Abstract:
In order to evaluate antioxidant activity in vitro of procyanidins from pericarp of four cultivars (Baila, Feizixiao, Nuomizi, Huaizhi) of litchi (LPPC), superoxide anion radical, hydroxyl radical and hydrogen peroxide scavenging assays were carried out using pyrogallo-luminol, ferrous sulfate-Luminol-hydrogen peroxide and Luminol-hydrogen peroxide systems, respectively. In addition, copper sulfate-phen-VC-hydrogen peroxide-DNA system was used to determine the preventing effect of LPPC against DNA damage. Results showed that among the litchi cultivars, Baila LPPC possessed the best scavenging potency against superoxide anion and hydrogen peroxide and Feizixiao LPPC indicated the most efficient hydroxide radical scavenging ability and DNA damage preventing effect. In conclusion, procyanidins from pericarp of different litchi cultivars acted different antioxidant effects in different chemiluminescence systems.
Key words: LPPC, chemiluminescence method, antioxidant activity in vitro, DNA damage prevention
