Objective: To establish a UPLC-ESI-MS/MS for determining anemoside B4 in rats
through comparing the distribution of anemoside B4 in liver
spleen
kidney
heart and lung of normal rats and rats with ulcerative colitis
in order to further study on the process and mechanism of Baitouweng Tang in treating ulcerative colitis. Method: Male SD rats were divided into normal group and model group
after intragastric administration of Baitouweng Tang lyophilized powder with dose of 5 g·kg-1
normal and model rats were anesthetized with 5% chloral hydrate at 15
45
120
360 min
then to take liver
spleen
kidney
heart and lung tissue.UPLC-ESI-MS/MS was adopted with mobile phase of 0.1% formic acid aqueous solution and 0.1% formic acid acetonitrile solution for gradient elution
column temperature of 35 ℃ and flow rate of 0.4 mL·min-1. Result: Anemoside B4 was widely distributed and metabolized in rats.The concentration of anemoside B4 in liver
spleen
kidney
heart and lung of normal rats reached the maximum at 120 min.Compared with the normal group
the content of anemoside B4 in liver and heart of model group rats was significantly increased (P < 0.05) at each time point;in spleen and kidney
it increased significantly (P < 0.05) at 45 min and 120 min;in the lung
it increased significantly (P < 0.05) at 120 min. Conclusion: Absorption and bioavailability of anemoside B4 in ulcerative colitis rats are better than those of the normal group
and the pathological state of ulcerative colitis can cause absorption enhancement of anemoside B4 in Baitouweng Tang.
