四神丸方的化学成分及入血成分分析

Identification of Chemical Components and Components Absorbed into Blood of Sishen Pills

目的采用超高效液相色谱-四极杆-静电场轨道阱高分辨质谱技术对四神丸方的化学成分及入血成分进行初步鉴定和分类归属。方法将SD大鼠分为空白组和给药组,给药组大鼠灌胃给予四神丸方水提液,分别采集空白及含药血浆。采用Hypersil GOLD VANQUISH色谱柱(2.1 mm×100 mm,1.9μm),以0.1%甲酸水-乙腈为流动相,梯度洗脱,体积流量0.3 mL·min^(-1),柱温35℃;采用电喷雾离子源(ESI),正、负离子扫描模式,进行色谱分离和质谱数据采集。将精确相对分子质量、碎片离子信息和相对保留时间与对照品图谱比对、与自建数据库匹配并结合文献报道,鉴定四神丸方化学成分;在此基础上比对空白血浆和含药血浆,分析四神丸方入血成分。结果从四神丸方中共鉴定出181种化学成分,主要包括黄酮类、生物碱类、木脂素类等成分。从血浆样本中共鉴定出49种原型入血成分,主要包括黄酮类、生物碱类等成分。结论全面、准确、快速地识别鉴定了四神丸方及其含药血浆中多种化学成分,各类成分归属到了方中各味药材,为四神丸方质量控制、药效物质基础研究及临床应用提供参考。

OBJECTIVE To identify and classify the chemical components and components absorbed into blood of Sishen Pills using ultra-high performance liquid chromatography-quadrupole-orbitrap high resolution mass spectrometry.METHODS SD rats were divided into blank group and drug administration group.The rats in drug administration group were given water extract of Sishen Pills formula intragastrically,and blank and drug-containing plasma were collected respectively.A Hypersil GOLD VANQUISH column(2.1 mm×100 mm,1.9μm)was used,with 0.1%formic acid water acetonitrile as the mobile phase,gradient elution,volume flow rate of 0.3 mL·min^(-1),and column temperature of 35℃.Electrospray ion source(ESI)with positive and negative ion scanning mode was used for chromatographic separation and mass spectrometry data acquisition.The chemical components of Sishen Pills were identified by comparing the exact molecular mass,fragment ion information and relative retention time with the map of reference substance,matching with the self-established database and combining with literature reports.On this basis,the components absorbed into blood of Sishen Pills were analyzed by comparing the blank plasma and drug-containing plasma.RESULTS A total of 181 chemical components were identified from Sishen Pills,mainly including flavonoids,alkaloids,lignans and other components.A total of 49 prototype blood components were identified from the plasma samples,mainly including flavonoids,alkaloids and other components.CONCLUSION A variety of chemical components in Sishen Pills and drug-containing plasma are comprehensively,accurately and quickly identified,and all of them are assigned to the various medicinal materials in the prescription.This study provides reference for the quality control,basic research on medicinal effect materials and clinical application of Sishen Pills.
