Antioxidant and Free Radical Scavenging Activities of Ervatamia coronaria Stapf. Leaves
The present study was carried out to evaluate the antioxidant and free radical scavenging activity of methanolic extract of Ervatamia coronaria leaves (Apocynaceae) in various systems. DPPH radical, superoxide anion radical, nitric oxide radical and hydroxyl radical scavenging assays were carried out to evaluate the antioxidant potential of the extract. The antioxidant activity of methanolic ex...

متن کاملOxygen free radical and antioxidant defense mechanism in cancer.
The reactive oxygen species (ROS) can damage the nucleic acids. The oxidative modification of the DNA constitutes the fundamental molecular event in carcinogenesis and that is why the interest in the study of the involvement of ROS in that process. On the other hand, oxidative DNA damage-induced mutagenesis is widely hypothesized to be a frequent event in the normal human cell. The enormous evi...
متن کاملAntioxidant and free radical scavenging activity of Spondias pinnata
BACKGROUND Many diseases are associated with oxidative stress caused by free radicals. Current research is directed towards finding naturally-occurring antioxidants of plant origin. The aim of the present study was to evaluate the in vitro antioxidant activities of Spondias pinnata stem bark extract. METHODS A 70% methanol extract of Spondias pinnata stem bark was studied in vitro for total a...
