| Abstract: | A simple and effective procedure for the comparative chromatography of 1–2 ml of essential oils on a 40×250 mm column of silica gel with gradient elution by hexane-diethyl ether has been developed. A simple system of preparing the mobile phase permits the creation of a continuous gradient during chromatography. The efficacy of the procedure has been shown taking as an example the isolation of fenchone from fennel essential oil. A. V.
