Abstract
|
|
|
|
Screenings of potential antioxidant activities of Crataegus pinnatifida BUNGE Major. fruits extracted 80% methanol were performed using four antioxidant assays. Significant differences were observed both in total phenolic contents (TPC) and total flavonoid contents (TFC), DPPH radical scavenging activity, nitric oxide scavenging activity, ABTS radical scavenging assay, and reducing power assay. The total polyphenol content and total flavonoid content in the extract were measured to be 224.4 ± 0.52 mg GAE/100 g and 12 ± 0.25mg QE/100 g, respectively. When the tested concentration was 500 ug/mL, DPPH and ABTS radical-scavenging activities of methanolic extracts were 84.15% and 88.8%, respectively. The reducing power and nitric oxide scavenging activity were increased at the manner of dose-dependently. These results suggest that methanolic extracts of Crataegus pinnatifida Bge. fruits possess excellent radical scavenging activities and may serve as a potential source of natural antioxidant.
