摘要: [摘要]目的:采用液相色谱-质谱串联(LC原MS/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 3,29原二苯甲酰基栝楼仁三醇(3,29原DK)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:SPF 级 SD 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 0.5、1、2、3、4、6、8、10、12、24、36、48 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 5、10、30 min,1、1.5、2、3、4、6、8 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 3,29原DK 达峰时间、AUC 和 t 1/2 显著延长(P<0.05),MRT 显著增加(P<0.05),CLz/F、C max 明显降低(P<0.05)。结论:瓜蒌薤白微丸中 3,29原DK 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: 〔Abstract〕Objective:To study the plasma concentration and pharmacokinetics of 3,29-dibenzoyl-karounitriol (3,29-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 spectrometry (LC-MS/MS). Methods:12 SPF SD male rats were randomly divided into
Gualou- Xiebai pellets group(2.0 g/kg)and Gualou-Xiebai extracts group(1.4 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 5,10,30 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 3,29-DK peak time,AUC and t 1/2 in the Gualou-Xiebai pellet group were significantly prolonged(P<0.05),and MRT was significantly increased(P<0.05),CLz/F,C max was significantly reduced(P<0.05). Conclusion: The release rate of 3,29-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.
