Significance of DPPH radical scavenging
DPPH radical scavenging is a widely recognized method for assessing the antioxidant capacity of various substances. It measures the ability of antioxidants to neutralize the stable DPPH radical, which is indicative of their effectiveness in combating oxidative stress. This method is utilized in various studies to evaluate the antioxidant activity of different extracts and compounds, such as Cissus quadrangularis and Thymelaea microphylla, by determining how well they can scavenge DPPH free radicals.
