摘要:

独活(Angelicae Pubescentis Radix)作为一种被广泛应用的中药, 常用于治疗风湿性疾病。本研究通过运用UPLC-Q-TOF-MS液质联用技术定性分析独活提取物中的化学成分。独活提取物的分离通过Agilent SB-C18色谱柱(1.8 μm, 2.1 mm×50 mm)经梯度洗脱完成, 流动相由0.1%甲酸水和乙腈组成。通过配有ESI电离源的质谱仪在m/z 100–800全扫描正离子模式下进行数据采集。通过比较一级和二级质谱数据, 共鉴定出49个化合物, 包括46个香豆素类和3个非香豆素类化合物。其中2个化合物被鉴定为新化合物, isoangenomalin, scoparone, 4-methyl-umbelliferyl acetate, suberenol, trans-dehydroostholoroselone为首次在独活中发现的化合物。

Abstract:

Angelicae Pubescentis Radix(APR, Duhuo) is a commonly used traditional Chinese medicine and usually used for the treatments of rheumatic diseases. To assess the chemical composition of APR extract, a sensitive and reliable UPLC-Q-TOF-MS method was used for qualitative analysis. The separation was achieved on an Agilent SB-C18 column (1.8 μm, 2.1 mm×50 mm) with a gradient elution system consisting of acetonitrile and water containing 0.1% formic acid. An electrospray ionization (ESI) was used for mass spectrometer, and the data were collected in the positive ion mode, which was operated in a full-scan mode at m/z 100–800. A total of 49 compounds including 46 coumarins were identified according to the MS and MS/MS data. Among them, two were new compounds, and isoangenomalin, scoparone, 4-methyl-umbelliferyl acetate, suberenol, trans-dehydroosthol, and oroselone were first reported in APR.
