Bobgunnia madagascariensis (), also called the snake bean plant, is a species of legume in the family Fabaceae. Sometimes sold as "Pau Rosa", along with Bobgunnia fistuloides.
Description.
"Bobgunnia madagascariensis" is a small deciduous tree, 3–4 m tall. The plant has large pods that turn dark when ripe.
Ecology.
The larvae of "Abantis zambesiaca" feed on "B. madagascariensis".
Toxicity.
"Bobgunnia madagascarensis" is toxic.
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. Seeds, fruits and stem bark are also used in fishing by poisoning in Africa.
Chemistry.
The methanolic extract of the fruit of "B. madagascariensis" contains a saponin tetraglycoside.
The root bark of "B. madagascariensis" contains quinone methide diterpenes.
The seed pod contains two acidic saponins, swartziasaponin A and B and swartziagenin, a mixture of oleanolic and O-acetyloleanolic acid. The pod methanolic extract yields highly glycosylated flavonoids (glycosides of kaempferol and quercetin).
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.
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.
