Swartzia Madagascariensis
''Bobgunnia madagascariensis'' ( bm, samagara), also called the snake bean plant, 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. 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 0-acetyloleanolic acid. T ...

Pterocarpan
Pterocarpans are derivatives of isoflavonoids found in the family Fabaceae. It is a group of compounds which can be described as benzo-pyrano-furano-benzenes (i.e. 6''H''- enzofuro,2-chromene skeleton) which can be formed by coupling of the B ring to the 4-one position. 2'-hydroxyisoflavone reductase is the enzyme responsible for the conversion in ''Cicer arietinum'' and glyceollin synthase for the production of glyceollins, phytoalexins in soybean. Known compounds * Bitucarpin A and B, isolated from the aerial parts of Mediterranean plants '' Bituminaria morisiana'' and '' Bituminaria bituminosa'' * Erybraedin A and B, isolated from the stems of '' Erythrina subumbrans'' and C, isolated from the leaves of '' Bituminaria morisiana'' * Erythrabyssin II, erystagallin A, erythrabissin-1, and erycristagallin isolated from the stems of '' Erythrina subumbrans'' * Glycinol, glyceollidin I and II, glyceollins ( glyceollin I, II, III and IV), found in the soybean ( ...

Baphia Nitida
''Baphia nitida'', also known as camwood, barwood, and African sandalwood (although not a true sandalwood), is a shrubby, leguminous, hard-wooded tree from central west Africa. It is a small understorey, evergreen tree, often planted in villages, and known as ''osun'' in Yoruba. The wood is of a very fine colour, and is used in woodturning for making knife handles and similar articles. The tree's bark and heartwood are commonly used to make a brilliant but non-permanent red dye, which is soluble in alkali.

Pterocarpus
''Pterocarpus'' is a pantropical genus of trees in the family Fabaceae. It belongs to the subfamily Faboideae, and was recently assigned to the informal monophyletic ''Pterocarpus'' clade within the Dalbergieae. Most species of ''Pterocarpus'' yield valuable timber traded as padauk (or padouk); other common names are mukwa or narra. '' P. santalinus'' also yields the most precious red sandalwood in China known as Zitan. The wood from the narra tree ('' P. indicus'') and the Burmese padauk tree ('' P. macrocarpus'') is marketed as amboyna when it has grown in the burl form. The scientific name is Latinized Ancient Greek and means "wing fruit", referring to the unusual shape of the seed pods in this genus. Uses Padauk wood is obtained from several species of ''Pterocarpus''. All padauks are of African or Asian origin. Padauks are valued for their toughness, stability in use, and decorativeness, most having a reddish wood. Most Pterocarpus' woods contain either water- or al ...

Sophora Angustifolia
''Sophora'' is a genus of about 45 species of small trees and shrubs in the pea family Fabaceae. The species have a pantropical distribution. The generic name is derived from ''sophera'', an Arabic name for a pea-flowered tree. The genus formerly had a broader interpretation including many other species now treated in other genera, notably ''Styphnolobium'' (pagoda tree genus), which differs in lacking nitrogen fixing bacteria ( rhizobia) on the roots, and ''Dermatophyllum'' (the mescalbeans). ''Styphnolobium'' has galactomannans as seed polysaccharide reserve, in contrast ''Sophora'' contains arabinogalactans, and ''Dermatophyllum'' amylose. The New Zealand ''Sophora'' species are known as kowhai. The seeds of species such as ''Sophora affinis'' and ''Sophora chrysophylla'' are reported to be poisonous. Fossil record One ''Sophora'' fossil seed pod from the middle Eocene epoch has been described from the Miller clay pit in Henry County, Tennessee, United States. Species '' ...
