摘要
用高效薄层扫描法，以正丙醇：浓氨水：术（１２：４：１）为展层剂，在λ＝３００ｎｍ处同时测定乳粉中乳糖、蔗糖，用该法测定乳糖与蔗糖回收率分别为１００．４％和１０４．５％，变异系数分别为３．２３％和１．５１％．
This paper reports about determining lactose and sucrose in milk powder atthe 300um wavelength, simultaneously, by high performance thin-layer chromatographyscanning technique,using developing solvent of n- propanol -aqua ammonia-water(12:4: 1).In doing so,the rate of recovery is 103.5%and 100.4%,and the coefficient of variation is 3.23%and 1.51 %for lactose and sucrose, respectively.
