ABSTRACT
<p><b>OBJECTIVE</b>To investigate the flavonoids in Platycladi Cacumen.</p><p><b>METHOD</b>The constituents in Platycladi Cacumen were determined by UPLC-MS. A Waters BEH C18 column (2.1 mm x 150 mm, 1.7 microm) was used with a gradient elution of methanol-water containing 0.2% formic acid. The mass spectrometer equipped with electrospay ionization source was used as defector and operated in data was collected under the negative ion modes.</p><p><b>RESULT</b>Eleven constituents were identified.</p><p><b>CONCLUSION</b>In this study, the main flavonoids in Platycladi Cacumen were separated by UPLC, and identified through the information of mass number and UV spectra. With the information of MS/MS from flavonoids, the modes of breaking up flavonoids were discussed. It is an accurate and effective method which can be applied for the constituent identification of Platycladi Cacumen.</p>
