Summary:Response surface methodology (RSM) was used to optimize extraction conditions of Pleurotus cornocopiae. Coefficients of determination (R2) for dependent variables ranged from 0.86 at 0.91. Maximum extraction yield was 40.81% under the following conditions: microwave power of 60.08 watts, ethanolic concentration of 12.33%, and extraction time of 6.86 min. Maximum extraction electron donating ability was 35.72% at 44.13 watts, 19.30%, and 4.21 min. Maximum extraction superoxide dismutase (SOD)-like activity was 34.87% at 114.01 watts, 65.88%, and 1.56 min. Maximum extraction total polyphenol content was 31.77 mg/g at 50.52 watts, 23.00% and 2.90 min. Based on the superimposition of four dimensional RSM with respect to extraction yield, electron donating ability, SOD-like activity, and total polyphenol content obtained under various extraction conditions, the optimum ranges of extraction conditions were as follows: microwave power of 71.48~92.84 watts, ethanol concentration of 55.01~71.66%, and extraction time of 3~9 min. 노랑느타리버섯의 항산화 활성을 측정하여 효율적 추출조건을 예측하기 위해 마이크로웨이브 에너지, 에탄올 농도, 추출시간의 요인변수를 중심합성법에 따라 설정하여 반응 표면분석을 통해 최적화 조건을 설정하였다. 노랑느타리버섯 추출물의 수율, 전자공여작용, SOD 유사 활성, 총 폴리페놀 함량에 대한 반응표면의 회귀식 $R^2$ 값이 각각 0.91, 0.87, 0.86 및 0.87로 분석되었고, 수율은 P<0.01, 항산화 활성이 P<0.05에서 유의적 수준을 나타냈다. 노랑느타리버섯은 요인변수에 따라 수율, 전자공여작용, 총 폴리페놀 함량의 경우 마이크로웨이브 에너지의 영향을 가장 많이 받았고, SOD 유사 활성의 경우 에탄올 농도에 따른 유의적 차이를 보였다. 추출물의 각 특성을 모두 만족시키는 최적의 추출조건의 범위는 superimposing 하여 마이크로웨이브 에너지 71.48~92.84 watts, 에탄올 농도 55.01~71.66%, 추출시간 3~9분으로 예측되었다.
