摘要
采用棒薄层色谱氢火焰TLC/FID法测定了商品粉末磷脂的含量,TLC的展开剂为氯仿:甲醇:乙酸:水(65:20:10:5),各组分变异系数小于12%,在0~30μg范围响应值与点样量成良好线性关系,相关系数大于0.99。
The phospholipid contents of the commerical powdered soybean lecithinwere determined with TLC/FID.The spread solvent of TLC used was chloroform:methnol:acetic acid:water (65 :20:10:5).(Variation coefficient of individual components<12%).The response value of FID within the range of 0~30μg was correlated to theamount of added sample. (correlation coefficient>0.99)
