Study on the extracting and purifying technology of mango polyphenol

The extraction process of polyphenols from the mango nuclear by using propyl alcohol-ammonium sulfate two-phase separation technology was investigated. The results showed that the optimal extraction conditions of polyphenols from the mango nuclear were as follows: the volume fraction of propyl alcohol to the solution was 60%;the concentration of ammonium sulfate was 0. 35 g / m L; the extraction time was 10 min,and the ratio of the raw material to the extraction solvent was 1∶ 10.
