The rice bran polysaccharide was extracted from defatted rice bran, and the optimal conditions of the experiment were determined. The chemical structure of rice bran polysaccharide was analyzed by IR and C NMR. Three rice bran polysaccharide derivatives were prepared and characterized, namely carboxymethylated rice bran polysaccharide, phosphorylated rice bran polysaccharide, and acetylated rice bran polysaccharide. It showed that the phosphorylated rice bran polysaccharide had good activity.
米糠多糖从脱脂米糠中提取，确定了实验的最佳条件。通过 IR 和 C NMR 分析了米糠多糖的化学结构。制备并表征了三种米糠多糖衍生物，即羧甲基化米糠多糖、磷酸化米糠多糖和乙酰化米糠多糖。结果表明，磷酸化米糠多糖具有较好的活性。
