摘要
本文用电化学差示脉冲伏安法,分别以甘露糖、葡萄糖、半乳糖和果糖为标准品,测定库拉索芦荟凝胶多糖的含量。研究表明以这四种不同的单糖做标准,其检测结果无显著性差别,均可以采用,平均回收率为107.9%,RSD为2.4%,检出限为2.09ug/ml。
This paper reported the determination of polysaccharide from Aloe barbadensis Miller by different poulse voham- metry using mannose, glucose, galactose and fructose as reference substances. The results showed no significant difference when the four different monosaccharides were used as reference substances respectively. The average recovery was 107.9%, RSD=2.4%, and the detection limit was 2.09 ug/mL.
