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 ( ...

Sophora Flavescens
''Sophora flavescens'', the shrubby sophora, is a species of plant in the genus ''Sophora'' of the family Fabaceae. This genus contains about 52 species, nineteen varieties, and seven forms that are widely distributed in Asia, Oceania, and the Pacific islands. About fifteen of these species have a long history of use in traditional Chinese medicines. Growth and cultivation ''Sophora flavescens'' is an evergreen slow growing shrub growing to by . It is hardy to and to US zone 6. The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires moist soil. Like many other species in the family Fabaceae, this species can fix nitrogen. Chemistry Chemical compounds isolated from ''S. flavescens'' include: * Matrine and matrine oxide, quinolizidine alkaloids found in the roots * Kushenin, a pterocarpan and isoflavonoid * Sophoraflavanone ...
