目的研究谷红注射液中羟基红花黄色素A在大鼠体内的药代动力学特征,比较单体状态与注射液中羟基红花黄色素A药代动力学差异。方法 HPLC法测定经尾静脉注射给药后大鼠血浆中羟基红花黄色素A的浓度,运用PKSolver 2.0软件拟合药时曲线,对药代动力学参数进行分析。结果羟基红花黄色素A单体与谷红注射液中羟基红花黄色素A的主要药代动力学参数α、β、t1/2α、t1/2β、C0、V、CL、AUC0-150、AUC0-inf分别为(0.306 9±0.136 4)和(0.091 8±0.079 3)/min,(0.016 4±0.003 1)和(0.010 5±0.003 0)/min,(2.738 6±1.163 4)和(22.020 0±19.970 3)min,(43.819 9±8.607 7)和(74.941 1±32.794 3)min,(21.309 8±2.957 3)和(26.579 9±3.763 5)μg/m L,(0.098 1±0.013 5)和(0.078 6±0.010 7)L/kg,(0.003 4±0.000 5)和(0.001 2±0.000 2)(L/kg)/min,(567.774 4±66.149 7)和(1 391.658 0±159.754 7)(min·μg)/m L,(625.723 0±96.292 6)和(1 734.929 2±222.467)(min·μg)/m L。结论与羟基红花黄色素A单体比较,谷红注射液中羟基红花黄色素A在大鼠体内的AUC明显增大。
AIM To study the pharmacokinetics characters of hydroxysafflor yellow A( HSYA) in Guhong Injection in rats and compare its pharmacokinetics difference with HSYA monomer. METHODS After intravenous injection,the concentration of HSYA in rat plasma was determined by HPLC. The concentration-time curve was fitted with PKSolver 2. 0 software to analyze the pharmacokinetics parameters. RESULTS The main pharmacokinetics parameters of α,β,t1 /2 α,t1 /2 β,C0,V,CL,AUC0- 150,AUC0- infwere( 0. 306 9 ± 0. 136 4) and( 0. 091 8 ±0. 079 3) / min,( 0. 016 4 ± 0. 003 1) and( 0. 010 5 ± 0. 003 0) / min,( 2. 738 6 ± 1. 163 4) and( 22. 020 0 ±19. 970 3) min,( 43. 819 9 ± 8. 607 7) and( 74. 941 1 ± 32. 794 3) min,( 21. 309 8 ± 2. 957 3) and( 26. 579 9± 3. 763 5) μg / m L,( 0. 098 1 ± 0. 013 5) and( 0. 078 6 ± 0. 010 7) L / kg,( 0. 003 4 ± 0. 000 5) and( 0. 001 2± 0. 000 2)( L / kg) / min,( 567. 774 4 ± 66. 149 7) and( 1 391. 658 0 ± 159. 754 7)( min · μg) / m L,( 625. 723 0 ± 96. 292 6) and( 1 734. 929 2 ± 222. 467)( min·μg) /m L,respectively. CONCLUSION Compared with HSYA monomer,the AUC of HSYA in Guhong Injection in rats increases significantly.
