Abstract: In this study, pilot extraction polysaccharides and flavonoids from moso bamboo leaves and stemes were discussed. By adding different enzymes in pilot extraction processes, effects on the extraction ratio and purification were discussed, furthermore, optimal alcohol concentration of flavonoids extraction was studied by changing alcohol content. The results showed that: proper addition of cellulase can increase the extraction rates and purities of polysaccharides and flavonoids from moso bamboo leaves and stemes, remarkably, and the ideal alcohol concentration of flavonoids extraction is 30%～50%.

Key words: biological enzyme, moso bamboo leaves and stems, polysaccharides, flavonoids, pilot extraction
