A mixture of[3H]oligosaccharides from various sources with their N-acetlamion-glucositol labelled by 3H at the reduced end has been prepared by hydrazinolysis,Bio-Gel P-2 column chromatography,and NaB 3H4 and NaBH4 reduction.

• 经肼解、Bio－GelP－2柱层析、NaB3H4和NaBH4还原，制备各种来源的、氚标记在还原末端的、还原末端为N－乙酰氨基葡萄糖醇的混合寡糖，经Bio－GelP－4凝胶柱分离，以及用糖苷酸酶解，制备了各种不同类型的氚标记的寡糖。
