ABSTRACT

OBJECTIVE:

To establish a method for the content determination of sinomenine in Qihuang capsule.

METHODS:

HPLC was performed on the column of welch C18-AQ with mobile phase of methanol-phosphate buffer(gradient elution) at flow rate of 1.0 ml/min,detection wavelength was 264 nm,column temperature was 30 ℃ and volume injection was 10 μl.

RESULTS:

The linear range of sinomenine was 0.200 3-10.016 0 μg(r=0.999 8),RSDs of precision,stability and reproducibility tests were lower than 1.0%,recovery was 98.80%-100.94%(RSD=0.79%,n=6).

CONCLUSIONS:

The method is simple,accurate and re-producible,and can be used for the content determination of sinomenine in Qihuang capsule.
