Abstract

OBJECTIVE

To establish a quantitative method for determination of synephrine and N-methyltyramine in Citri Reticulatae.

METHOD

Samples were extracted with 30% methanol. ODS column was used with methanol-water-sodium dodecyl sulfate (55:45:0.1) as mobile phase. Detection wavelength was 285 nm.

RESULT

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%.

CONCLUSION

This method can be used for quality control of Citri Reticulatae.
