Abstract:: Taking Lonicera edulis anthocyanin as material，with absorbance as evaluation indexes，the influence of ethanol concentration，solid-liquid ratio，extraction time，extraction temperature to the extraction amount of Lonicera edulis anthocyanin were studied，the optimum extraction conditions were determined by response surface methodology.The results showed that the solid-liquid ratio was 1∶12 g/mL，ethanol concentration was 66%，extraction temperature was 57℃，extraction time was 92 minutes，under these conditions，the extraction of anthocyanin amount was 328.55 mg/100g.
