The distribution and content of ubiquinone in foods.

Abstract

We measured ubiquinone (UQ)-9 and UQ-10 content in various foods using high performance liquid chromatography. UQ-9 was detected in cereals, some vegetables and their products. Corn oil and wheat germ had large amounts of UQ-9 in particular. UQ-10 was detected in meats, fishes, pulses, nuts, dairy products and various vegetables. Migratory fishes, rapeseed oil and soybean oil had considerably large amounts of UQ-10.
