 Abstract    In response to fungal inoculation the leaves of Trifolium arvense accumulate the known isoflavonoid phytoalexins, medicarpin, maackiain, sativan, vestitol, and isovestitol. A previously undescribed isoflavan derivative (arvensan; 7,2'-dimethoxy-4'-hydroxyisoflavan) is also produced by this species. The identification and synthesis of arvensan is described.

 Title    Induced Isoflavonoids of Erythrina sandwicensis  
 Abstract    Two new phytoalexins isolated from the fungus-inoculated leaflets of Erythrina sandwicensis have been identified as (—)-6aS; 11 aS-3,6 a,9-trihydroxy-10-isopentenylpterocarpan (sandwicar-pin) and (—)-6a/?; 11 a^-3-hydroxy-9-methoxy-10-isopentenylpterocaipan (sandwicensin). These compounds co-occur with several known pterocarpan (demethylmedicarpin, 3,6a,9-trihydroxy-pterocarpan, phaseollidin and cristacarpin) and isoflavan (demethylvestitol and isovestitol) deriva­ tives. The preparation and spectral (UV, MS) characteristics of 3-methoxy-9-hydroxy-10-isopen-tenylpterocarpan are also described.

 Title    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.
