Determination of Three Compenents in Antodine Injection With Partial Least Square Method / 中国药房

OBJECTIVE:To determine aminophenazone,phenazone and barbital in antodine injection.METHODS:Taking 0.1mol/L NaOH as solvent,the detection data was caculated with partial least square method.RESULTS:The average recoveries were 99.7% for aminophenazone(RSD=0.67%),99.1% for phenazone(RSD=0.76%) and 99.5% for barbital(RSD=0.72%).CONCLUSION:The method is simple,rapid and good in repeatability.
