To consider potentially new sources which have hypoglycemic effect and accelerating alcohol detoxification, this study was designed to investigate the effect of Crataegus fructus and Morns alba L. in alcohol-treated rats. I compared the body weight, glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alcohol dehydrogenase (ADH), and aldehyde dehydrogenase (ALDH) of rats administered both alcohol and extract of experimental plants to rats treated with alcohol alone. Administration of extracts of C. fructus and M alba, respectively, resulted in a significant reduction in the blood glucose level and the activities of ADH of liver compared to the control rats, and administration of extract of M. alba showed significantly lower on bodyweight gain in the rats than in other treated rats. In contrast, the activities of ALDH of liver were increased. The activities of AST and ALT between the only alcohol-treated rats and the alcohol and experimental plants-treated rats were no significant difference. The results suggest that C. fructus and M alba have a hypoglycemic effect, and reduce liver damage by accelerating acetaldehyde metabolism in alcoholic rats, so the combined effect of C. fructus and M alba may be considered as an alternative remedy for hangovers, alcohol-induced overweight and alcohol-induced diabetes.

The methanolic extract of the root-bark of Morus alba L.(Mulberry tree) has the potent antibacterial activity against Streptococcus mutans. Its active component was identified to be sanggenon C. The active component had stronger anti-bacterial activity than berberine, having minimum inhibitory concentration(MIC) of $25\;{\mu}g/ml$. Moreover, the inhibitory effect of this component on the cellular adherence of Streptococcus mutans to glass surfaces also was more remarkable than that of berberine in the presence of glucosyltransferase(GTase) and sucrose in vitro. These results indicate that sanggenon C may play an important role in inhibiting plaque formation and caries incidence.
