Determination of methyl salicylate in pharmaceutical preparations

Abstract
A method based on gas-liquid chromatographic technique is described for the determination of methyl salicylate in pharmaceutical preparations. 10% carbowax 20M is used as a stationary phase to resolve mixtures containing amyl, ethyl and methyl salicylates, menthol and camphor. The determinations are based on the area triangulation method against a diphenyl reference standard.
