Aim To determine the extraction parts of the highest sugar-obtaining rate and measure their polysaccharide percentage.Methods With sugar-obtaining rate of Hippophae Rhamnoides Branches and Leaves as standard,and by using extraction methods such as Ultrasonic auxiliary-Ethanol backflow skim-hot water extraction,to compare sugar-obtaining percentage between water extracts,methanol extracts and ethyl acetate extracts;by using Sevage to remove protein,to adopt Phenol-strong sulfuric acid method to measure the percentage of the total sugar in Hippophae Rhamnoides.Results The percentage of water extracts,methanol extracts and ethyl acetate extracts is respectively 6.42%,4084% and 4.01% and the average percentage of the total sugar in water extracts is 28.51%.Conclusions By using Ultrasonic auxiliary method to extract polysaccharide from Hippophae Rhamnoides,the sugar-obtaining rate is high;the Phenol-strong sulfuric acid method is convenient,sensitive and exact,suitable for measuring the percentage of polysaccharide from Hippophae Rhamnoides.
