摘　　要：目的：建立锁阳多糖咀嚼片中粗多糖含量的测定方法。方法：浓H2SO4水解,4%苯酚溶液显色后,分光光度法测定锁阳多糖咀嚼片中粗多糖含量。结果：锁阳多糖咀嚼片中粗多糖含量测定方法的线性方程为：y=57.317x-0.0114,相关系数为0.9983,线性范围为0.0030~0.0135mg/m L,精密度2.14%,加标回收率为98.97~102.13%。结论：该方法简单、准确,可用于锁阳多糖咀嚼片中粗多糖的测定。Objective： Exploring a efficient method for determining contents of polysaccharide in Cynomorium Songaricum chewable tablets by spectrophotometry. Method： glucose as control article, the content of the polysaccharide in Cynomorium Songaricum＇s chewable tablets was determined by spectrophotometry. Results： The linear equation, related coefficient and range of linearity were y=57.317x-0.0114, r=0.9983, 0.0030~0.0135 mg/m L, respectively. The precision（RSD） was 2.14%. The recoveries obtained were from 98.97 to 102.13%. Conclusion： The method was linear and sensitive for the determination of polysaccharide in Cynomorium Songaricum＇s chewable tablets.
