  1. Each value in the table is represented as mean ± SD (n = 3). Means within each column with different letters (a-e) differ significantly (p < 0.05) according to ANOVA with Newman-keuls multiple comparison test when compared with standard. For FRAP compared total phenolic and total flavonoid content where **P < 0.01, *P < 0.05, ns P > 0.05 according to ANOVA with Bonferroni posttests
