A Simple Gas Chromatographic Procedure for the Determination of Camphor in Plasma

A simple procedure for analysis of camphor in plasma samples by gas chromatography is presented here. Samples are extracted with hexane containing an internal standard (acetophenone) and, after centrifugation, the hexane layers are concentrated by evaporation, and a small aliquot is injected into the gas chromatograph. Quantitation is achieved by comparison of the peak height ratio of the samples with those of standard solutions. The method displays good sensitivity, linearity, and precision.
