Abstract

La présente invention concerne des extraits dastéracées qui contiennent des niveaux réduits de dérivés de thiophène phototoxique. On décrit de nouveaux procédés qui peuvent se traduire par une réduction de 50 à 100 fois ou plus des niveaux de thiophènes phototoxiques dans des procédés commercialement attrayants. Les extraits de plantes dastéracées comprenant des xanthophylles avec des niveaux réduits de dérivés de thiophène peuvent être utilisés dans des applications qui comprennent des suppléments nutritionnels et des produits cosmétiques.
