1. The extracellular proteins caeruloplasmin and transferrin have important antioxidant properties by virtue of the fact that they inhibit iron-dependent free radical production, and ensuing damage to cells. 2. Albumin is a plasma protein which can loosely bind iron, but the redox activity of this iron has not been fully investigated. 3. The ability of albumin to bind iron and to prevent iron-d...

OBJECTIVES To evaluate the antioxidant potential of porridges (kola kenda) made incorporating herbs. DESIGN Experimental study. Main outcome measures Total phenolic content was estimated by Folin Ciocalteau method (GAEmg/g(FW) and the antioxidant potential by ABTS free radical scavenging activity (TEAC(μg)/100g (FW). RESULTS Total phenolics and antioxidant potentials of porridges ranged fro...

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...

The methanol extracts of leaves of Bauhinia acuminata (MESF) and their different fractions obtained from modified Kupchan partitioning method i.e. methanol, pet ether, carbon tetrachloride, chloroform, and aqueous soluble fractions were subjected to biological screening such as total phenolic content and antioxidant activity screening.The amount of total phenolic content differed in di...

Antioxidant activities of Satureja boissieri extracts were detected by using specific in vitro techniques. Standard antioxidant compounds such as ascorbic acid, BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) were used to compare with the results obtained from ethanol and water extracts of the plant samples. Both extracts presented high antioxidant <span ...
