ABSTRACT
Objective:
Based on the tumor-bearing rat model, using rutin, quercitrin, and isoquercitrin from Hedyotis diffusa as the research object, the pharmacokinetics of those three flavonoid glycosides in the pathological state was studied.Methods:
Establishing a method for the comparison of the pharmacokinetics of flavonoid extracts in normal rats and tumor-bearing rats, which was analyzed by HPLC-MS/MS in subcutaneous tumor models of SD rat made with tumour cell of Walker-256.Results:
Compared with the pharmacokinetics parameters of flavonoid glycosides in normal rats, the Cmax and AUC0-∞ of rutin, quercetin, and isoquercitrin in the tumor-bearing rats were significantly decreased, t1/2z was prolonged, and the metabolic time of three components was prolonged to 24 h, which revealed the effect of pathological condition on the pharmacokinetic characteristics of flavonoid glycosides.Conclusion:
The method established in this study is simple, fast, sensitive, and suitable for the pharmacokinetic study of flavonoid glycosides in rats in vivo. The pharmacokinetic characteristics of flavonoids in normal and tumor-bearing rats are different.
