The best level of the factors including extraction te mperature , extraction time, ethanol concentration and the ratio of weight of the dry leaf powder to volume of solvent (W/V) were determined in extraction of flavone from Lonicera maackii Maxim. The optimal processing techniques foun d through orthogonal experiment was that the dry leaf powder was soaked with 60% of ethanol at 1∶30 of W/V for 4 hours at 70℃, in which 95 per cent of the tot al flavone in the leaves would be extracted after two times.
