摘要
目的使用超高效液相色谱-四级杆飞行时间串联质谱(UHPLC-Q-TOF-MS/MS)方法鉴定白背叶叶提取物中的化学成分。方法通过UHPLC-Q-TOF-MS/MS获取其裂解信息,结合二级质谱数据库、Scifinder数据库等,结合Progenesis SDF Studio软件、Progenesis QI软件和搜索文献进行MS和MS/MS碎片解析。结果鉴定出63个化学成分,包括21个有机酸类、19个黄酮类、6个酚类、4个酯类、4个醇类、3个生物碱类、2个糖类、2个醛类、1个胆碱类及1个喹啉类,所鉴定出成分的准确质量测量结果均为±5 ppm误差。结论通过该方法对白背叶叶提取物中的化学成分进行全面的分析,为白背叶药材化学成分分析提供基础。
Objective To identify the chemical constituents of the leaves of Mallotus apelta using ultra high performance liquid chromatography coupled with quadruple time of flight mass spectrometry(UHPLC-Q-TOF-MS/MS).Methods The fragmentation information was obtained by UHPLC-Q-TOF-MS/MS,combined with secondary mass spectrometry database,Scifinder database,etc.Combined with Progenesis SDF Studio software,Progenesis QI software and literature search,MS and MS/MS fragment analysis were carried out.Results A total of 63 chemical components were identified,including 21 organic acids,19 flavonoids,6 phenols,4 esters,4 alcohols,3 alkaloids,2 sugars,2 aldehydes,1 choline,and 1 quinoline,and the accurate mass measurement results of the identified components are all±5 ppm error.Conclusion This method provides a comprehensive analysis of the chemical constituents of the leaves of Mallotus apelta,which provides a basis of the analysis for the chemical constituents of medicinal materials of the Mallotus apelta.
