  • CARCINOGENESIS INHIBITORS
    Publication number: 20020032176
    Abstract: Carcinogenesis inhibitors containing as the active ingredient carotenoids extracted from the pure-line species of paradicsom paprika (species classified as Capsicum annuum L. var. grossum), etc., such as capsanthin, its fatty acid esters, capsorubin diesters, capsanthin 3,6-epoxide, capsorubin and cucurbitaxanthine A-3′ ester. These carcinogenesis inhibitors and paradicsom paprika extracts originate in natural substances and, therefore, make it possible to provide excellent Epstein-Barr virus genome inactivating agents. Thus, they are expected as being useful in preventing carcinogenesis and, based on their effects, applicable in various fields including drugs, cosmetics and health foods.
