In our previous studies, it was found that there existed pharmacokinetic interactions between magnoflorine and the rest of the ingredients in Coptidis Rhizoma. In this study, the pharmacokinetic interaction mechanism of magnoflorine with the rest of the components in Coptidis Rhizoma was researched based on the intestinal absorption and metabolism characteristics.The absorption characteristics of magnoflorine in each rat intestinal segments were evaluated by non-everted intestinal sac model. To identify the metabolites of magnoflorine, the acceptor solutions of each intestinal segment at 120 min were analyzed by HPLC-LTQ-Orbitrap MS.The accumulative absorption (Q), the absorption rate (J) and the apparent permeability coefficient (PIt was shown that the rest of the ingredients in Coptidis Rhizoma accelerated the absorption of magnoflorine weakly and promoted the metabolism of magnoflorine in the gut. The effects of other processes in the pharmacokinetics should be further evaluated.
