摘要
目的鉴定玉屏风散加味方的化学成分。方法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。以Waters BEH C18为色谱柱,乙腈(A)-0.1%甲酸溶液(B)为流动相进行梯度洗脱;采用加热电喷雾离子源进行正、负离子模式扫描,扫描范围为m/z 50~1500,喷雾电压为2 kV(正离子模式)、1.5 kV(负离子模式)。通过查阅文献收集玉屏风散加味方的化学成分信息,建立数据库;结合上述成分数据库、相关文献以及对照品的色谱、质谱信息对该方成分结构进行鉴定。结果与结论从玉屏风散加味方中共鉴定出114个化学成分,包括黄酮类(31个)、苯丙素类(39个)、皂苷类(5个)、萜类(8个)、色原酮类(3个)、姜辣素类(3个)等;通过与对照品比对,最终确定了8个成分,分别为木兰花碱、毛蕊异黄酮、毛蕊异黄酮葡萄糖苷、升麻素、5-O-甲基维斯阿米醇苷、亥茅酚苷、木犀草素、芒柄花素;主要涉及糖基断裂、逆狄尔斯-阿尔德重排、糖基丢失、中性分子丢失等裂解途径。
OBJECTIVE To identify the chemical constituents of the modified Yupingfengsan formula.METHODS UPLC-QExactive Orbitrap-MS technology was adopted.The separation was performed on Waters BEH C18 column with acetonitrile(A)-0.1%formic acid solution(B)as mobile phase for gradient elution.The heating electrospray ionization was used for positive and negative ion mode scanning.The scanning range was m/z 50-1500,and the spray voltage was 2 kV(positive ion mode)and 1.5 k V(negative ion mode).The information of chemical constituents of modified Yupingfengsan formula was collected through literature review to establish a database;the structure of the constituent was identified based on the above database,relevant literature,and chromatography and mass spectrometry information of reference standards.RESULTS&CONCLUSIONS Totally 114 chemical constituents were identified from modified Yupingfengsan formula,including 31 flavonoids,39 phenylpropanoids,5saponins,8 terpenoids,3 chromones,3 curcuminoids,etc.Based on the comparison of reference standards,8 constituents were ultimately determined,including magnoflorine,calycosin,calycosin glycoside,cimifugin,5-O-methylvisammioside,sec-Oglucosylhamaudol,luteolin and mangiferin.These constituents mainly involved glycosylation cleavage,retro Diels-Alder fragmentation,glycosylation loss,neutral molecule loss and other fragmentation pathways.
