摘　　要：研究了甘露醇含量的分光光度测定法 ,测定下限为 2 0 μg/m L;线性回归方程 y=1 4.2 58x- 6× 1 0 -3,相关系数为 0 .9999;1 0倍量葡萄糖基本无干扰 ;血清中的加标回收率为 99.4%。An effective method to determine content of mannitol in biological fluid and preparation by spectrophotometry was studied. The linear regression equation of working curve is y =14 258 x -0.0066,with R 2=0.9999. The recovery rate is 99.4%. Glucose with 10 times concentration did not interfere the determination. The stability and reproducibility were good.
