UPLC-QTOF/MS法分析乳宁颗粒化学成分及入血成分

Analyses of chemical constituents and constituents absorbed into blood from Runing Granules by UPLC⁃QTOF/MS

目的建立UPLC-QTOF/MS法分析乳宁颗粒化学成分及入血成分。方法2只大鼠灌胃给予颗粒水溶液,于0、0.5、1、2、4h采血。分析采用AcquityUPLCBEHC_(18)色谱柱(100mm×2.1mm,1.7μm);流动相0.1%甲酸-乙腈(正离子)或水-乙腈(负离子),梯度洗脱;体积流量0.3mL/min;柱温40℃;电喷雾离子源;正负离子扫描。结果共鉴定出166种化学成分,包括44种黄酮类、17种萜类、23种生物碱类、11种皂苷类、29种酚酸类、13种醌类、10种有机酸类、19种其他类,以及11种入血成分。结论该方法准确稳定,可为乳宁颗粒临床应用提供数据支撑,也能为其后续质量控制、物质基础研究奠定基础。

AIM To establish a UPLC⁃QTOF/MS method for the analyses of chemical constituents and constituents absorbed into blood from Runing Granules.METHODS Two rats were given intragastric administration of the aqueous solution of granules,after which blood collection was made at 0,0.5,1,2,4 h.The analysis was performed on a 40℃thermostatic Acquity UPLC BEH C_(18) column(100 mm×2.1 mm,1.7μm),with the mobile phases comprising of 0.1%formic aciD⁃acetonitrile(positive ion)or water⁃acetonitrile(negativeion)flowing at 0.3 mL/min in a gradient elution manner,and electron spray ionization source was adopted in positive and negative ion scanning.RESULTS Total 166 chemical constituents were identified,containing 44 flavonoids,17 terpenes,23 alkaloids,11 saponins,29 phenolic acids,13 quinones,10 organic acids,and 19 others,along with 11 constituents absorbed into blood.CONCLUSION This accurate and stable method can provide a data support for the clinical application of Runing Granules,and lay foundations for the further researches on their quality control and material basis.
