摘　　要：以四川省宜宾产苦竹叶为原料,对苦竹叶黄酮的提取工艺进行了研究,确定其提取工艺条件为:以80%的乙醇为提取溶剂,料液比为1∶30,在95℃条件下浸提120 min.将提取液真空浓缩、真空冷冻干燥后制得生物类黄酮含量为30.22%的苦竹叶黄酮浸膏.苦竹叶黄酮浸膏可作为天然添加剂广泛地应用于食品、药品及化妆品生产,具有很好的应用前景.The extracting technology of flavonoids from leaves of Pleioblastus amarus Keng f. collected from Yinbin, Sichuan was studied. The optimum extracting conditions were established as follows： extraction solvent, 80% ethanol; extraction temperature 95 ℃ ; extraction time 120 min, and the ratio of sample to liquid 1 ： 30. An extract preparation of P. amarus flavonoids with a concentration of 30. 22 % was obtained by vacuum-concentrating and vacuum freeze-drying of extract solution. This extract preparation can be used as natural additive in foods, drugs and cosmetics and is highly promising for industrial application.
