SHMP-assisted Extraction of Polyphenols from Eggplant and Its Antioxidation in Vitro
Sodium hexametaphosphate-assisted extraction was applied to extract polyphenols from eggplant pulp. By means of DPS design with three factors (extraction time, alcohol concentration and extraction time) as influence factors, the optimal extraction technology was performed. The results showed that (1 )the optimal parameters for the extraction were using 50% ethanol as impregnate, 0.6% sodium hexametahposphate (SHMP) as auxilliary extractant, extraction time is 140min. (2)Compared with VC, reductive ability and scavenging DPPH· activity of polyphenols extracts were studied,results showed that polyphenols extracts has higher antioxidant activity. The polyphenols of eggplant showed high anti-ox-idative activity in vitro, which is a kind of valuable plant resources.
