RESUMO

Aim To study the absorption mechanism of apigenin-7-O-glucronide, 3,4-Dihydroxycinnamic acid and chlorogenic acid in Erigeron breviscapus extract ( Ebe) by Caco-2 cell monolayer model. Methods The three active ingredients were quantified by UPLC-MS/MS method, and the effect of Ebe concentrations, conveying times, pH values and P-glycoprotein inhibi-tor on the transport of three active ingredients were also investigated. Results Apigenin-7-O-glucronide and chlorogenic acid in Caco-2 cell monolayer model were time-dependent and concentration-dependent. The 3, 4-Dihydroxycinnamic acid in Caco-2 cell uptake was concentration-saturate and P-glycoprotein inhibitor was involved in the uptake process. Conclusion The mechanism of apigenin-7-O-glucronide and chlorogenic acid absorption in cells is mainly through passive trans-port, and the absorption of 3, 4-Dihydroxycinnamic acid is mainly realized by the carrier transport.
