Osmanthus fragrans Flower Source & Identity
The botanical entity is Osmanthus fragrans Lour., the sweet osmanthus or tea olive of the Oleaceae, an evergreen shrub or small tree whose leathery leaves carry autumn clusters of tiny white, yellow or orange flowers. The part used is the flower. Leaf, fruit and bark are not part of this Osmanthus fragrans extract.
Cultivar groups differ in flower color, from silvery white to deep orange, and the carotenoid content follows the color. Holly osmanthus, Osmanthus heterophyllus, is another species. The flower holds phenylethanoid glycosides such as verbascoside, flavonoid glycosides and carotenoids, named here only as constituent families, and a delicate fragrant oil.
