Bobgunnia madagascariensis (Bambara: samagara), also called the snake bean plant,[2] is a species of legume in the family Fabaceae.
Description[]
Bobgunnia madagascariensis is a small deciduous tree, 3–4 m tall. The plant has large pods that turn dark when ripe.[2]
Ecology[]
The larvae of Abantis zambesiaca feed on B. madagascariensis.
Toxicity[]
Bobgunnia madagascarensis is toxic.[3]
Applications[]
Poison composed of the roasted seeds of Bobgunnia madagascariensis and innards of the beetle Diamphidia nigroornata is applied to the arrows of the Bushmen.[citation needed] Seeds, fruits and stem bark are also used in fishing by poisoning in Africa.[4]
Chemistry[]
The methanolic extract of the fruit of B. madagascariensis contains a saponin tetraglycoside.[5]
The root bark of B. madagascariensis contains quinone methide diterpenes.[6]
The seed pod contains two acidic saponins, and and swartziagenin, a mixture of oleanolic and .[7] The pod methanolic extract yields highly glycosylated flavonoids (glycosides of kaempferol and quercetin).[8]
The crude chloroform and methanol extracts of the stem bark of the plant show strong feeding deterrent activity against stored-product insect pest of maize Tribolium castaneum with the two compounds, methyl paraben and lupeol, being identified in these extracts.[citation needed]
Other compounds in B. madagascariensis are (−)-, (−)-medicarpin, , (−)-, pterocarpin, , , , , and .[9]
