比色法测定羧甲基茯苓多糖的含量

Colorimetric Metbixl for Determination of Carbexynethyl Pachyman

羧甲基茯苓多糖在浓硫酸存在下与苯酚生成红色物质，反应十分灵敏，颜色稳定。利用这个反应，建立比色法测定羧甲基茯苓多糖含量，并讨论了测定条件。

Carhaxymethyl pachyman gives a red color when treated with phenol and concentrated sulfuric acid.The reaction is sentitive and the color is stable. Based on this reaction ,a colorimetric methed has been developod toanalyse carhaxymethyl pachyman,and some factors that affert the deterinination were discussed.
