Figure 4

Correlation between total phenolic content and (a) DPPH radical scavenging activity of the extracts. Correlation coefficient, r = 0.994 and coefficient of determination, R2 = 0.988. (b) Total antioxidant capacity of the extracts. Correlation coefficient, r = 0.946 and coefficient of determination, R2 = 0.896. (c) Ferric ion reducing antioxidant potential (FRAP) of the extracts. Correlation coefficient, r = 0.974 and coefficient of determination, R2 = 0.949.
