Objective: To study the Correlation of the contents of total phenols and total flavonoids and antioxidant activities of five Callicarpa species. Method: The contents of total phenols
total flavonoids of five Callicarpa species were detected with Uv-Visible spectrophotometer. Subsequently
the antioxidant activities of five Callicarpa species were determined by seven antioxidant methods
including·O2- scavenging
DPPH·scavenging
ABTS+·scavenging
·OH scavenging
Cu2+-chelating
and Fe3+ reducing assays
anti-lipidperoxidation. Result: The contents of total phenols
total flavonoids of five Callicarpa species were significantly different with each other and Callicarpa nudiflora Hook. et Arn possessed the highest contents. There were various kinds of relationship about antioxidant activities of five Callicarpa species from seven methods. The results of correlation analysis indicated that there was a positive correlation between the contents of total phenols and total flavonoids and antioxidant activities apart from anti-lipidperoxidation activity. Conclusion: Five Callicarpa species were rich in phenols and flavonoids
had excellent antioxidant activities
so they would be developed as new natural antioxidants.
