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.
