Figure 2.

Anticancer and antioxidant activities of F1, F2, and F3 fractions. F1 (a), F2 (b), and F3 (c) fractions, as shown in Figure 1 b, were diluted in a series of concentrations, and their inhibition on the proliferation of human lung adenocarcinoma cells (A549) was determined; (d) Total phenolic contents expressed as gallic acid equivalents in the fractions; (e) Flavonoid contents expressed as rutin equivalents in the fraction; (f) Reducing powers expressed as FeSO₄ equivalents of the fractions; (g) IC50 values of the fractions for DPPH radical scavenging activity with vitamin C (Vit C) as the reference. The values are the means of three measurements. Error bars indicate the SEM (Standard Error of Mean) of the values.
