Optimization of Extraction of Lonicera edulis Anthocyanin by Response Surface Methodology

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∶12g/mL,ethanol concentration was 66%,extraction temperature was57℃,extraction time was 92 minutes,under these conditions,the extraction of anthocyanin amount was 328.55mg/100 g.
