Abstract A thin-layer chromatography (TLC) method with scanning is described for evaluation of the 1,8-cineole content of Eucalyptus essential oils. Samples were developed on silica gel G 60 with light petroleum–chloroform (70 + 30) as mobile phase. Color was developed with 4-dimethylaminobenzal-dehyde–sulfuric acid reagent. The absorbance of colored spots was measured at 460 nm. The response was linear between 15 to 75 μg of 1,8-cineole, with a correlation coefficient of 0.9997. The results of each assay were compared with those from gas–liquid chromatography (GLC). The TLC to GLC ratio was constant (0.92).
