Abstract

During !he liquid-solid chromatography of monoterpene hydrocarbon mixtures from grapefruit essential oil using silica gel as adsorbent, alterations in the composition of the mixtures were observad by mea ns of gas-liquid chromatography. Column tempera­ture, active sites on dried silica gel and metallic impuri­ties were found to be responsible for a series of isomeri­zation of sorne constituents. lt is.recommeded the use of silica gel 60 extra pu re swith 6,2 % of water, on columns at temperatura below 20 ºC to avoid the isomerizations.
