Analysis of alkaloids in Zanthoxylum nitidum by HPLC-DAD/ESI-Q-TOF-MS / 中国中药杂志

The alkaloids in Zanthoxylum nitidum were identified by HPLC-DAD/ESI-Q-TOF-MS. Separation was performed on a Hanbon C18 column with acetonitrile (with 0.1% formic acid) and water(with 0.1% formic acid) as mobile phase. Based on the high-resolution mass information, MS/MS fragmentation behaviors and chemical components from literatures, 48 components were identified or tentatively characterized including 6 new compounds. This work could be useful for the quality control and further studies of the plant.
