Chamaelirium luteum is a native lily of the eastern US. It is considered a threatened species because of a loss of habitat and effects of collection from the wild for herbal use. Cultivation is considered possible, but has not yet become commercially important. The root is collected in autumn. C. luteum is a dioecious species (ie, the male and female flowers are borne on separate plants). The plant has been confused with the lilies Helonias bullata and Aletris farinosa (true unicorn root), because of several shared common names.

It has also been used for appetite stimulation and as a diuretic, vermifuge, emetic, and insecticide.

Chemistry

The root contains = 10% of a saponin, chamaelirin (C36H62018), but neither its structure nor composition have been fully elucidated. Diosgenin was isolated from a hydrolyzate of the root extract, indicating that some components of the saponin may be based on this genin? The fatty acids oleic, linoleic, and stearic acid were isolated from the root.
