Abstract

This work was a method that used an acid hydrolysis for increasing the efficacy of decreasing alcohol concentration from Hovenia dulcis extract. For acid hydrolysis, the best pH was 2.0 to obtain a maximum alcohol dehydrogenase activity at fixed reaction temperature and time. At pH 2.0, reaction temperature $80^{\circ}C$ and reaction time 4 hr gave the highest activity which was $124\%$ of control. The bioactive compound, (+)-dihydromyricetin, content increased to $30\%$ after acid hydrolysis. This is very simple and efficient method to increase the efficacy of decreasing alcohol concentration from Hovenia dulcis extract.

본 연구는 헛개열매 추출물의 pH를 산성으로 조절한 산 가수분해 방법에 의하여 헛개열매 추출물에 배당체 형태로 존재하는 알코올분해 효능을 가진 생리활성물질 ((+)-dihydromyricetin)의 양을 증가시켰다. 반응온도 $80^{\circ}C$, 반응시간 4hr, 반응 pH 2.0에서 $124\%$의 알코올분해 효능이 증가하여 최적임을 알 수 있었다. 산 가수분해 전 후에 생리활성물질인 (+)-dihydromyricetin의 양이 $30\%$ 증가함을 알 수 있었으며, 또한 헛개열매 추출물에 포함되어 있는 고분자 물질이 분해됨을 확인할 수 있었다.
