Abstract: The extraction process of total flavonoids from bamboo leaves by the ethanol was studied.Based on single factor test,response surface methodology(RSM) was used to study effects of extraction time,ethanol concentration and solid-liquid ratio on extraction rate of total flavonoids.The results showed that the optimal extraction conditions of total flavonoids from bamboo leaves are extraction temperature 83.02 ℃,ethanol concentration 85.78% and solid-liquid ratio 124.23.In this case,the extraction rate of total flavonoids from bamboo leaf reaches 2.08 %。
