STUDIES ON WATER SOLUBLE SUGAR AND SUGAR ALCOHOL IN CULTIVARS AND WILD FORMS OF LAUROCERASUS OFFICINALIS ROEM., F. AHMET AYAZ Abstract: Water soluble sugar and sugar alcohol composition in fruits of Laurocerasus officinalis cvs. Oxygemmis, Globigemmis and wild form of L. officinalis Roem., have been examined. Gas chromatography-mass spectrometry studies exhibited that the main sugars in L. officinalis and related cultivars are fructose, glucose and sorbitol and sorbitol and mannitol as sugar alcohols. Fructose, glucose and sorbitol were in significantly higher levels in cultivars and the wild form with highest value 74.4% of dry weight of total water soluble sugar in Oxygemmis and the highest level of sugar alcohol (42.6%) in the wild form with least in Angustifolia (19.9% of dry weight).
