Optimization of the Extraction Technology of Eupolyphaga sinensis Polysaccharide
摘要
Abstract
[ Objective ] To extract Eupolyphaga sinensis polysaccharide through experiment for the research and development of polysaccharides in traditional Chinese medicine. [ Method] The Eupqlyphaga sinensis polysaccharides were extracted by hot water, and the extraction conditions were determined by single factor test, an orthogonal experiment was carried out with the four factors of extraction time, solid-liquid ratio, extraction temperature and extraction times, the polysaccharides content was determined using phenol-sulfuric acid. [ Result] Extraction temperature had the largest impact on the extraction of Eupolyphaga sinensis polysaccharides, then followed by extraction time, extraction time and solid-liquid ratio. The optimal extraction conditions were 1.5 h of extraction time, l:10(g/ml) of solid-liquid ratio, 80 X of extraction temperature , and three times of extraction. [ Conclusion] The main factors influencing the extraction of insect water soluble polysaccharides included extraction temperature, extraction time, extraction times and solid-liquid ratio. With the prolonging extraction time, the cells disrupted completely , more polysaccharide was dissolved out, and the polysaccharides content improved.关键词
