ABSTRACT
Objective To determine the content of 5,7-dimethoxycoumarin in Fructus Citris Sarcodactylis. Methods HPLC was used. Mobile phase was methanol-water(65 ∶35),detection wavelength at 326 nm,flow rate 1mL/min and column temperature at 35 ℃.Results The linearity of 5,7-dimethoxycoumarin was in the range of 0.3528~1.7640 ?g. The regression equation was Y=2403.73 X-65.35,r=0.9998. The average recovery was 99.33 %,RSD=1.47 %(n=6). Conclusion The method is simple and accurate. It can be applied in the determination of 5,7-dimethoxycoumarin in Fructus Citris sarcodactylis.
