Curculigo orchioides

Cycloartane saponins seemingly contribute to the immunomodulatory properties of Astragalus, in fact, curculigosaponin G from Curculigo orchioides was reported to significantly promote the proliferation of spleen lymphocytes in mice compared to controls, without a marked influence on antibody formation [167]. 

The bulbs of Hippeastrum ananuca have been shown to contain lycorine, homolycorine, and the rare alkaloid maritidine (1). Lycorine has also been isolated for the first time from the rhizomes of Curculigo orchioides and from the leaves of Ungernia tadshicorum maritidine is a constituent of Zephyranthes robusta and of Z. sulphurea and an X-ray crystallographic study of the alkaloid has been carried out. Two new alkaloids, hippeastidine (2) and 17-epi-homolycorine (3), were obtained from Hippeastrum ananuca and their structures were established by X-ray analysis.

Taxonomy Cycloartane Glycosides Curculigo orchioides Gaerth. (Hypoxidaceae) [1]. 

Curculigosaponin G (33), a new cycloartane type triterpene saponin from the rhizomes of Curculigo orchioides was shown to significantly promote proliferation of spleen lymphocytes in mice (p < 0.01) but no marked influence on antibody formation was seen (p > 0.05) [65].
