Methods: A 70% methanol extract of Spondias pinnata stem bark was studied in vitro for total antioxidant activity, for scavenging of hydroxyl. BACKGROUND: Many diseases are associated with oxidative stress caused by free radicals. Current research is directed towards finding naturally-occurring.

Oxidative stress is initiated by free radicals, [3]. The upper portion of the solution 1 Hydroxyl radical scavenging ml was mixed with 1 ml distilled water, and 0.

Both these classes of compounds have good antioxidant potential and their effects on human nutrition and health are considerable.
