摘　　要：丝瓜叶中含有丰富的黄酮类化合物。采用分光光度法,以芦丁为标准品,测定丝瓜叶中总黄酮的含量。结果显示:乙醇提取法最佳工艺组合为A1B3C3D3,即乙醇浓度30%,提取时间3h,料液比1g∶50mL,提取温度60℃。研究结果可为利用丝瓜叶工业化生产黄酮类药用成分提供科学依据。Leaves of pumpkin are rich of fiavonoids compounds. Flavonoids in pumpkin leaves was determined by spectrometric method with rutin as a standard. The results indicated that; the optimized extracting condition of the ethanol digest method was A1 B3C3D3, which was adding twenty times amount of the ethanol 30% ,etracting time3h,solid -iquid ratio1 g ： 50mL and temperature of extraction 60℃. This data provided useful information of flavonoids from pumpkin leaves.
