[Absorption characteristics of 5 components of Xinshao extract in Caco-2 cells].

To study the absorption characteristics of Xinshao extracts in Caco-2 cells. In this paper, human colon adenocarcinoma cell line Caco-2 cell model was established, and UPLC-MS method was applied to determinate the contents of five components of Xinshao extracts(albiflorin, gallic acid, caffeic acid, scutellarin and apigenin-7-O-glucronide) in cell lysates. This model was also used to study the effect of different drug concentrations, pH, time and temperature on the absorption of five components, investigate the transport of the five components of Xinshao extracts under the conditions with or without P-glycoprotein inhibitors, and predict the absorption mechanism of these five components in Caco-2 cells.
