Research PaperComparisons of pharmacokinetic and tissue distribution profile of four major bioactive components after oral administration of Xiang-Fu-Si-Wu Decoction effective fraction in normal and dysmenorrheal symptom rats
چکیده انگلیسی

Ethnopharmacological relevanceXiang-Fu-Si-Wu Decoction (XFSWD) has been widely used to treat primary dysmenorrhea in clinical practice for hundreds of years and shown great efficacy. One fraction of XFSWD, which was an elution product by macroporous adsorption resin from aqueous extract solution with 60% ethanol (XFSWE), showed great analgesic effect. The present study was conducted to investigate the possible pharmacokinetic and tissue distribution profiles of four major bioactive constituents (berberine, protopine, tetrahydrocoptisine and tetrahydropalmatine) after oral administration of XFSWE in dysmenorrheal symptom rats, and to compare the difference between normal and dysmenorrheal symptom rats.Materials and methodsEstradiol benzoate and oxytocin were used to produce dysmenorrheal symptom rat model. The experimental period was seven days. At the final day of experimental period, both normal and dysmenorrheal symptom rats were orally administrated with XFSWE, and then the blood and tissues samples were collected at different time points. Berberine, protopine, tetrahydrocoptisine and tetrahydropalmatine in blood and tissue samples were determined by LC-MS/MS. Pharmacokinetic parameters were calculated from the plasma concentration-time data using non-compartmental methods. The differences of pharmacokinetic parameters among groups were tested by one-way analysis of variance (ANOVA).ResultsThere were statistically significant differences (P<0.05) in Cmax, Tmax, AUC0−t, AUC0−∞, MRT0−t, MRT0−∞ and CL/F between normal and dysmenorrheal symptom rats that orally administered with same dosage of XFSWE. In tissue distribution study, the results showed that the overall trend was CSpleen>CLiver>CKidney>CUterus>CHeart>CLung>COvary>CBrain>CThymus, CM-60 min>CM-120 min>CM-30 min>CC-60 min>CC-120 min>CC-30 min. The contents of protopine in liver, spleen and uterus were more than that in other tissues of dysmenorrheal symptom rats. Compared to normal rats, partial contents of the compounds in dysmenorrheal symptom rats׳ tissues at different time points had significant difference (P<0.05).ConclusionsThis study was the first report about pharmacokinetic and tissue distribution investigation in dysmenorrheal symptom animals. The results indicated that berberine, protopine, tetrahydrocoptisine and tetrahydropalmatine have higher uptake and slower elimination in the rats with dysmenorrheal syndrome, which suggests that the rate and extent of drug metabolism were altered in dysmenorrheal syndrome rats. And the results also demonstrated that berberine, protopine and tetrahydropalmatine in normal and dysmenorrheal symptom rats had obvious differences in some organs and time points, suggesting that the blood flow and perfusion rate of the organ were altered in dysmenorrheal symptom animals.
