ABSTRACT

0.999 9).The minimum quantitative concentrations were 0.027 ?g?mL-1,0.033 ?g?mL-1,0.095 ?g?mL-1,respectively.The 3 kinds of organic solvents were not found in each batch except 0.10% and 0.15% ethyl acetate was found in 2 batches of samples.CONCLUSIONS:The established method is accurate,sensitive and accurate for the determination of 3 kinds of residual organic solvents in beclometasone dipropionate simultaneously.
