Tea catechins are known to be epimerized by heat treatment. The effect of heat-epimerized tea catechins on serum cholesterol concentration was compared with that of green tea catechins. Our observations strongly suggest that both tea catechins and heat-epimerized tea catechins lower serum cholesterol concentration by inhibiting cholesterol absorption in the intestine. There was no differential effect between the two catechin preparations.
已知茶儿茶素会因热处理而发生差向异构化。将热差向异构化茶儿茶素对血清胆固醇浓度的影响与绿茶儿茶素的影响进行了比较。我们的观察结果有力地表明，茶儿茶素和热差向异构化茶儿茶素均通过抑制肠道内胆固醇的吸收来降低血清胆固醇浓度。两种儿茶素制剂之间没有差异效应。
