RESUMEN
A rapid and specific high performance liquid chromatography-mass spectrometric method was developed for determination of magnoflorine in Rhizoma Coptidis and Cortex Phellodendri Chinensis. Samples were extracted by methanol. Agilent Eclipse XDB-C18 ODS column (4.6 mm x 150 mm, 5 microm) was used, and mobile phase was methanol-water (60:40) at a flow rate of 0.8 mL x min(-1). Electrospray ionization model (ESI), and MRM model were used for quantification. The linear range of magnoflorine was 4.352-2720 microg x L(-1). The average recovery was above 98%. The method is simple, sensitive and accurate, it can be used for determination of magnoflorine in Rhizoma Coptidis and Cortex Phellodendri Chinensis.
