The infrared spectrometric determination of safrole in red camphor oils was disturbed by the ovelapping absorption bands of the coexisting components. This made the selection of the key band quite difficult and hinder the direct application of the I. R. spectrometry. The pretreatments of the sample including, thin layer chromatography and silica gel chromatography for removing interfering components was investigated, in which successive variation of developing solvents enabled the quantitative separation of safrole. Taking the absorption 1040 cm-1 of safrole and 1380 cm-1 of n-hexane usually remaining in the safrole fraction of the eluate as the key bands, the amount of safrole was determined accurately on the above two component system.
