ABstract – Detection of halofantrine, mefloquine…

ABSTRACT

A complexation phenomenon between certain antimalarials (as donors) and chloranilic acid (as an acceptor) has been studied using thin-layer-chromatography (TLC). The antimalarials were subjected to charge–transfer complexation using chloranilic acid as the pi-acceptor. This technique was used for the qualitative detection of the drugs. Drug-spotted TLC plates, when developed in suitable solvent systems and sprayed with the pi-acceptor gave a spontaneous purple colour. The Rr values of the three drugs were found to be constant and specific for each drug sample in a particular solvent system.
