Simultaneous Determination of 6 Inorganic Anions in Danshen Injection by Ion Chromatography
Objective: An ion chromatography method for simultaneous determination of six inorganic anions(fluoride
formic
chloride
nitrite
bromide and nitrate) in Danshen injection was established. Method: Six inorganic anions were determined by anion exchange column Ion Pac AS11-HC(4 mm×250 mm)
eluted by gradient hydroxide potassium. Result: Good resolution can be achieved among the above mentioned six inorganic anions.Their linear correlations over the investigated concentration were in the range of 0.999 5-0.999 9
while the average recoveries ranged from 90.1% to 106.5%
respectively. Conclusion: The ion chromatography method is fast
accurate
simple
reliable and applicable for the determination and quality control of inorganic anions in Danshen injection.
