G. Bianchi et G. Vlahov, COMPOSITION OF LIPID CLASSES IN THE MORPHOLOGICALLY DIFFERENT PARTS OF THE OLIVE FRUIT, CV CORATINA (OLEA-EUROPAEA LINN) .3., Fett, 96(2), 1994, pp. 72-77
This paper reports on the distribution of ''minor components'' of oliv
e oil in the four parts of olive fruit. The minor components are the n
onglyceridic classes of compounds comprising vegetable oils. It was fo
und that the classes and amounts of minor components varied to a great
extent in the lipid fractions from skin, pulp, wood shell and seed. F
or 100 g of olives the weights of material comprising the minor compon
ents extracted by chloroform-ethanol (95:5) were the following: 103 mg
in the skin, 200 mg in the pulp, 30 mg in the wood shells and 80 mg i
n the seeds. When the minor components were chromatographed by column
chromatography or on thin-layer plates, the following classes of compo
unds were separated: alkanes, alkyl esters, methyl phenyl esters, ster
yl esters, aldehydes, alcohols, sterols, cyclic triterpenoids and very
long chain free fatty acids.
