| Abstract: | A acidal polysaccharides isolated from rhodiola sachalinensis A.Bor. was named as RSA. It is consisted of Ara,Rha,Gal,GalA, with the molarity rate of n Ara : n Rha : n Xyl : n Glc : n Gal : n GalA =1.00:3.23:0.26:0.34:0.84:10.24,by means of G.C. Sulfated RSA was obtained with chlorosulfonic acid-pyridine. The sulfur content of the products was found to be 11.01%. The degree of subtitution from 0.85. The IR and UV spectrum, chromatography by sepharose CL-4B, laser desorption ionization time-flight mass spectrometry, RSASL showed characteristic of polysaccharride sulfate respectively. |
