This study was performed to study utilization of separated carbohydrates as well as separation, following analysis of the major components and separation of the carbohydrates in waste liquors of SP, KP, ASAM and AS. The result can be summerized as follows; Inorganic contents in waste liquors increase in this order AS<KP<ASAM<SP. And lignin contents increased in this order : AS<ASAM<KP<SP. Carbohydrate content in the waste liquor shows that AS waste liquor was the highest and SP waste liquor the lowest and those are assumed that the most carbohydrates are modified. Carbohydrate analysis shows that glucose content on the Quercus mongolica was much higher than other wood species. Separation of carbohydrates and lignins is very effective in AS waste liquor. SP waste liguor can be used as a medium additive for mushroom cultivation considering its powerful effect. In the AS waste liquor, waste cooking agent was suitable to recover by the distillation. And wood components was separated by simple treatment. It is possible to produce alditol because of plentiful carbohydrate amount on the waste liquor.
