摘要：
Alternative procedures using H2O2 and ultrasound during the alkaline extraction step were applied for the isolation of hemicelluloses from lignified tissues of the industrial grass "Szarvasi-1". The effectiveness of the methods was evaluated by the yield and purity of the isolated hemicelluloses in comparison to classical extraction methods (acidic sodium chlorite delignification, flowed by extraction with 10 % KOH). From the ecological and economical point of view, the ultrasound-assisted extraction (100 W) was the most efficient.
