[Pharmacokinetics of five ginsenosides of Shexiang Baoxin pill in plasma of myocardial infarction rats]

Shexiang Baoxin pill(SBP) is widely used for treating coronary heart disease in clinic, with ginsenosides as its main effective component. This study was designed to investigate and compare the pharmacokinetic characteristics of five ginsenosides of five compounds after multiple oral administrations, ginseng extract(GE) and SBP in myocardial infarction rats. After intragastric administration to myocardial infarction rats, the plasma samples were analyzed by liquid chromatography tandem triple-quad mass spectrometry. The results showed that Cmax of five compounds in all groups were less than 200 μg•L⁻¹. Tmax of corresponding analytes between groups revealed that ginsenosides in both SBP and GE were absorbed faster than each of the five compounds, indicating that GE and compounds contain components promoting absorption of ginsenosides. The oral administration doses of ginsenosides in SBP were the least in all groups, but with the greatest AUC0-tand AUCINF, which indicated that ginsenosides in SBP had the best absorption in all groups after oral administration to myocardial infarction rats. This study also demonstrated that compound is the best form of traditional Chinese medicine.
