A new rapid method of two step precipitation for isolation of alkali-soluble lignins with relatively free of polysaccharides from wheat straw was proposed in this study. The isolated alkali-soluble lignin fractions LA contained rather low amounts of neutral sugars (0.7-1.0%) and had low average mole

The utilization of various alkaline regimes for the optimal extraction and isolation of hemicellulose and cellulose from wheat straw was extensively examined. Factors investigated include varying concentrations of one alkali (KOH) and varying temperature and time of extraction, and varying the natur
