Chemical constituents
A variety of chemical compounds have been identified in F. elastica. Unprocessed F. elastica powder is distinctly blue due to its anthocyanin content.{{citation needed|date=March 2015}} The steroidal alkaloid conessine, which is found in F. elastica, has anti-bacterial properties in vitro.Bogne Kamga P, Penlap Beng V, Lontsi D, et al.

Bioactivities
Crude extracts of F. elastica inhibit growth of many molds, including Aspergillus, Penicillium, and Candida, as well as the fungi that cause ringworm.Adekunle AA, Ikumapayi AM.
