摘　　要：对苦竹类竹叶总黄酮的提取工艺进行了研究,确定了乙醇超声提取法的最佳提取工艺是:75%乙醇,1∶15料液比,超声提取3次,每次20min。采用比色法测定苦竹类竹种的总黄酮质量分数,结果表明苦竹类竹种均含有丰富的黄酮类物质,其中小黄苦竹Oligostachyumfujinensis含总黄酮质量分数最高,为13 54mg·g-1,短穗竹(俗名苦竹)Semiarundinariadensiflora最低,为7 24mg·g-1。Techniques for extraction of total flavones from leaves of Ku bamboos were studied.The best alcohol-UW extracting method was as follows:leaves∶extraction liquid(75% alcohol)=1∶15;UW extracting for three times and 20 minutes each time.Toal flavones contents of Ku bamboo relative species were measured with the colorimetric method.The results indicated that Ku bamboo relative species were rich in total flavones,of which Oligostachyum fujinensis was highest in the content of flavones(13.54 mg·g^(-1))and Semiarundinaria densiflora was the lowest (7.24 mg·g^(-1)).
