Title: Optimization of Extraction Conditions of Polyphenols from Longan Flesh
Abstract: Low temperature extraction method using ultra-pure water and different concentrations of methanol,ethanol and acetone as solvent to extract polyphenols from Dimocarpus longan flesh was optimized and compared with traditional heat lixiviation method.The highest extracting amount of polyphenols which was(57.2±0.9) mg per 100 g fresh longan flesh could be obtained by extracting 4 times using 70%(V/V) acetone at low temperature;and it was 18.2% higher than that obtained by heat lxiviation,which was(48.4±1.4) mg per 100 g fresh longan flesh.
