Bamboo is a kind of natural lignocellulosic composites, in which cellulose fibers are embedded in a lignin matrix. Cellulose is not only useful as natural fibers, but has the potential to produce valuable chemicals such as ethanol, lactic acid, acetone and butyl alcohol. However, the molecular level utilization of cellulose can be achieved only after separating cellulose and lignin. In this work, bamboo lignocellulosics were converted into carbohydrates and lignophenols under normal pressure and at room temperature using the phase-separation system. The resulting carbohydrates were characterized in comparison with those from woody materials. The cell wall Interpenetrating Polymer Network (IPN) structure of bamboo was looser than woody materials, leading to quick hydrolysis of carbohydrates to monomers, dimmers, trimers and soluble polymer fractions. The sugar compositions from bamboo were similar to those from hardwood. The proportion of low molecular weight sugars was higher than that of woody materials.
