延胡索抗心肌缺血活性部位指纹图谱中化学成分分析

目的:运用LC-MS²技术对延胡索抗心肌缺血活性部位指纹图谱中化学成分进行分析,初步了解其主要活性成分.方法:采用迪马公司Diamonsil C₁₈柱(4.6 mm×250 mm,5 μm),流动相为乙腈-水(含0.8%冰醋酸和0.2%三乙胺23:77),流速1 mL·min^-1,检测波长335 nm,柱温30℃.结果:建立了延胡索抗心肌缺血活性部位的HPLC指纹图谱,确立了指纹图谱中的12个共有峰,根据所检测到化合物的色谱保留时间及多级质谱信息,与对照品比较,对其中8个色谱峰进行了指认.结论:本方法为延胡索抗心肌缺血活性部位的质量控制提供了依据.

Analysis of chemical constituents of anti-myocardial ischemia fraction of Corydalis yanhusuo

OBJECTIVE: To establish the HPLC fingerprint of anti-myocardial ischemia fraction of Corydalis yanhusuo, and to investigate its chemical constituents by LC-MS-MS. METHOD: The separation was performed at 30 degrees C on a Dikma Diamonsil C18 column (4.6 mm x 250 mm, 5 microm) by isocratic elution with acetonitrile-water (23:77) (containing 0.8% acetic acid and 0.2% triethylamine) as the mobile phase at a flow rate of 1.0 mL x min(-1), with UV detection at 335 nm. RESULT: A satisfactory fingerprint was obtained by HPLC method, 12 common peaks were selected as the fingerprint peaks, and 8 among them were identified according to the chromatographic behavior and mass spectroscopic data by comparison with those of authentic standard. CONCLUSION: This method is simple, sensitive and reliable, can be used to investigate the chemical constituents of anti-myocardial ischemia fraction of C. yanhusuo and control the quality.
