 Title    Biosynthesis of Isoflavonoid Phytoalexins: Incorporation of Sodium |1,2-13C2] Acetate into Phaseollin and Kievitone  
 Abstract    13C-NMR analysis of the isoflavonoid phytoalexins phaseollin and kievitone produced by feeding sodium [l,2-13C2]acetate to wounded bean (Phaseolus vulgaris) cotyledons has demon­ strated the incorporation of intact acetate units into the aromatic A rings. Phaseollin shows a specific folding of the polyketide chain, whereas kievitone exhibits a randomisation of label in accordance with the intermediacy of a 2',4',6'-trihydroxylated chalcone during its formation. In neither case was sufficient label incorporated into analysis.

 Title    Aureol and Phaseol, Two New Coumestans from Phaseolus aureus Roxb  
 Abstract    Two new coumestans, aureol and phaseol, isolated from Phaseolus aureus have been charac­ terized as 1,3.9-trihydroxycoumestan and 3,9-dihydroxy-4-(y,y-dim ethylallyl)-coum estan, respectively.
