Coenzyme Q10 is a bioactive component known as a potent antioxidant (Mellons and Tappel, 1996; Lipshutz et al., 2002; Lenaz, 1985a, b). Recent studies have shown that it is able to prevent heart disease as well as slows the degradation due to Parkinsons’ disease. Although naturally produced in the body, the productive mechanism degrades with age. Sources of coenzyme Q10 include algae as well as vegetable oils, such as palm oil (Hamid et al., 1995; Choo et al., 2005; Ng et al., 2005). In view of the benefi ts of coenzyme Q10, it is increasingly taken as a nutritional supplement. The nutraceuticals and cosmetics industries have proliferated with products claimed to contain coenzyme Q10. Being a newly important ingredient in nutraceuticals, cosmetics and personal care products, analyses for coenzyme Q10 are needed to determine its concentration for quality control of the products and production process.
