Significance of DPPH scavenging activity
DPPH scavenging activity is an essential method to assess the antioxidant potential of various extracts. It measures the ability of antioxidants to donate electrons or hydrogen to the DPPH radical, leading to a reduction in its stable form, indicated by a color change from purple to yellow. This assay evaluates the capacity of compounds to neutralize free radicals, providing insight into their effectiveness against oxidative stress. The consistent use of the DPPH method highlights its importance in evaluating antioxidant activities in plant extracts.

The concept of DPPH scavenging activity in scientific sources
DPPH scavenging activity is a method that evaluates how effectively antioxidants neutralize DPPH radicals, reflecting their potential to inhibit oxidative stress by reducing the absorbance of a DPPH solution, demonstrating their capacity to combat free radicals.
