摘要：

Water-soluble polysaccharides from Sophora flavescens (Fabaceae) roots were studied. The dominant polymer S_f P-1-1/2 of molecular weight 85 kDa was isolated using ion-exchange and gel chromatography. The structure of the isolated compound was α-(1→4)-glucan partially substituted at the C-6 position by single glucopyranose units. A pharmacological study showed that S_f P-1-1/2 exhibited under azathioprine suppression pronounced immunostimulating activity.
