摘要
该研究采用高效液相色谱法建立并分析了不同厂家生产醒脑静注射液的特征图谱。采用Thermo BDS Hypersil C18色谱柱(4.6 mm×250 mm,5μm)进行分离,流动相为乙腈-0.02%甲酸水溶液,梯度洗脱,流速1.0 m L·min^(-1),检测波长254nm,柱温35℃,进样量20μL。通过对29批醒脑静注射液的HPLC特征图谱研究,共标定了11个特征峰。经与对照品对比,指认出其中7个特征峰的结构,分别为优香芹酮、樟脑、姜黄烯酮、莪术烯醇、莪术二酮、莪术酮和吉马酮。运用计算机辅助相似性评价系统及主成分分析对所建29批醒脑静注射液的HPLC特征图谱进行分析比较,结果显示不同厂家生产的醒脑静注射液能明显分为3类。该文所建立的HPLC特征图谱为科学评价和有效控制醒脑静注射液质量提供了依据。
To establish and analyze the HPLC specific chromatograms of Xingnaojing injection manufactured by different factories.The separation was performed on a Thermo BDS Hypersil C_（18）column（ 4. 6 mm × 250 mm,5 μm）,with the mobile phase consisting of acetonitrile-0. 02% formic acid aqueous solution for gradient elution. The flow rate was 1. 0 m L·min-（-1）,and the column temperature was 35 ℃. The detection wavelength was set at 254 nm,and the sample size was 20 μL. Eleven chromatographic peaks were identified as characteristic peaks of HPLC specific chromatograms of Xingnaojing injection,after analyzing 29 batches of Xingnaojing injection samples. Compared with the reference substances,seven of them were identified as eucarvone,camphor,curcumenone,curcumenol,curdione,curzerenone and germacrone,respectively. HPLC specific chromatograms of Xingnaojing injection manufactured by three factories could be easily classified into three categories after investigation with computer-aided similarity evaluation system combined with principal component analysis. The established HPLC specific chromatograms provide a basis for scientific evaluation and effective con-trol of the quality of Xingnaojing injection.
