| Isoflavonoid Phytoalexins of Yam Bean (Pachyrrhizus erosus)  | | | Abstract
| The furanopterocarpan, neodunol, has been isolated as a major phytoalexin from the fungus-inoculated stems o f Pachyrrhizus erosus. N eodunol is accompanied by small quantities o f dem -ethylmedicarpin and a third compound provisionally identified as the prenylated pterocarpan, ho-moedudiol; traces o f a neodunol isomer were also isolated from P. erosus although its precise struc ture could not be determined. The apparently close chemical relationship between Pachyrrhizus and Neorautanenia is discussed in the light o f a recent study which allocates these genera to differ ent sections o f the legum e tribe Phaseoleae. | | |

|  | | | Abstract
| Peroxide oxidation of cajanol ethyl ether afforded the B ring derived product, 2-methoxy-4-ethoxybenzoic acid. For mation of this compound means that the structure of cajanol, a major phytoalexin from Cajanus cajan, must be revised to 5,4'-dihydroxy-7,2'-dimethoxyisoflavanone. | | |

| Isoflavonoid Phytoalexins from Leaflets of Dalbergia sericea  | | | Abstract
| The fungus-inoculated leaflets o f Dalbergia sericea pro duce several isoflavonoid phytoalexins including the known pterocarpans, medicarpin and maackiain, ana the isofla-van, vestitol. A fourth, previously undescribed, phytoalexin has been identified as 7-methoxy-2',4'-dihydroxyisoflavan (neovestitol) by comparison with synthetic material. | | |
