Gas-chromatographic analyses of capsaicin and its homologue

Abstract

A method for the qualitative determination of capsaicin and its homologue by means of gaschromatography is described. Capsaicin and its homologue can be also completely converted to trimethylsilyl ethers by the reaction with equivalent amounts of trimethylchlorosilane and hexamethyldisilazane.
Relative retention time data are given for capsaicin homologue and its trimethylsilyl ethers on Silicone GE SF-96 column using hydrogen flame ionization detector.
