摘要: 目的:采用液相色谱-质谱串联(LCMS/MS)法考察瓜蒌薤白胃内漂浮微丸(以下简称“瓜蒌薤白微丸”)中329-二苯甲酰基栝楼仁三醇(329DK)在大鼠体内不同时间点的血药浓度及药代动力学特征。方法:SPFSD雄性大鼠12只,随机分为瓜蒌薤白微丸组(2.0 g/kg)和瓜蒌薤白提取物组(1.4 g/kg)。瓜蒌薤白微丸组于大鼠灌胃给药前0 h及给药后第0.51234681012243648 h眼内眦取血,瓜蒌薤白提取物组于给药前0 h及给药后第51030 min11.523468 h眼内眦取血,计算药代动力学参数。结果:与瓜蒌薤白提取物组相比,瓜蒌薤白微丸组中329DK达峰时间、AUCt1/2显著延长(P<0.05),MRT显著增加(P<0.05),CLz/FCmax明显降低(P<0.05)。结论:瓜蒌薤白微丸中329DK在大鼠体内释放速率较为平稳,无突释、速释现象,代谢时间延长。瓜蒌薤白微丸具有缓释作用。

Abstract:

 Objective To study the plasma concentration and pharmacokinetics of 329-dibenzoyl-karounitriol 329-DK in Gualou-Xiebai intragastric floating pellets hereinafter referred to as "Gualou-Xiebai pellets" at different time points in rats by liquid chromatography tandem mass spectrometryLC-MS/MS. Methods 12 SPF SD male rats were randomly divided into Gualou- Xiebai pellets group2.0 g/kg and Gualou-Xiebai extracts group1.4 g/ kg), the blood samples were taken from the orbit 0 h before administration and 0.5 1 2 3 4 6 8 10 12 24 36 48 h after administration in Gualou-Xiebai pellets group the blood samples were taken from the orbit 0 h before administration and 51030 min 1 1.5 2 3 4 6 and 8 h after administration in the Gualou-Xiebai extracts group and the pharmacokinetic parameters were calculated. Results Compared with the Gualou-Xiebai extracts group the 329-DK peak time AUC and t1/2 in the Gualou-Xiebai pellet group were significantly prolonged P<0.05), and MRT was significantly increased P<0.05), CLz/F Cmax was significantly reduced P<0.05. Conclusion The release rate of 329-DK in Gualou-Xiebai pellets was stable in rats without sudden release and rapid release and the metabolic time was prolonged. Gualou-Xiebai pellets have sustained-release effect.
