摘　　要：目的明确常通口服液(CTOL)中的化学成分,为其药效物质基础研究及二次开发提供参考。方法采用超高效液相色谱-静电场轨道阱高分辨质谱(UHPLC-Orbitrap HRMS)技术进行分析。将CTOL检测样品上样Hypersil Gold色谱柱,以0.1%甲酸(含5 mmol/L甲酸铵)-乙腈作为流动相进行梯度洗脱;采用电喷雾离子源,在正、负离子模式下进行检测,数据使用Xcalibur qual browser 4.3和Compound Discoverer 3.3软件进行处理。收集各化合物的一级、二级质谱数据,根据仪器自带的质谱库以及网络数据库mzCloud、mzVault等对未知化合物进行鉴定,并通过同中药系统药理学数据库与分析平台进行匹配,从而对各化学成分进行药材归属。结果从CTOL中共鉴定分析出53个化学成分,包括24个黄酮类化合物、8个醌类化合物、5个苯丙素类化合物、4个糖和苷类化合物、5个有机酸类化合物、3个氨基酸类化合物、1个生物碱类化合物、1个酚类化合物和2个其他类化合物。53个化合物中有12个来源于丹参,9个来源于枳实,7个来源于大黄,4个来源于当归,1个来源于厚朴,16个来源于甘草,4个来源于多味药材。结论CTOL中主要含黄酮类、醌类、苯丙素类、糖和苷类化合物,且化学成分主要来源于甘草、丹参和枳实。OBJECTIVE To identify the chemical components of Changtong oral liquid(CTOL),and to provide reference for the basic research and secondary development of its pharmacological substances.METHODS UHPLC-Orbitrap HRMS technique was adopted.CTOL sample was separated on a Hypersil Gold column with mobile phase consisted of 0.1%formic acid(containing 5 mmol/L ammonium formate)-acetonitrile(gradient elution).The eluent was detected in positive and negative ion modes using an electrospray ionization source.The data was processed by Xcalibur 4.3 and Compound Discoverer 3.3 software.The primary and secondary mass spectra data of each compound were collected.The unknown compounds were identified according to the mass spectrometry library of the instrument and the network databases mzCloud,mzVault,etc.Through matching with the pharmacology database and analysis platform of the traditional Chinese medicine system,the chemical components could be attributed to the traditional Chinese medicine.RESULTS Fifty-three chemical components were identified and analyzed from CTOL,such as 24 flavonoids,8 quinones,5 phenylpropanoids,4 sugars and glycosides,5 organic acids,3 amino acids,1 alkaloid,1 phenolic and 2 other compounds.Among them,12 components were derived from Salvia miltiorrhiza,9 from Citrus aurantium,7 from Rheum palmatum,4 from Angelica sinensis,1 from Magnolia officinalis,16 from Glycyrrhiza uralensis,and 4 from many kinds of medicinal materials.CONCLUSIONS CTOL mainly contains flavonoids,quinones and phenylpropanoid compounds,and its chemical components mainly come from G.uralensis,S.miltiorrhiza and C.aurantium.
