This method is based on the reaction of the drug with ferric chloride and potassium ferricyanide, giving a green-colored chromogen exhibiting maximum absorbance at 791 nm against reagent blank. Beer’s law was obeyed in the concentration range of 1-6 μg/ml. Results of the analysis were validated statistically<br />and by recovery studies.<br /><br />}, number={2}, journal={Asian Journal of Pharmaceutics (AJP)}, author={Priyanka, P and Suresh1, P}, year={2014}, month={Aug.} }
