Antioxidant Activity of Lawsonia inermis Extracts Inhibits Chromium(VI)-Induced Cellular and DNA Toxicity

Figure 5

Relationship between total phenolic content of aqueous and methanolic extracts of L. inermis and (a) ABTS^•+‏ radical scavenging potential. (b) DPPH^• radical scavenging efficiency. (c) Fe³⁺‏ reducing potential. (d) LPI. (e) Cell viability against Cr(VI)-induced toxicity. All parameters show strong and significant positive correlation with total phenolic content (at 𝑃<.05) for both extracts.
