Method of detection of allicin homologues was investigated by means of paper partition chromatography. The results were as follows : 1) Iodine-azide, sodium nitroprusside and phosphomolybdenic acid reagents were suitable for the coloration of allicin homologues. Allyl radical of allicin homologues was colored by phloroglucin reagent. 2) Petroleum ether saturated with 95% methanol was best suited for the paper chromatography of [chemical formula] as the developing solvent, and the mixture of methanol and benzene (3 : 2) for that of [chemical formula]. 3) Cysteine was added to the extract of each spot on the paper chromatogram of [chemical formula] and these reactive liquids were submitted to paper chromatography with the upper layer of the mixture of butanol, ethanol, acetic acid and water (4 : 1 : 1 : 10) as the developing solvent. Alkyl radical of each spot on paper dhromatogram of [chemical formula] was confirmed by this method.
