紫外分光光度法测定南天竹茎、叶多糖含量

Determination of the Polysaccharide Content in Nandina Domestica Stem and Leaf by UV spectrophotometry

以葡萄糖为标准样品,用紫外分光光度法测定南天竹茎、叶多糖含量,并考察了不同浓度的乙醇、不同提取温度对多糖含量的影响。结果表明,该方法操作简单,重复性好,结果准确可靠,可用于南天竹茎、叶多糖含量测定。

Using Glucose as the standard sample, the Polysaccharide Content in Nandina Domestica Fruit, Stem and Leaf is determined using UV - spectrophotometry, and examines the different concentrations of ethanol extraction temperature on the influence of the content of polysaccharide. It shows that The UV - spectrophotometry method is simple, accurate and sensitive, which can be used as a method for the Polysaccharide in Nandina Domestica Stem and Leaf.
