Abstract: Using Angelica sinensis(oliv.) Diels as raw material, the exrtracting technique of water-sduble and alkali-soluble polysaccharide was studied. Angelica sinensis(oliv.) Diels is first crashed, extracted, precipitating polysaccharide with alcohol, eliminated protein by Sevag, water bacillus and alcohol bacillus. In the end, water-soluble and alkila-soluble polysaccharide of Angelica sinensis(oliv.) Diels can be dried by vacuum freezing. FR-IT proves that the water-soluble and alkila-soluble Angelica sinensis(oliv) Diels have the common traits of some polysaccharide. The best extracting parameter of water-soluble is extracting 4 times with water (1:25) for 3 h. The best exacting ratio is 3.32%. The optimum extracting parameter of alkila -soluble is extracting with NaOH(1:25,1 mol/L) for 6 h. The best exacting ratio is 4.31%.
