ANTIOXIDANT AND FREE RADICAL SCAVENGING ACTIVITY OF SPONDIAS PINNATA PDF

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. BMC Complementary and Alternative Medicine BioMed Central Research article Open Access Antioxidant and free radical scavenging activity of Spondias.
