| 摘要: |
| 目的 运用鸡尾酒法评价石蒜对细胞色素P450酶活性的影响。方法 将大鼠随机分为对照组和石蒜低、高剂量组。对照组给予生理盐水，石蒜低、高剂量组大鼠灌胃给药0.5，1.0 g·kg-1石蒜，连续给药15 d。然后第16天给予探针药物，UPLC-MS/MS检测探针药浓度。结果 与对照组对比，石蒜低剂量组和高剂量组的安非他酮AUC（0-t）、Cmax都显著升高（P<0.05），CLz/F显著降低（P<0.05）。与对照组对比，石蒜高剂量组的美托洛尔、咪达唑仑和非那西丁AUC（0-t）显著降低（P<0.05）、CLz/F显著升高（P<0.05），而低剂量组与对照组比较差异无统计学意义。与对照组对比，石蒜组的甲苯磺丁脲AUC（0-t）、CLz/F差异无统计学意义，Cmax显著降低（P<0.05）。结论 石蒜能抑制大鼠CYP2B1酶活性，诱导大鼠CYP2D1、CYP3A2和CYP1A2酶活性，稍有诱导大鼠CYP2C11酶活性的作用。 |

| Abstract: |
| OBJECTIVE To evaluate the effect of Lycoris radiata on cytochrome P450 enzyme activity using the cocktail method. METHODS Rats were randomly divided into three groups:the control group, low and high dose of Lycoris radiata group. The control group was given physiological saline, and the rats in the low and high dose of Lycoris radiata group were intragastrically administrated 0.5, 1.0 g·kg-1 of Lycoris radiata for 15 d. Then on the 16th day, probe drugs were administrated by gavage, and the concentration of probe drugs was determined by UPLC-MS/MS. RESULTS Compared with the control group, the AUC(0-t) and Cmax of bupropion in the low and high dose of Lycoris radiata group increased(P<0.05) and the CLz/F decreased(P<0.05). Compared with the control group, the AUC(0-t) of metoprolol, midazolam, and phenacetin in the high dose Lycoris radiata group decreased(P<0.05), and CLz/F increased(P<0.05), while there was no statistical difference between the low dose Lycoris radiata group and the control group. Compared with the control group, the AUC(0-t)and CLz/F of tolbutamide in the Lycoris radiata group were not statistically different, but the Cmax of the Lycoris radiata group decreased(P<0.05). CONCLUSION Lycoris radiata can inhibit CYP2B1 enzyme activity in rats, induce CYP2D1, CYP3A2 and CYP1A2 enzyme activities in rats, and slightly induce CYP2C11 enzyme activity in rats. |
