Abstract：Rhubarb polysaccharides are water soluble active components extracted from Radix et Rhizoma Rhei. In this paper, we reviewed the extracting and purifying methods, analysis methods, and pharmacological effects of rhubarb polysaccharides. At present, common methods for extracting and purifying are extraction with water, precipitation with alcohol, removal of protein, and ultrafiltration. The common analysis methods for rhubarb polysaccharides are sulfuric acid-phenol method, sulfuric acid-carbazole method, gas chromatography method and high performance capillary electrophoresis. Related studies also show that rhubarb polysaccharides possess important biological activities, such as reducing blood sugar, relieving liver injury, treating stress-induced ulcer, anti-tumor, enhancing immunity, anti-aging, anti-thrombotic and treating cardio-cerebral vascular disease.
