Table 4 Correlation between phytochemical content, antioxidant, anti-inflammatory and antiproliferative activity of active extracts

From: Croton gratissimus leaf extracts inhibit cancer cell growth by inducing caspase 3/7 activation with additional anti-inflammatory and antioxidant activities

  1. Correlation coefficients were determined by plotting a linear curve with IC50 values of extracts obtained for each cancer cell on the y-axis against the corresponding phytochemical content or IC50 values of the antioxidant power (DPPH, ABTS) and anti-inflammatory activity (NO, 15-LOX) on the x-axis. NO: nitric oxide, 15-LOX: 15-lipoxygenase. TPC: total phenolic content, TFC: total flavonoid content, DPPH: 2,2-diphenyl-1-picrylhydrazyl radical, ABTS: 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical
