摘　　要：用正交试验法对银杏叶中总黄酮的半仿生法提取工艺进行优选。以黄酮提取量为考察指标,考察提取液浓度、提取温度、料液比对总黄酮提取量的影响。得到的半仿生法提取的最佳工艺条件为:提取液浓度80%、提取温度80℃、固液比1∶20(g/mL)。在此条件下,银杏叶总黄酮提取量为6.3468 mg/g。The optimum extraction process was optimized with orthogonal test. Experiments were made by using orthogonal design with extractive yield of total flavonoids as the index, investigating the influence of extracting temperature, extract concentration and the ratio of solid to liquid. Optimum extraction conditions were determined as follows： extract concentration 80%, temperature 80 ℃ stock ratio 1：20（g/mL, mass： volume）. The extractive yield of total flavonoids from ginkgo leaves is 6.3468 mg/g at the optimum parameters.
