Effect of Berbamine Hydrochloride on Intestinal Absorption Characteristics of Berberine Hydrochloride by Rat Everted Intestinal Sac Model / 中国实验方剂学杂志

ABSTRACT

Objective: To investigate the effect of berbamine hydrochloride on the absorption characteristics of berberine hydrochloride in different intestinal segments of rats in normal environment and high calcium environment. Method: Taking rat everted intestinal sac model,the content of berberine hydrochloride in absorbent solution of everted intestinal sac from different compatibility groups was determined by HPLC,and the uptake per unit area in different groups was analyzed by One-way ANOVA. Result: Compared with the normal J70 group(in normal environment,the concentration of berberine hydrochloride was 70 mg·L-1) at the same time point,the uptake per unit area of the normal J70+Ver100 group(in normal environment,the concentration of berberine hydrochloride was 70 mg·L-1,adding verapamil hydrochloride to a concentration of 100 mg·L-1) was significantly increased in the ileum(P-1,adding berbamine hydrochloride to a concentration of 35 mg·L-1) were significantly increased in the duodenum(P-1,adding berbamine hydrochloride to a concentration of 70 mg·L-1) were significantly increased in the ileum(PConclusion: Berbamine hydrochloride can promote the absorption of berberine hydrochloride in intestine to a certain extent,especially in the high calcium environment.
