Barbigerone is one of a few pyranoisoflavones among several groups of isoflavones. It was first isolated from the seed of a leguminous plant Tephrosia barbigera; hence the name "barbigerone".[1] Members of the genus Millettia are now known to be rich in barbigerone, including M. dielsiena,[2] M. ferruginea,[3] M. usaramensis,[4] and M. pachycarpa.[5] It has also been isolated from the medicinal plant Sarcolobus globosus.[6] Barbigerone from S. globosus is validated to have significant antioxidant property.[7] Barbigerone exhibits profound antiplasmodial activity against the malarial parasite Plasmodium falciparum.[8] It is also demonstrated that it has anti-cancer potential as it causes apoptosis of murine lung-cancer cells.[9]
