Characterization of Alkali Extracting Polysaccharides from Cultured Cordyceps militaris
Polysaccharides from many sources, catching more and more attention because of their multiple pharmacological activities [1-4], can be extracted by hot water, alkali, and enzyme and so on. In traditional viewpoint, polysaccharides are soluble in water for their hydroxyl and the solubility is the base of its bioactivities while insoluble polysaccharides have low or no bioactivities. The predomin...
متن کاملIsolation and Characterization of Soluble Polysaccharides from Calamagrostis Angustifolia Kom
Sequential treatments of dewaxed Calamagrostis angustifolia Kom with water (60 oC and 90 oC), 70% ethanol, and 70% ethanol containing 0.2%, 1.0%, 2.0%, 4.0%, and 8.0% NaOH at a solid to liquid ratio of 1:25 (g/mL) at 80 oC for 3 h yielded 36.2% soluble polysaccharides of the dry dewaxed material. The eight polysaccharide fractions obtained were comparatively studied by sugar analysis, GPC, FT-I...
متن کاملCharacterization of polysaccharides extracted from spent coffee grounds by alkali pretreatment.
Spent coffee grounds (SCG), obtained during the processing of coffee powder with hot water to make soluble coffee, are the main coffee industry residues and retain approximately seventy percent of the polysaccharides present in the roasted coffee beans. The purpose of this study was to extract polysaccharides from SCG by using an alkali pretreatment with sodium hydroxide at 25°C, and determine ...
متن کاملEffects of Dimethyl Sulfoxide on Neuronal Response Characteristics in Deep Layers of Rat Barrel Cortex
Introduction: Dimethyl sulfoxide (DMSO) is a chemical often used as a solvent for waterinsoluble drugs. In this study, we evaluated the effect of intracerebroventricular (ICV) administration of DMSO on neural response characteristics (in 1200–1500 μm depth) of the rat barrel cortex. Methods: DMSO solution was prepared in 10% v/v concentration and injected into the later...
متن کاملIsolation and Characterization of Soluble Polysaccharides of Dendrocalamus Brandisii: a High-yielding Bamboo Species
Nine soluble polysaccharide fractions were sequentially extracted with hot water at 80, 100, and 120 °C for 3 h, and 60% aqueous ethanol containing 0.25, 0.50, 1.00, 2.00, 3.00, and 5.00% NaOH at 80 °C for 3 h from dewaxed bamboo (Dendrocalamus brandisii) sample, and their chemical compositions and physicochemical properties were examined. The sequential treatments yielded 20.6% soluble polysac...
