大川芎方化学成分的超高效液相色谱-电喷雾-四极杆飞行时间质谱分析
摘要
目的:采用液质联用技术(LC-MS)对中药大川芎方中的化学成分进行定性分析。方法:运用ACQUITY UPLCBEH C18(2.1 mm×100 mm
Objective:To analyze and identify the chemical composition of Dachunxiong Fang by LC-MS.Method:The analysis was performed on an AQCUITY UPLC BEH C
18
(2.1 mm×100 mm
1.7 μm) column.The mobile phases were acetonitrile and water in gradient elution.ESI source was used and data were acquited in positive and negative mode.Result:The structures of 17 compounds of Dachunxiong Fang were identified by direct comparison with MS and MS
2
of Q-TOF
the elemental compositions analysis
the standard substance and the data of the literature.Furthermore
the types of the compounds were phenols
organic acids
phthalides and compounds containg nitrogen.Addition
the mass spectrum characterization of the major chemical composition of Dachunxiong Fang are analyzed.Conclusion:It is a rapid and accurate method that the composition of compound prescription of traditional Chinese medicine can be identified in terms of the separation of ultra high performance liquid chromatography
the accurate molecular weights measured by MS and other information
which can trace to the source of compounds in Dachuanxiong Fang.
