Abstract:
:A sensitive and specific HPLC method was developed to analyze baicalin in rat plasma. The author had compared the pharmacokinetics of baicalin after oral administration of HLJDT decoction or pure baicalin in MCAO and sham-operated rats. All the rats were divided into two groups, MCAO and sham-operated rats. Each group contained two subgroups: HLJDT decoction and pure baicalin subgroup. The HLJDT subgroup oral administration of HLJDT decoction extract 10.00 g/kg according to body weight (containing baicalin 400.00 mg/kg according to body weight), the pure baicalin subgroup received a gavages at a dosage of baicalin 400.00 mg/kg according to body weight too. The pharmacokinetics parameters were analyzed by kinetica. The results indicated that the pharmacokinetics of baicalin in rat plasma was non-linear and there were significant differences between different groups. No matter in MCAO or sham-operated rats, pure baicalin had shown better absorption than HLJDT decoction. Whether administration of pure baicalin or HLJDT decoction, the MCAO rats show better, quicker absorption of baicalin than sham-operated rats. It was good for baicalin to exert pharmacological effects on healed cerebrovascular diseases. The method had been applied successfully to pharmacokinetics of baicalin in rat plasma after oral administration of pure baicalin or HLJDT decoction.
