Chromatographic methods for simultaneous determination of diiodohydroxyquinoline and Metronidazole in their binary mixture
Journal Title: Pakistan Journal of Pharmaceutical Sciences - Year 2013, Vol 26, Issue 5
Abstract
Two chromatographic methods were developed for analysis ofdiiodohydroxyquinoline (DIHQ) and metronidazole (MTN). In the first method, diiodohydroxyquinoline and metronidazole were separated on TLC silica gel 60F254 plate using chloroform: acetone: glacial acetic acid (7.5: 2.5: 0.1, by volume) as mobile phase. The obtained bands were then scanned at 254 nm. The second method is a RP-HPLC method in which diiodohydroxyquinoline and metronidazole were separated on a reversed-phase C18 column using water : methanol (60 :40, V/V, PH=3.6 )as mobile phase at a flow rate of 0.7 mL.min-1 and UV detection at 220 nm. The mentioned methods were successfully used for determination of diiodohydroxyquinoline and metronidazole in pure form and in their pharmaceutical formulation.
