Isolation and Characterization of a Pure Mannan from Oncidium (cv. Gower Ramsey) Current Pseudobulb during Initial Inflorescence Development
A water-soluble and neutral polysaccharide was extracted from the current pseudobulbs of <I>Oncidium</I> "Gower Ramsey" during the early inflorescence stage (flower stalk less than 4 cm) by hot water, precipitated with ethanol, and purified with an anion exchanger. From the data of monosaccharide composition and linkage and anomeric configuration analyses, the polysaccharide was identified as a linear β-1→4 linked mannan.
