Abstract: The present invention relates to a catechin absorption enhancer in small intestinal epithelial cells, and more particularly, to an enhancer for improving an absorption rate of catechin in small intestinal cells and a composition including the same. The composition including the catechin absorption enhancer in the small intestinal epithelial cells according to the invention can enhance the absorption rate of catechin in the small intestinal epithelial cells, which leads to improved bioavailability. Therefore, the present invention can be expected to improve an antioxidant effect, an anti-aging effect, a lipolytic effect, and a variety of other effects of the catechin.

Abstract: Disclosed is a catechin bioavailability enhancer comprising cyclodextrin as an active ingredient. Further, disclosed is a composition comprising a catechin bioavailability enhancer comprising catechin and cyclodextrin. The composition disclosed in the present specification may improve the stability of catechin which has significantly low intestinal absorption rate, and thus may improve bioaccessibility, intestinal transport rate and bioavailability of catechin. Accordingly, the improved bioavailability may further increase the effects of catechin such as the effects of reducing weight and body fat, anti-oxidative effects and anti-aging effects. The composition disclosed in the present specification having the abovementioned characteristics can be effectively used in the fields of food or pharmacy.

Abstract: A method for preparing a Smilax china L. root extract having an increased active ingredient content, and a beverage composition for detoxification including the same are provided. The method for preparing a Smilax china L. root extract includes preparing a powder of a Smilax china L. root, obtaining an ethanol extract of Smilax china L. root from the powder of Smilax china L. root using ethanol, and concentrating the ethanol extract of Smilax china L. root under a reduced vacuum to obtain a concentrate having a reduced ethanol content.
