AbstractPaper chromatography of phenols on polyamide impregnated paper was devised. Fourteen phenols in seven different solvents were studied. TheRfvalues were tabulated. The relation between the structure of phenols andRfvalues was discussed. This method was applied for the identification of phenolic constituents ofChamaecyparis formosensis Matum, in wich p‐cresol, o‐cresol and carvacrol were identif
