Correlation between phenolic content and antioxidant activity
Some studies report a strong correlation between phenolic content and antioxidant activity in fruits,
vegetables and grains [14] while other reports do not [12,16]. In this study the antioxidant activity of
the plant extracts correlated well with the total phenolic content. A positive correlation was observed,
whereby the antioxidant activity increased when the total phenolic content increased (Figure 4).
