Effect of differentsSolvents extraction on antioxidant activity of Ipomoea aquatica

Antioxidants play an important role in inhibiting and scavenging free radicals, thus providing protection to human against infections and degenerative diseases. Current researchers are now directed towards natural antioxidants of plants origin due to safe therapeutics. Ipomoea aquatica Forsk is a gr...
