ABSTRACT

OBJECTIVE:

To establish a method for the identification and content determination of leguminosae in Qizhu bishi granules.

METHODS:

Thin layer chromatography (TLC) was used to identify the leguminosae. HPLC-ELSD was used to deter-mine the content of astragaloside A in leguminosae. The column was Diamonsil C18 with the mobile phase of acetonitrile-water(32∶68,V/V)at the flow rate of 1.0 ml/min,the column temperature was 40 ℃. The sample size was 20 μl. The drift tube temperature was 108 ℃ with the nitrogen gas flow rate of 2.8 ml/min.

RESULTS:

The TLC features of leguminosae were obvious with clear spots and good specificity. Astragaloside A had a good linear relationship in the range of 0.402 4-4.02 μg(r=0.997 0). RSDs of pre-cision,stability and reproducibility tests were≤0.8%. The average recovery was 99.00%(RSD=1.29%,n=9).

CONCLUSIONS:

The method is simple,accurate and reliable and can be used for the quality control of Qizhu bishi granules.
