β-cyclodextrin has an ability to protect compounds from oxidative reaction by collecting them within its ring-like structure. So, In harsh condition (40oC), marker compound, quercetin, was dramatically reduced in Hovenia dulcis fruit extract containing dextrin at 4 and 8 week compared to 0 week, but not that containing β-cyclodextrin. To evaluate the effects of dextrin and β-cyclodextrin on protective effect of H.dulcis fruit extract against alcohol- induced liver damage, The mice were orally injected alcohol, H. dulcis fruit extract/dextrin (HD) and H. dulcis fruit extract/β-cyclodextrin (HCD), respectively, for 7 days. The mice orally administrated with alcohol significantly enhanced the serum concentration of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and the activity of lactate dehydrogenase (LDH) in serum compared to the control group. HD and HCD significantly decreased the levels of serum ALT and AST and serum LDH activities compared to alcohol group. And also alcohol group significantly increased the level of total cholesterol compared to the control group, but HD and HCD significantly reduced it compared to the alcohol group. However, the levels of TG in blood were not significantly changed in all groups. The activities of alcohol dehydrogenase (ADH) were significantly increased in HD and HCD group although those of aldehyde dehydrogenase showed an increasing tendency. This data suggested that HD and HCD were able to induce alcohol degradation in the liver tissues. All together, the results showed that HCD demonstrated their ability to protect liver from alcohol-induced damage on equal terms with HD.
