In vitro antioxidant activity of Launaea nudicaulis (Asteraceae)‎ growing in southwest of Algeria

الملخص EN

Antioxidants are vital substances, which possess the ability to protect the body from damages caused by free radical induced oxidative stress.

A variety of free radical scavenging antioxidants is found in a number of dietary sources.

The main objective of this study focused on the screening of antioxidant activity of Launaea nudicaulis (Asteraceae) extracts.

The in vitro antioxidant activity was investigated with DPPH radical scavenging assay.

The quantitative evaluation of DPPH scavenging activity showed that n-BuOH and EtOAc extracts are the most active extracts with a percentage of antiradical activity of 89,62 % and 71,57 % respectively.
