ompared with some solvent on powder of bamboo leaves flavonoids extraction and study on concentration, temperature, solvent extraction, solid-liquid ratio and other factors influence on the extraction of flavonoids. Tests show that bamboo optimum extracting conditions of flavonoids from bamboo leaves in powder form as: acetone concentrations 40%, 2 h, 1:20 solid-liquid ratio, temperature of 60 degrees centigrade. The size of the various factors influencing the extraction of bamboo leaf flavones were: acetone concentration of solid-liquid ratio temperature. Soxhlet extraction rate of flavonoids obtained higher than extraction. Natural drying rate of bamboo leaves extract than freeze drying rate of bamboo leaves extract.
