 The petals and pollen of "Calendula officinalis" contain triterpenoid esters and the carotenoids flavoxanthin and auroxanthin (antioxidants and the source of the yellow-orange coloration).The leaves and stems contain other carotenoids, mostly lutein (80%), zeaxanthin (5%), and beta-carotene.Plant extracts are also widely used by cosmetics, presumably due to presence of compounds such as saponins, resins, and essential oils.
