Abstract

In this study, increased alcohol decomposition efficacy (ADH) of Hoveina dulcis extract by Carbohydrate-Hydrolyzing Enzymes was investigated. Carbohydrate decomposition enzymes such as Maxinvert (Invertase), Optidex L-400 (Glucoamylase) and Rohament CL (Cellulase & Pectinase) were added to Hoveina dulcis extract at different concentrations (0.01, 0.05, 0.1, 0.5 and 1%) for 48 hrs, after which samples were taken every 6 hrs for determination of ADH activity. As the enzyme concentration became higher, ADH activity also increased. Especially, the addition of 1% Rohament CL increased enzyme activity to 76% at 30 hrs incubation, after which the increase in activity stopped. In the rat and human body experiment, enzymatic decomposition of Hovenia dulcis extract by addition of 1% Rohament CL was also effective in decreasing serum alcohol concentration and respiration. Especially, in the early stage after alcohol consumption, the efficacy of enzyme treatment of Hovenia dulcis extract was more effective. These results show that if the glycoside forms of active compounds such as flavonols in Hovenia dulcis extract are converted into aglycone forms, alcohol decomposition capability can be enhanced.

본 연구에서는 헛개나무 열매 추출물을 당 분해효소를 이용하여 효소처리 시 알코올 분해능에 미치는 영향을 알아보았다. 당분해효소인 Maxinvert(invertase), Optidex L-400(glucoamylase), Rohament CL(cellulase & pectinase)를 각각 농도별(0.01, 0.05, 0.1, 0,5, 1%)로 첨가하여 48시간 효소처리 하면서 6시간 간격으로 sample을 채취해 ADH 효소 활성을 측정하였다. 효소 농도가 높을수록 효소 활성이 증가하였으며, 시간이 지남에 따라 활성이 높아졌다. Maxinvert 효소 처리 시 기존의 활성보다 약 10% 증가하여 가장 낮은 활성 증가를 보였고, Rohament CL 효소를 1% 첨가하여 효소처리할 경우, 기존의 활성에 비해 효소 활성이 67% 증가한 것으로 가장 많은 효소 활성 증가를 보였다. Rohament CL 효소를 1% 첨가할 경우, 시간이 지남에 따라 활성이 증가하다가 30시간대부터 활성의 증가가 변화가 거의 없었다. 이로 보아 36시간까지 효소처리하는 것이 가장 효율적일 것이라 사료된다. Rohament CL 효소 1% 첨가하여 36시간 효소 처리한 헛개나무 열매 추출물을 이용하여 동물 실험 및 임상 실험을 실시한 결과, control군 및 헛개나무 열매 추출물 군에 비해 알코올 농도가 줄어드는 것을 볼 수 있었으며, 특히 알코올 섭취 초기에 그 효과가 가장 뛰어난 것으로 나타났다. 이로 보아 효소 처리한 헛개나무 열매 추출물이 기존의 헛개나무 열매 추출물에 비해 더 많은 체내 알코올 농도 감소를 나타낼 것으로 생각되며, 음주 초기에 더 많은 영향을 줄 것으로 사료되어 진다. 이는 기존의 배당체(glycoside) 형태로 존재하던 생리활성 물질이 당 분해 효소에 의해 당이 분해된 무배당체(aglycone) 형태로 전환되어 그 활성이 높아졌기 때문으로 사료되어진다.
