[Determination and identification of unsaturated hydrocarbons in sunflower oil]

The procedure has been described for determination of unsaturated hydrocarbons in sun flower oil by ligand exchange chromatography. 15 compounds including sesequiterpenes and diterpenes (the latter ones predominated) have been identified in the olefin fraction. Compounds similar to gurjunen and cadinen isomers dominated in the series of sesquiterpene hydrocarbons whereas compounds of the labdan and cauren types were predominant among diterpene hydrocarbons.
