摘要
目的:建立同时测定Raw264.7细胞中羊耳菊提取物中7个抗炎活性成分木犀草苷(luteolin,LUT)、绿原酸(chlorogenic acid,CA)、新绿原酸(neochlorogenic acid,NCA)、隐绿原酸(cryptochlorogenic acid,CCA)、3,4-二咖啡酰基奎宁酸(3,4-dicaffeoylquinic acid,3,4-DCQA)、3,5-二咖啡酰基奎宁酸(3,5-dicaffeoylquinic acid,3,5-DCQA)、4,5-二咖啡酰基奎宁酸(4,5-dicaffeoylquinic acid,4,5-DCQA)含量的方法。方法:以小鼠巨噬细胞Raw 264.7为研究对象,采用超高液相色谱-三重四级杆质谱联用仪(UPLC-MS/MS)建立同时测定Raw 264.7细胞中LUT、CA、NCA、CCA、3,4-DCQA、3,5-DCQA、4,5-DCQA等7个成分含量的方法,包括专属性、线性、基质效应、回收率、准确度、精密度和稳定性等。结果:建立了一个快速稳定测量Raw264.7细胞中微量药物的分析方法,该方法的最低定量限为0.48~3.84 ng/mL,准确度为(90.78±5.30)%~(113.99±13.51)%,提取回收率为(87.19±5.33)%~(103.59±14.00)%,基质效应为(94.50±15.17)%~(112.77±7.02)%,稳定性为(91.71±11.70)%~(109.45±10.63)%,能够满足测量的要求。结论:建立了快速、准确的同时测定Raw264.7细胞羊耳菊提取物中7个活性成分(LUT、CA、NCA、CCA、3,4-DCQA、3,5-DCQA、4,5-DCQA)含量的UPLC-MS/MS方法,为开展羊耳菊提取物的细胞药代动力学研究奠定基础。
Objective:To establish a method simultaneously determining the contents of seven anti-inflammatory active components including luteolin(LUT),chlorogenic acid(CA),and neochlorogenic acid(NCA),cryptochlorogenic acid(CCA),3,4-dicaffeoylquinic acid(3,4-DCQA),3,5-dicaffeoylquinic acid(3,5-DCQA),4,5-dicaffeoylquinic acid(4,5-DCQA)of the Miao medicine Inula cappa in Raw264.7 cells.Methods:Using mouse macrophage Raw264.7 as the research object,ultra-high liquid chromatography-triple quadrupole mass spectrometry(UPLC-MS/MS)was used to establish the simultaneous determination of LUT,CA,NCA,CCA,3,4-DCQA,3,5-DCQA,4,5-DCQA methods for the content of seven components of the Miao medicine Inula cappa,including specificity,linearity,matrix effect,recovery,accuracy,precision and stability.Results:A rapid and stable analytical method for the measurement of trace drugs in Raw264.7 cells was established.The lowest limit of quantification of the method was 0.48-3.84 ng/mL,and the accuracy was(90.78±5.30)%-(113.99±13.51)%.Its extraction recovery was(87.19±5.33)%-(103.59±14.00)%and the matrix effect was(94.50±15.17)%-(112.77±7.02)%.The stability was(91.71±11.70)%-(109.45±10.63)%,which could meet the measurement requirements.Conclusion:A rapid and accurate method for simultaneous determination content of seven active components LUT,CA,NCA,CCA,3,4-DCQA,3,5-DCQA,4,5-DCQA using UPLC-MS/MS was established,which could provide a reference for the study of cellular pharmacokinetics of Inula cappa extract.
