The binding capacity of bile salts in vitro under the conditions of the simulated human digestive environment was studied.The capacity was compared among green tea,Olong tea,Puer tea,dark tea and black tea.The correlation between tea components and the bile salts binding capability was analyzed.The results showed that there is a significant correlation between bile salts binding capacity and tea polyphenol content.The green tea exhibited the greatest binding capability with combining sodium taurocholate 40.2%,glycocholate 45.7 and sodium cholate 69.7%;next was semi-fermented(Oolong tea)and fully fermented tea(Puer tea,black tea and dark tea).The experiment showed the preliminary results that tea can effectively lower the lipids in human body.
