| Abstract: | The extraction of ellagic acid form the fruits of red raspberry using methanol(60%),absolute ethyl,and alcohol hydrochloric acid(1.2mol/L)was studied and acetone was the better solvent.Effects of acetone concentration,ratio of material to liquid,extraction time and extraction temperature on ellagic acid were investigated.Optimum extraction processing parameter was determined as follows:acetone concentration was 85%,ratio of material to liquid was 1g:12mL,extraction time was 90min,extraction temperature was ... |
