Isolation and Characterization of Oligosaccharides from Honey. Part II. Trisaccharides

SummaryThe trisaccharides melezitose, 3-α-isomaltosylglucose and maltotriose were isolated from honey and characterized as crystalline β-hendecaacetates; 1-kestose and panose as the crystalline sugars and isomaltotriose as the crystalline β-undecabenzoate. Erlose and theanderose (6G-α-glucosylsucrose) were identified by the isolation and characterization of the disaccharides derived on partial hydrolyses. Isopanose, isomaltotetraose and isomaltopentaose were identified by their specific optical rotations and behaviour to acid and enzymic hydrolysis. Evidence is also presented for the presence in honey of two new trisaccharides, namely 2-α-maltosylglucose or 4-α-kojibiosylglucose and the linear 4-α-gentiobiosylglucose. The approximate quantitative composition of these sugars is presented.
