Regression analysis of total phenolic content of P. mariana extracts with respect to antioxidant activity. Total phenolic content is measured in terms of quercetin equivalents and antioxidant activity is calculated with respect to the ascorbic acid standard curve. The trend shows that as phenolic content increases the amount of plant extract (EC50 in ppm) necessary to reach the IC50 of ascorbic acid decreases and therefore, antioxidant activity increases with increasing phenolic content (r2 = 0.63, p ≤ 0.05, n = 14). The data passed a normality test in order to ensure that it follows a normal distribution
