity of Phellinus linteus extracts from gradient ethanol concentrations were examined. The phenol contents of Phellinus linteus(28.36 mg/100 ml) was higher in the 80% ethanol extracts than other extracts. Electron donation ability on DPPH of 80% and 90% ethanol extracts(94.12% and 94.14% inhibition) from Phellinus linteus were the highest. The antioxidant activity against water soluble materials of Phellinus linteus ethanol extracts showed totally high inhibition rates above 80%, especially in 80% and 90% ethanol extracts, they showed each 94.12% inhibition and 94.14% inhibition. The inhibition against ABTS [2,2azinobis(3-ethylbenzothiazoline-6-sulfonic acid)] radical decolorization of 80% ethanol extracts was the highest as 96.2%. The antioxidant protection factor (PF) against lipid soluble materials was the highest in 80% ethanol extracts as 1.69 PF, and TBARS of 80% and 90% ethanol extracts were lower as $1.15{ imes}100{mu}M$ and $1.21{ imes}100{mu}M$ than control($1.95{ imes}100{mu}M$. Angiotensin converting enzyme and xanthine oxidase inhibitory activity of 80% ethanol extracts from Phellinus linteus was higher as 95.10%, 85.07% than other extracts. The results to analized of simple phenolic compounds of Phellinus linteus ethanol extrcts with HPLC showed that they were procatecuic acid, caffeic acid and coumaric acid.
