| Abstract: | With the marigold stems as raw material,this experiment adopted the method of immersion extraction to extract polysaccharides,and used the method of phenol-sulfuric acid to determine the content of polysaccharides.The effect of immersion extraction temperature,pH value,ratio of material to liquid and extraction time on the extraction rate of polysaccharide was studied.The optimal condition was as follows:ratio of materials to liquid was 1 ∶ 20,temperature was 85 ℃,extraction time was 3 h,the pH was 6.0 and extracting one times,the extraction rate was 10.21%. |
