ABSTRACT
<p><b>OBJECTIVE</b>To establish a quantitative method for determination of synephrine and N-methyltyramine in Citri Reticulatae.</p><p><b>METHOD</b>Samples were extracted with 30% methanol. ODS column was used with methanol-water-sodium dodecyl sulfate (55450.1) as mobile phase. Detection wavelength was 285 nm.</p><p><b>RESULT</b>Synephrine and N-methyltyramine in sample solution were well separated. Linearity of synephrine was good (r = 0.9999) in range of 0.35-11.24 microg. The average recovery was 97.1%, and RSD of repeatability was 1.9%.</p><p><b>CONCLUSION</b>This method can be used for quality control of Citri Reticulatae.</p>
