| Abstract: | To summarize the technological parameter in ethanol extraction of total Flavones from Eucommia ulmoides Oliv. Leave, such as concentration,temperature, time and so on. The optimum condition by orthogonal design was to extract twice with 12 times of 60% ethanol solution and 1 hour each time. Under the optimum condition the yield reached to 3.08% ,which was 31.9% of solid acquisition. |
