Abstract

|
|
|
A high dietary intake of polyphenols has been associated with a decreased risk of cardiovascular disease and cancer, attributed in part to their antioxidant activity and pro-apoptotic effects. Aquamin is a multi-mineral algal extract that enhances bone mineralization, relieves osteoarthritis, and aids digestion; however, Aquamin has not demonstrated antioxidant activity. In the present study, Aquamin was supplemented with 8% Enzogenol, a pine bark extract with a high phenolic content, and 2% Sunphenon, a green tea extract that also has a high phenolic content to produce a mixed product (A:E:S). The antioxidant activity of A:E:S was compared with that of its constituent compounds and also with catechin and epigallocatechin by measuring total phenol content, ferric-reducing antioxidant potential, and 2,2-diphenyl-2-picrylhydrazyl hydrate. The cytotoxic and apoptotic effects of the compounds were also measured in the U937, human monocytic blood cell line. A:E:S demonstrated an antioxidant activity that was equal to that of the compounds used in its preparation. Aquamin was not cytotoxic in the U937 cell line; however, A:E:S was cytotoxic and the primary mechanism of cell death was apoptosis. The biological effects of Aquamin were enhanced by supplementation with Enzogenol and Sunphenon to include antioxidant effects and the ability to induce apoptosis in U937 cells.
