摘 要 目的:建立全面、快速分析苗药云实皮化学成分的方法,为该药质量控制和药效物质基础研究提供参考。方法:采用超高
效液相色谱-四极杆-飞行时间串联质谱联用技术(UPLC-Q-TOF-MS/MS)。色谱柱为 Agilent SB-C18,流动相为 0.1%甲酸水溶
液-0.1%甲酸乙腈溶液(梯度洗脱),流速为0.25 mL/min,柱温为30 ℃,进样量为2 µL;电喷雾离子源,正、负离子模式全程扫描,扫
描范围为m/z 50~1 500,毛细管电压为4.5 kV,雾化气(氮气)压力为1.2 Bar,去溶剂气为氮气,去溶剂气流速为8 L/min,去溶剂气
温度为 200 ℃。使用 Data Analysis 4.2 软件分析各成分峰的碎片离子信息,结合相关文献和对照品质谱图指认云实皮的化学成
分。结果:在正离子模式下,共确定并指认9个化合物,峰1、2、3、4、5、6、7、8、9分别为儿茶素、原苏木素B、表儿茶素、没食子酸乙
酯、槲皮素、木犀草素、3-去氧苏木查耳酮、异甘草素、亚油酸;在负离子模式下,共确定21个色谱峰,并指认了其中13个,峰3、4、5、
6、7、8、9、10、11、12、13、15、21分别为儿茶素、短叶苏木酚酸、原苏木素B、表儿茶素、没食子酸乙酯、表儿茶素没食子酸酯、槲皮素、
白藜芦醇、苏木查耳酮、木犀草素、3-去氧苏木查耳酮、异甘草素、亚油酸。结论:成功建立了可分析云实皮化学成分的
UPLC-Q-TOF-MS/MS法。

ABSTRACT OBJECTIVE:To establish a method that can comprehensively and rapidly analyze the chemical compositions of
Miao medicine Caesalpinia decapetala,and to providing reference for quality control and pharmacodynamic material basis study of
C. decapetala. METHODS:UPLC-Q-TOF-MS/MS was adopted. The determination was performed on Agilent SB-C18 column with
mobile phase consisted of 0.1% formic acid solution-0.1% formic acid acetonitrile(gradient elution)at the flow rate of 0.25 mL/min.
The column temperature was 30 ℃,and sample size was 2 µL. ESI source was applied in negative and positive scanning ion mode
and data collection range of m/z 50-1 500. The capillary voltage was 4.5 kV,the atomizing gas(nitrogen)pressure was 1.2 Bar,
the solvent removal gas was nitrogen,the flow rate of solvent removal gas was 8 L/min and the solvent removal gas temperature
was 200 ℃. Data Analysis 4.2 software was adopted to analyze fragment ion information of each peak,and identify chemical
compositions on the basis of relevant literature and mass spectograms of reference substance. RESULTS:Under positive ion mode,
9 chemical compounds were identified;peak 1,2,3,4,5,6,7,8,9 were catechin,protohematoxylin B,epicatechin,ethyl
gallate, quercetin, luteolin, 3-deoxy-hematoxylin chalcone,
