Optimal conditions for the extraction of flavones from bamboo leaves were systemically researched by using orthoganol design,and purification conditions were studied by using Macro-reticular resin.The results showed,there were no remarkable difference between abstraction with warm water and ultrasonic technique extraction methods,the optimal conditions for the extraction with warm water bath was 80℃,(30∶1) of 80% ethanol solution to bamboo leaves weight ratio and extracted for 3 hours.From four Macro-reticular resins which all can absorb flavones we finally found that the optimal Macro-reticular resin was AB-8.
