New Spectrophotometric Methods For The Determination Of Meloxicam
Two Simple and sensitive spectrophotometric methods, A and B have been developed for the determination of meloxicam and its dosage forms. Meloxicam forms stable green coloued chromogen with ferric chloride and potassium fericyanide exhibiting maximum absorption at 770 nm (method A) that shows linearity in concentration of 0.25-2.5 Î¼g/ml. In method B, meloxicam forms blue coloured complex on treatment with Folin Ciocalteu reagent, showing maximum absorption at 740 nm. The chromogen obeys Beer's law in the concentration range of 5-15 Î¼g/ml.
