Effect of Luffa echinata on lipid peroxidation and free radical scavengingactivity

The dried alcoholic (50%) extract of the plant Luffa echinata was investiga ted for inhibition of lipid peroxidation, for hydroxyl radical scavenging a ctivity and interaction with 1,1-diphenyl-2-picrylhydrazylstable free radic al (DPPH). It was found that the test extract exhibited a considerable inhibition of l ipid peroxidation and possessed hydroxyl radical scavenging activity. Evalu ation of antiradical scavenging activity showed significant interaction wit h DPPH. These properties could be considered as a useful and exploitable combinatio n for justifying the reported activity.
