中文摘要:

      目的 建立一测多评(quantitative analysis of multi-components by single marker, QAMS)法同时测定穿心莲中9种成分含量的分析方法。方法 采用超高效液相色谱-串联质谱法, 以穿心莲内酯为内参物, 建立该成分与连翘苷、齐墩果酸、咖啡酸、穿心莲内酯、脱水穿心莲内酯、穿心莲新酯、去氧穿心莲内酯、脱水穿心莲内酯琥珀酸半酯、亚硫酸氢钠穿心莲内脂的相对校正因子, 利用相对校正因子来计算各成分的含量, 同时将QAMS法计算结果和外标法实测值进行比较。结果 相对校正因子重现性良好, 使用QAMS法与外标法所测得的结果无明显的差异。结论 QAMS法适用于穿心莲中9种成分的同时测定, 以保证质量的可靠性。

英文摘要:

      Objective To establish a quantitative analysis of multi-components by single marker (QAMS) method for the simultaneous determination of 9 kinds of components in Andrographis paniculata. Method The relative calibration factors of andrographolide with forsythitin, oleanolic acid, caffeic acid, andrographolide, dehydrated andrographolide, andrographolide, deoxyandrographolide, dehydrated andrographolide half succinate and sodium bisulfite were established by ultra performance liquid chromatographolide-tandem mass spectrometry. The relative correction factor was used to calculate the content of each component, and the calculated results of QAMS method were compared with the measured values of external standard method. Results The relative correction factors showed good reproducibility, and there was no significant difference between the results obtained by the QAMS method and the external standard method. Conclusion The QAMS method is suitable for the simultaneous determination of 9 kinds of components in Andrographis paniculata, ensuring the reliability of quality.
