Abstract

Abstract: The water extraction and ethanol precipitation of polysaccharides from the roots of Cynomorium songaricum Rupr.were optimized by orthogonal array design and the contents of polysaccharides in samples from different habitats in Hexi Corridor were determined by benzenol-H2SO4 method. Results indicated that the optimal extraction conditions were material/liquid ratio of 1:15 (g/mL), refluxing extraction duration of 90 min and repeated extraction number of 2. Root samples of Cynomorium songaricum Rupr. from different habitats in Hexi Corridor were significantly different from each other in their polysaccharide contents. Therefore, polysaccharide content can be used as a quality control indicator for Cynomorium songaricum Rupr..

Key words: Cynomorium songaricum Rupr., polysaccharide, orthogonal test, extraction process, content determination
