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-reticu...
竹叶又称淡竹叶,为禾本科植物淡竹(Phyl-lostachys nigra(Lodd.)Munrovar.henonis(Mitf).Stapf ex Rendle)的叶.竹叶在我国有很悠久的食用和药用历史.最新的研究结果表明,竹叶中含有大量的黄酮类化合物和具有生物活性的多糖等有效成分,另外竹叶中酚酸类化合物、蒽醌类化合物、?
