Rotenoid

Rotenoids are naturally occurring substances containing a cis-fused tetrahydrochromeno[3,4-b]chromene nucleus.

[4] Deguelin, dehydrodeguelin, rotenol, rotenone, tephrosin and sumatrol can be found in Indigofera tinctoria.

[6] Amorphol, a rotenoid bioside, can be isolated from plants of the genus Amorpha.

[7] Deguelin, rotenone, elliptone and α-toxicarol can be found in the seeds of Lonchocarpus salvadorensis.

[12] In 2015, a new rotenoid called crocetenone was extracted from the rhizome of Iris crocea.
