本研究基于超高效液相色谱-四极杆-静电场轨道阱高分辨质谱法(ultra-performance liquid chromatography tandem quadrupole electrostatic field orbitrap high resolution mass spe
ctrometry
UPLC-Q-Orbitrap HRMS)分析地榆及其炮制品地榆炭化学成分,并通过化学模式识别方法分析二者的差异成分。采用Waters BEH C
18
(100 mm×2.1 mm,1.7 μm)色谱柱进行分离;以0.1%甲酸水溶液-乙腈为流动相进行梯度洗脱,采用电喷雾离子源,正、负离子模式下采集数据。根据分子离子峰精确质量数和二级碎片信息,结合文献及数据库,共鉴定出地榆、地榆炭中共41个化学成分,其中酚类17个、黄酮类12个、三萜类9个及其他类化合物3个。应用SIMCA 14.1软件对各化合物峰面积进行主成分分析和正交偏最小二乘判别分析,筛选地榆与地榆炭差异成分。炒炭后收敛止血活性成分没食子酸、地榆皂苷Ⅱ、委陵菜酸与熊果酸在炒炭后含量升高,而葡萄糖没食子鞣苷、儿茶素、短叶苏木酚酸、鞣花酸及坡模酸含量降低。结果表明地榆炭中的三萜和酚类化合物可能是其收敛止血功效增强的主要内在物质基础。本研究可为地榆炒炭炮制后止血作用增强的内在机制提供科学参考。
This study applied ultra-performance liquid chromatography tandem quadrupole electrostatic field orbitrap high resolution mass spectrometry (UPLC-Q-Orbitrap-HRMS) to analyze the changes of chemical constituents of
Sanguisorba officinalis
before and after carbonized
and to screen the different hemostatic components. Waters BEH C18(100 mm×2. 1 mm
1. 7 μm) column was used to process with acetonitrile and 0. 1% formic acid water solution as the mobile phase for gradient elution. The heated electrospray ion source (HESI) was adopted to collect the data in both positive and negative ionization modes. Based on the accurate mass
fragment ions
literature and net-work database
a total of 41 chemical components were identified by matching precise molecular ion masses
MS/MS fragmentation patterns
literature data
and database references. These included 17 phenolic acids
12 flavonoids
9 triterpenoids
and 3 other compounds. Principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) were conducted using SIMCA 14.1 software to screen differential components between
Sanguisorba officinalis
before and after carbonization. After carbonization
the contents of hemostasis-enhancing components (gallic acid
ziyuglycoside Ⅱ
tormentic acid and ursolic acid) increased significantly
while glucogallin
catechin
brevifolin carboxylic acid
ellagic acid and pomolic acid decreased. The results showed that triterpenoids and phenolic compound
s in
Sanguisorba officinalis
after carbonized may constitute the key material basis for its enhanced astringent hemostatic effect. This investigation provides scientific insights into the intrinsic mechanisms underlying the strengthened hemostatic efficacy of
Sanguisorba officinalis
after carbonization.
