Values are presented as $\bar{x} \pm S E M$ for three replicates. Means with different superscript lower-case alphabets within the same column are significantly different (P < 0.05; one-way ANOVA with Turkey's posthoc test), whereas means with different subscript uppercase alphabets within the same row are significantly different (P < 0.05; independent student's t-test statistic). HRLEOs: H. revolutum leaf essential oils; L-ASA: L-ascorbic acid.
