| Abstract: | Using l50-C ALC/GPC produced by Amehcan waters Cotmpany which is an advanced precise instrument,we have determined the molecular weights and their distrihutions of polysaccharose in astragalus a natural organic substance,From these work we can offer a lot of reliable analytical date for the technological study of separation and extraction of polysaccharose in astragalus upon dif ferent molecular weights and we present a method to determine the characteristic constants of natural organic macromolecular substances. |
