摘 要:目的制备白花前胡甲素脂质体并进一步研究其在大鼠体内的药动学。方法采用乙醇注入法制备白花前胡甲素脂质体,采用正交设计优化处方。白花前胡甲素脂质体按5、10、20mg·kg^(-1)低、中、高3个剂量经大鼠颈静脉给药后检测一定时间点的血药浓度,对照组为10mg·kg^(-1)的白花前胡甲素溶液。结果制备的脂质体含药量为2g·L^(-1),包封率为93.2%,脂质体高、中、低剂量组及对照组的t_(1/2)分别为(136.58±22.86),(74.12±6.97),(44.93±7.47),(51.26±5.13)min;AUC_(0-∞)分别为(215.93±33.24),(91.75±26.47),(29.22±4.47),(66.90±14.54)min·mg·L^(-1)。结论成功制备了白花前胡甲素脂质体,制得的白花前胡甲素脂质体在大鼠体内半衰期显著延长,生物利用度有明显的提高。AIM To study the pharmacokinetics of d/-praeruptorin A liposomes in rats by LC-MS/MS method. METHODS dl-Praeruptorin A liposomes was obtained by the ethanol injection method. Pharmacokinetic parameters were determined after intravenous administration of d/-praeruptorin A liposomes (5, 10 and 20 rag" kg-1) and d/-praeruptorin A solution (control solution, 10 mg'kg-l) in rats. RESULTS The drug content was 2 g· L-1, encapsulation efficiency was 93.2%. The t1/2 of d/-praeruptorin A liposomes (5, 10 and 20 mg·kg-1) and control solution were (136.58 ± 22.86) (74.12 ± 6.97), (44.93 ±7.47), (51.26±5.13) min, AUC0-∞ were (215.93±33.24) , (91.75 ± 26.47) , (29.22 ±4.47) , CONCLUSION dl-praeruptorin A liposomes can increase the (66.90± 14.54) min'mg.L-1, respectively bioavailability and has a long half-life in rats
