摘要
目的:通过检测给药后家兔血浆中阿魏酸的含量,比较川芎微乳及其水煎液的生物利用度差异。方法采用RP-HPLC法,测定给药后不同时段家兔血浆内阿魏酸的含量,采用3p87软件进行药动学参数模拟。结果川芎微乳和水煎液药代动力学参数如下,微乳:AUC0-9=2123.6μg/(ml·min), Cmax=5.086μg/ml,Tpeak=56.26 min;水煎液:AUC0-9=878.35μg/(ml·min),Cmax=2.427μg/ml,Tpeak=128.86 min;F(%)=241.77。结论川芎微乳制剂生物利用度高、达峰时间短。
Objective To compare the difference in bioavailability of ligusticum wallichii microemulsion and decoction by detecting the concentration of Ferulic acid in rabbit plasma. Methods RP-HPLC was used to detect the concentration of Ferulic acid in rabbits plasma at different times, and software 3p87 was used to analyze the pharmacokinetics parameter. Results The pharmacokinetics parameters of ligusticum wallichii microemulsion and decoction were as follows: AUC0-9=2 123.6 μg/(ml·min), Cmax=5.086 μg/ml, Tpeak=56.26 min for microemulsion;Decoction:AUC0-9=878.35 μg/(ml·min), Cmax=2.427μg/ml, Tpeak=128.86 min for decoction, F(%)=241.77. Conclusion Microemulsion of ligusticum wallichii has a higher biological availability and shorter peak time than decoction.
