| 目的 建立大鼠体内的没食子酸和原儿茶酸的反相高效液相色谱分析方法,研究檀香对广枣中没食子酸、原儿茶酸在大鼠体内药代动力学的影响。方法 给SD大鼠灌服广枣水提液和广枣-檀香水提液,采用反相高效液相色谱法测定大鼠给药后不同时间血浆中原儿茶酸和没食子酸的浓度,DAS2.0药动学软件拟合房室模型,计算药动学参数。结果 广枣水提液组没食子酸的主要药动学参数Cmax为 (0.112±0.008) mg·L-1,CL/F (0.132±0.016) L·min-1·kg-1;Tmax (45.0±0) min,t1/2β (69.3±0) min;原儿茶酸的主要药动学参数Cmax为 (0.550±0.028) mg·L-1, Tmax (52.0±0) min,CL/F (0.078±0.011) L·min-1·kg-1,t1/2β (60.7±1.1) min。广枣-檀香水提液组没食子酸的主要药动学参数Cmax为 (0.187±0.010) mg·L-1,CL/F (0.094±0.017) L·min-1·kg-1,Tmax (30.0±0) min,t1/2β (69.3±3.3) min;原儿茶酸的主要药动学参数Cmax为(1.080±0.066) mg·L-1,Tmax (45.0±0) min,T1/2β (69.3±0.2) min,CL/F (0.011±0.001) L·min-1·kg-1。 结论 广枣-檀香水提液组没食子酸和原儿茶酸的达峰时间提前,清除率降低,半衰期延长,提示檀香可促进广枣中酚酸类物质吸收,延缓其消除。 |

| Abstract: |
| Objective To establish a HPLC method for in vivo determination of gallic acid (GA) and protocatechuic acid (PA) in rat plasma, and to study the effect of Sandalwood on the pharmacokinetics of GA and PA. Methods SD rats were given the water extracts of Choerospondiatis fruit or Choerospondiatis fruit and Sandalwood. The pharmacokinetic parameters of GA and PA were calculated by DAS2.0 software at different time points after an oral ration of the above extracts. Results The pharmacokinetic parameters after oral administration of Choerospondiatis fruit extract were as follows:GA: Cmax:(0.112±0.008) mg·L-1, CL/F: (0.132±0.016) L·min-1·kg-1, t1/2β: (69.3±0) min, Tmax: (45.0±0) min; PA: Cmax: (0.550±0.028) mg·L-1, Tmax: (52.0±0) min, t1/2β: (60.7±1.1) min; CL/F: (0.078±0.011) L·min-1·kg-1. The pharmacokinetic parameters after oral ration of Choerospondiatis fruit-Sandalwood extract were as follows: GA: Cmax: (0.187±0.010) mg·L-1, CL/F: (0.094±0.017) L·min-1·kg-1, t1/2β:(69.3±3.3) min, Tmax: (30.0±0) min; PA: Cmax: (1.080±0.066) mg·L-1, Tmax: (45.0±0) min, t1/2β: (69.3±0.2) min, CL/F:(0.011±0.001) L·min-1·kg-1. Conclusion Oral ration of Choerospondiatis fruit-Sandalwood extract results in earlier plasma peaks of PA and GA, lower clearance rate, and longer half life, indicating Sandalwood can promote the absorption of phenolic compounds in Choerospondiatis fruit. |
