Objective To investigate the antioxidant function of Brassica rapa L. polysaccharide and processing technology of its tablet. Methods The crude polysaccharides of Brassica rapa L. were extracted by the method of water extraction and alcohol precipitation. The method of Savege was used to remove protein, and activated carbon was used to decolorize and purify the polysaccharides. Two groups of antioxidant experiments were carried out by using the extracted Brassica rapa L. polysaccharide. In order to determine the optimum molding process, the single factor method was used to select the adhesives, fillers, disintegrants and lubricants to prepare Brassica rapa L. polysaccharide tablets. Results Brassica rapa L. polysaccharide had good antioxidant activities. The optimum conditions of molding process were as follow: 80% ethanol was the adhesive, lactose was the filler, 5% dosage of CMS-Na was disintegrating agent and magnesium stearate was the lubricant. Conclusion Brassica rapa L. polysaccharide has good antioxidant activities, which lays the foundation for the development of natural immune regulator for further use of the traditional Uyghur medicine and food materials.
