Study on the Alleviation of an Alcohol Induced Hangover and the Antioxidant Activity by Mulberry Fruit

오디 추출물의 알코올 분해능 및 항산화 효과

This study investigated the effects of mulberry fruit extract on antioxidant activities and the alleviation of an alcoholinduced hangover, which was measured with alcohol dehydrogenase(ADH) enzyme activity. The antioxidative capacity of each mulberry extract was measured by total phenolic compounds, electron donating ability, superoxide dismutase-like ability, thiobarbituric acid reactive substances, and nitrite scavenging ability. The 60% methanol extract yielded the highest total phenolic compounds. The electron donating ability of the 40% ethanol and 40% methanol extracts were 68% and 67%, respectively. The superoxide dismutase-like abilities of the 40% methanol and 40% ethanol extracts were 30% and 28%, respectively, when extracts were assayed at 2.5 mg/$m\ell$. The nitrite scavenging ability of the 60% ethanol and 40% methanol extracts were 98% and 97%, respectively. The 60% ethanol extract yielded the highest ADH.

본 연구에서는 식용 가능한 오디를 용매별로 추출하여 항산화 효과 및 숙취 해소 활성능을 알아보고자 하였다. 오디Fig. 1. Contents of ADH ability of each solvent fraction of mulberry fruit extract. 추출물에 들어있는 총 페놀 함량을 정량하였으며, 오디 추출물의 전자공여능, SOD 유사 활성, TBARS 아질산염 소거능 등을 통하여 오디의 항산화 활성을 측정하였고, 알코올 분해능은 alcohol dehydrogenase activity assay 방법을 이용하여 조사하였다. 오디 추출물의 총 페놀 화합물은 60% methanol 추출물에서 가장 높게 나타났다. 전자공여능(EDA)은 오디의 40% ethanol 추출물에서 BHT와 유사한 활성을 나타났고, SOD 유사 활성은 BHT보다 오디 추출물이 낮은 활성을 나타내었다. 아질산염 소거능은 오디의 60% ethanol과 40% methanol 추출물이 각각 98%, 97%로 ascorbic acid와 상응하는 결과를 보였다. 알코올 분해능에서는 오디의 60% ethanol 추출물이 가장 높은 활성을 나타내었다.
