摘要
目的研究灵芝孢子粉胶囊中灵芝多糖含量测定法。方法采用紫外分光光度法对灵芝孢子粉胶囊中灵芝多糖含量测定。结果灵芝多糖在波长为487nm处有最大吸收。本法准确,精密度高,重现性好。葡萄糖浓度在2.864~11.456μg·mL-1(r=0.9995)范围内、线性关系良好,平均回收率在10.3%,RSD为1.9%。结论该法可作为灵芝孢子粉胶囊质量控制的一种方法。
To develop a method for content determination of polysaccharides in spore powder of Lucid ganderma capsules. Method The content of polysaccharides was determined by UV. There was the best absorption wavelength at 487 nm. Result The linear relationship of polysacchariders concentration was at the range of 2. 864~11. 456 mg · mL^-1 (r=0.9995)the average recovery of 100.3% and RSD was 1.9%. Conclusion This method was accurate,simple and reproducible,and can be used for quality control of spore powder of Lucid ganderma capsules.
