Pharmacokinetic of Jiaotai pill in normal and depressed rats / 药学学报

ABSTRACT

This study was aimed to explore the pharmacokinetics of epiberberine, jatrorrhizine, coptisine, palmatine, berberine of Jiaotai pill in the normal and depressed rats. According to ‘Katz’ method, the model of chronic unpredictable mild stress (CUMS) was established. The extract of Jiaotai pill was orally administered to rats, and the blood samples were collected via the the oculi chorioideae vein according to the time schedule. The concentrations of epiberberine, jatrorrhizine, coptisine, palmatine, berberine in rat plasma were determined by LC-MS/MS, and the pharmacokinetic parameters were calculated by DAS1.0 software. Compared with normal rats, the Cmax of palmatine, coptisine, berberine and jatrorrhizine in Jiaotai pill in depressed rats were 1.99, 2.14, 2.3, 1.82 times than the normal group, while the AUC0−t were 1.23, 1.25, 1.29, 1.46 times and the AUC0−∞ were 1.21, 1.25, 1.30, 1.43 times, which were significantly different.
