摘要
目的:确定芫花药材致肝毒性部位,为全面反映并控制其毒性部位的质量建立该部位超高效液相色谱指纹图谱。方法:通过血清生化指标和组织病理学筛选芫花致肝毒性部位;并以采用ACQUITY UPLC BEH C18色谱柱(2.1 mm×50mm,1.7μm),乙腈-0.05%磷酸溶液为流动相,梯度洗脱,210 nm为检测波长建立该部位UPLC指纹图谱。结果:确定了芫花致肝毒性部位为其乙醇提取物的氯仿萃取物;并建立了该部位的UPLC指纹图谱共有模式,标定了17个共有峰,指认了8个色谱峰,14批芫花药材致肝毒性部位的相似度为0.890～0.999。结论:芫花致肝毒性部位为其乙醇提取物的氯仿萃取物,所建立的UPLC指纹图谱,可为芫花临床安全用药提供依据。
Objective： To look for the active fraction of ethanol extract of Genkwa Flos （EGF） induced hepatotoxicity and de- velop an UPLC fingerprint of the active fraction. Method ： Target fraction of EGF induced hepatotoxicity was guided by the serum bio- chemical and histopathology methods. The UPLC method was applied to establish the chromatographic fingerprint. The separation was achieved on a BEH C18 column （2.1 mm ×50 mm, 1.7 μm） with a mobile phase consisting of acetonitrile and water containing 0.05% phosphate acid running gradient elution. The detection was carried out at 210 nm and the analysis was finished within 10 min, Result： The chloroform phase of EGF could be responsible for the hepatotoxicity of this herb. The common mode of the UPLC finger- print was set up under the established condition. There were 17 common peaks in fourteen batches of herbs, eight of which were identi- fied, and the similar degrees of the fourteen batches to the common mode were between 0. 890-0. 999. Conclusion ： It is easy to locate the chloroform extraction of EGF with hepatotoxicity. And the UPLC fingerprint was developed for the above fraction, which could pro- vide valuable references for safe and effective clinical use of EGF.
