TITLE: Identification of chemical constituents of modified Yupingfengsan formula
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WatersBEHC18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/z50~1500,喷雾电压为2kV(正离子模式)、1.5kV(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。
ABSTRACT: OBJECTIVE To identify the chemical constituents of the modified Yupingfengsan formula. METHODS UPLC-Q- Exactive 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 50-1 500, and the spray voltage was 2 kV (positive ion mode) and 1.5 kV (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, 5 saponins, 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-O- glucosylhamaudol, luteolin and mangiferin. These constituents mainly involved glycosylation cleavage, retro Diels-Alder fragmentation, glycosylation loss, neutral molecule loss and other fragmentation pathways.
