摘要: 在体外模拟人体消化环境,通过测定在不同pH值、离子强度、聚乙烯吡咯烷酮(PVP)和尿素浓度条件下,绿茶浸提液在体外对牛磺胆酸钠、甘氨胆酸钠、胆酸钠的结合能力,比较这些因素对绿茶浸提液结合胆酸盐的影响。结果表明,pH值、尿素浓度对绿茶浸提液结合胆酸盐有显著性影响(P≤0.05),离子强度对绿茶浸提液结合胆酸盐影响不显著(P≥0.05)。

Abstract: Through determining the binding capacity of green tea extract to sodium taurocholate, glycocholate and sodium cholate under polyvinylpyrrolidone (PVP), medium pH, ionic strength and urea in vitro, the adsorption behavior of green tea extract to bile salts were compared. The results showed that medium pH and urea concentration had significant effects on binding of green tea extract to bile salts(P≤0.05), but the effect of ionic strength was not obvious(P≥0.05). 

Key words: green tea extract, bile salts, binding, impact factor
