RESUMO

Purpose A RP-HPLC method was used to determine genioside and breviscapine in plasma and to study its pharmacokinetics in rat, respectively.Methods Rat plasma samples were collected after a single dose of Zhideng injection and pharmacokinetic parameters of genioside and breviscapine were estimated,respectively.Results A good linear relationship was obtained between 0.2-40.0 μg/mL for breviscapine, and 0.5-200.0 μg/mL for genioside.The recoveries from plasma were larger than 85%,and RSDs of inter-day asaay and intra-day assay were below 10%. The pharmacokinetic results showed that genioside and breviscapine were rapidly eliminated from plasma after iv administration of three doses of Zhideng injection.The mean half-life was 72.6 min and 21.6 min,respectively.Conclusion The established HPLC method was suitable for the pharmacokinetic study of genioside and breviscapine.
