Soluble Sugar Composition of Elaeagnus angustifoliaL. var. orientalis (L.) Kuntze (Russian olive) Fruits

Soluble sugar composition from ethanolic extract of Elaeagnus angustifoliaL. (Russian olive) ( Elaeagnaceae) collected from six different populations in the Gümüshane-Bayburt Valley was determined by gas chromatography. In the fruits, fructose and glu-cose were determined to be the major sugars. The analysis showed the occurrence of fructose and glucose in concentrations (w/w) of 32.62-34.60% and 23.37-24.10% (minimum-maximum), respectively. Sucrose was not detected in mature fruits while fruc-tose and glucose were identified as the major sugars among these populations.
