摘要: 目的:研究脉络宁注射液中酚酸类成分在大鼠体内药代动力学规律。方法:大鼠尾静脉注射给予脉络宁注射液10mL/kg,给药前及给药后不同时间采集血样或尿样,LC-MS法测定酚酸类成分浓度,血药浓度-时间数据和尿药排泄量-时间数据用DAS软件进行动力学分析。结果:绿原酸(CGA)、1,5-二咖啡酰奎宁酸(1,5-DCQA)、3,4-二咖啡酰奎宁酸(3,4-DCQA)、3,5-二咖啡酰奎宁酸(3,5-DCQA)和咖啡酸(CA)血药浓度迅速下降达峰,消除t1/2分别为0.649、0.334、0.479、0.486、0.330h,AUC0-∞分别是(22.522±2.716)(CGA)、(0.353±0.062)(1,5-DCQA)、(3.620±1.246)(3,4-DCQA)、(5.287±1.627)(3,5-DCQA)和(2.257±0.360)(CA)mg·L-1·h。CGA、1,5-DCQA、3,4-DCQA、3,5-DCQA和CA在尿中0~24h累积排泄率分别为(122.22±26.49)%、(3.30±1.26)%、(0.24±0.11)%、(1.93±0.77)%和(18.61±4.99)%,尿排泄t1/2在1~4h。结论:脉络宁注射液中酚酸类成分在体内迅速被排泄出体外,CGA、1,5-DCQA、3,4-DCQA、3,5-DCQA和CA均可从尿排泄,但其中1,5-DCQA、3,4-DCQA、3,5-DCQA和CA尿药排泄量较少,存在其他代谢途径。

Abstract: AIM: To study the pharmacokinetics of phenolic acids from Mailuoning injection in rats. METHODS: SD rats were given a single i.v.administration dose of Mailuoning injection 10 mL/kg, plasma and urine were collected before and after injection. Phenolic acid components in plasma and urine were measured by LC MS.Pharmacokinetic parameters were determined from the plasma concentration-time data and urinary excretion-time data with the DAS software package.RESULTS: After i.v.of Mailuoning injection, chlorogenic acid (CGA), 1, 5-dicaffeylquinic acid (1, 5-DCQA), 3, 4-dicaffeylquinic acid (3, 4-DCQA), 3, 5-dicaffeylquinic acid (3, 5-DCQA)and caffeic acid (CA)were quickly excrectioned.The t1/2 of CGA, 1, 5-DCQA, 3, 4-DCQA, 3, 5-DCQA and CA were 0.649, 0.334, 0.479, 0.486 and 0.330 h, respectively.AUC0-∞ were (22.522±2.716), (0.353±0.062), (3.620±1.246), (5.287±1.627)and (2.257±0.360)mg·L-1 ·h, respectively.After i.v. of Mailuoning injection, CGA, 1, 5-DCQA, 3, 4-DCQA, 3, 5-DCQA and CA can all be detected in the urine.The amounts of CGA, 1, 5-DCQA, 3, 4-DCQA, 3, 5-DCQA and CA excreted from urine during 0-24 h were (122.22±26.49)%, (3.30±1.26)%, (0.24±0.11)%, (1.93± 0.77)% and (18.61± 4.99)% of dose given in rats, respectively.CONCLUSION: After i.v.of Mailuoning injection, phenolic acids can be excreted quickly.Only a small quantity of 1, 5-DCQA, 3, 4-DCQA, 3, 5-DCQA and CA were excreted from urine.3, 4-DCQA and 3, 5-DCQA may be metabolized into CGA in the rat plasma.
