유자씨 추출물의 항산화성분 및 항산화활성에 대한 최적 추출조건을 선정하기 위하여 추출온도($30{\sim}70^{\circ}C;\;X_1$), 추출시간($1{\sim}5$시간; $X_2$) 및 교반속도($200{\sim}600rpm;\;X_3$)를 독립 변수로 추출된 추출물의 추출수율, 총 polyphenol 함량, DPPH radical 소거활성 및 아질산염소거활성을 측정하였다. 추출수율의 최적조건은 추출온도, 추출시간 및 교반속도 각각 $50.23^{\circ}C$, 3.03시간, 400.06 rpm으로 최대 20.23%로 예측 되었으며, 총 폴리페놀 함량의 최적조건은 $49.88^{\circ}C$, 2.72시간 및 400.39 rpm으로 최대 4.37 mg/g으로 예측되었다. DPPH radical 소거활성은 각각 $50.28^{\circ}C$, 3.42시간 및 399.96 rpm으로 최대 49.69%로 예측되었으며, 아질산염소거활성은 추출온도, 추출시간 및 교반속도 각각 $49.19^{\circ}C$, 0.68시간 및 602.95 rpm으로 최대 47.79%로 예측되었다. 이상의 결과를 바탕으로 유자씨 추출물의 항산화활성을 위한 최적 조건은 추출온도, 추출시간 및 교반속도가 각각 $50^{\circ}C$, 3시간, 400 rpm로 결정하였으며, 이 조건에서 추출물을 제조하여 추출 수율, 총 폴리페놀 함량, DPPH radical 소거활성 및 아질산 염소거활성을 측정한 결과 각각 20.31%, 4.22 mg/g, 49.54% 및 44.30%로 나타났다.

Abstract

Extraction characteristics of citron (Citrus junos Sieb. ex Tanaka) seeds and functional properties of corresponding extract were monitored by response surface methodology (RSM). Maximum extraction yield of 20.23% was obtained at extraction temperature of $50.23^{\circ}C$, extraction time of 3.03 hr, and shaking velocity of 400.06 rpm. At extraction temperature, extraction time, and shaking velocity of $49.88^{\circ}C$, 2.72 hr, and 400.39 rpm, respectively, maximum polyphenol content was 4.37 mg/g. At extraction temperature, extraction time, and shaking velocity of $50.28^{\circ}C$, 3.42 hr, and 399.96 rpm, respectively, maximum electron donating ability (EDA) was 49.69%. Maximum nitrite scavenging activity (NSA) was 47.79% at extraction temperature, extraction time, and shaking velocity of $49.19^{\circ}C$, 0.68 hr, and 602.95 rpm, respectively. Based on superimposition of 3-dimensional RSM with respect to extraction yield, polyphenol, EDA, and NSA, optimum ranges of extraction conditions were extraction temperature of $50^{\circ}C$, extraction time of about 3 hr, and shaking velocity of 400 rpm.
