摘要: 比较了10个竹叶品种的黄酮含量和风味差异,并采用热水提取和乙醇提取两种方法,用正交试验筛选出最佳工艺参数。试验结果表明:斑竹、慈竹和紫竹黄酮含量较高,筱竹和麻竹风味较佳。正交试验提出最佳工艺参数,即热水提取的最佳工艺配比是提取时间30 min、提取温度80℃、料液比例20倍;乙醇提取法的黄酮浸出量明显高于水提法,乙醇提取的最佳工艺配比是乙醇浓度80%、提取时间20 min、料液比例20倍。

Abstract: Based on the comparison of the flavonoids contents and flavors of bamboo leaves from 10 bamboo varieties, orthogonal test was employed to optimize the technologic parameters of extracting flavonoids from bamboo leaves by hot water and ethanol in this paper. The results show that the flavonoids contents of bamboo leaves from Phyllostachys bambusoides f. lecrima-deae keng f. et Wen, Neosinocalamas affinis(Rendle) Keng f. and Phyllostachys nigra(Lodd) munro are much higher, whereas the flavors of Thamnocmus spathaceus(France) Sod. and Dendrocalamus latiflorus Munro are better. The extraction conditions are optimized, that is, a quotient of raw material is extracted by 20 quotients hot water at 80℃ for 30 min. The efficiency of extracting by ethanol is better than that of by hot water, and its optimum conditions are a quotient of raw material extracted by 20 quotients 80% ethanol for 30min.

Key words: bamboo leaves, flavonoids, extracting, orthogonal test
