Bobgunnia madagascariensis ( Bambara: samagara), also called the snake bean plant, [2] is a species of legume in the family Fabaceae. Sometimes sold as "Pau Rosa", along with Bobgunnia fistuloides.
Bobgunnia madagascariensis is a small deciduous tree, 3–4 m tall. The plant has large pods that turn dark when ripe. [2]
The larvae of Abantis zambesiaca feed on B. madagascariensis.
Bobgunnia madagascarensis is toxic. [3]
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]
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, swartziasaponin A and B and swartziagenin, a mixture of oleanolic and O-acetyloleanolic acid. [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 (−)- maackiain, (−)- medicarpin, gypsogenin 3-O-rhamnosylglucuronide, (−)- homopterocarpin, pterocarpin, 4-methoxymedicarpin, 4-methoxymaackiain, 4-methoxyhomopterocarpin, 4-methoxypterocarpin, anhydrovariabilin and coumestrol dimethyl ether. [9]
