Antioxidant Activity of the Fresh Juice from Morinda citrifolia
The antioxid ant activity of the fresh juice from Morinda citrifolia,including the polyphenolic content and the antioxidant activity,was studied in order to provide the theory basis for its development.With Vc as the control,spectrophotometry was used to analyse the antioxidant activity of the fresh juice from M.citrifolia.The results showed that the fresh juice from M.citrifolia contained high polyphenolic content(1.934 mg/mL)and had good scavenging activity on DPPH radical,ABTS radical,hydroxyl radical and hydrogen peroxide.Furthermore,it was far more active than Vc in the hydroxyl radical scavenging assay.The fresh juice from M.citrifolia is beneficial to human health because it has good antioxidant activity.
