ABSTRACT
OBJECTIVE:
To establish a method for the determination of residuals of petroleum ether,ethanol,xylene and ace-tic acid in ecabet sodium crude drug.METHODS:
Capillary GC was performed on the column of PGE-20M capillary column at the flow rate of 1.7 ml/min,detector was hydrogen flame ionization detector,carrier gas was nitrogen with high purity,column temper-ature was 45 ℃,maintaining 4 min,it increased to 80 ℃ with rate of 10 ℃/min,then increased to 135 ℃ with rate of 30 ℃/min,maintaining 3 min,the injection mode was direct injection,inlet temperature was 250 ℃,and the volume injection was 1.0 μl.RESULTS:
The mass concentration was 0.050-1.952 g/L for petroleum ether,0.050-1.941 g/L for ethanol,0.024-0.948 g/L for xy-lene and 0.050-1.947g/L for acetic acid(r=0.999 1-0.999 7);RSDs of precision,stability and reproducibility tests were no more than 1.7%;recoveries were 99.3%-101.0%(RSD=0.7%,n=9),102.3%-103.7%(RSD=0.4%,n=9),101.2%-102.1%(RSD=0.3%,n=9) and 100.3%-102.2%(RSD=0.6%,n=9),respectively.CONCLUSIONS:
The method is simple and accurate,and can be used for the control of residual of organic solvents in ecabet sodium crude drug.
