Aluminum Oxide Column

Lingcod liver oil unsaponifiable material was separated into three main fractions by means of an aluminum oxide column. Major components of the three fractions were vitamin A, cholesterol, and glyceryl ethers, respectively. These fractions were given as dietary supplements to cholesterol-fed chicks and the effect of the supplements on the hypercholesterolemia induced by the cholesterol feeding was investigated. The fraction containing vitamin A prevented the hypercholesterolemia. Crystalline vitamin A acetate produced a similar effect when it was added as a dietary supplement. It was concluded that vitamin A was probably the hypocholesterolemic agent in lingcod liver oil although other compounds in the oil may also exert some influence on the control of the serum cholesterol concentrations in the chicks.

Cod Liver Oil

We very much regret that we were wrong in suggesting cod-liver oil BP as an acceptable equivalent to Maxepa. The dose of 20ml per day, which would be needed to provide a similar amount of marine triglycerides as 10ml of Maxepa, contains excessive amounts of vitamins A and D. Other, non-BP preparations of cod-liver oil contain less vitamin A and D and could be used as an alternative to Maxepa, but details of their composition and its constancy are not generally available except for Seven Seas cod-liver oil, which is therefore the best choice among them.

Marine Oils

Certain fish liver oils, when present in the diet, prevented hypercholesterolemia in chicks produced by cholesterol feeding. The hypocholesterolemic activity of the oils was proportional to the amount incorporated into the diet. Vitamin A-enriched corn oil produced similar results but corn oil itself was without effect. It was concluded that vitamin A was responsible for 73 to 85% of the activity of the fish liver oil. The cause of the additional activity of the marine oils is at present unknown.
