Objective To establish a method for determination of polysaccharide from the leaves of Sorbus tianschanica Rupr.and its bacteriostatic action. Methods Phenol-sulfuric acid method was used for extraction and determination of polysaccharides in Sorbus tianschanica Rupr. Its antibacterial action was studied by control experiment. Results Average content of polysaccharides in Sorbus tianschanica Rupr was 2.56%.The polysaccharides exerted bacteriostatic effect, especially on Bacillus subtilis. Conclusion The method is simple and accurate, and can provide theoretical basis and reference for relative research of Sorbus tianschanica Rupr.
