	Title	Sparticarpin: A Pterocarpan Phytoalexin from Spartium junceum Reading RG 6 2 AS
	Abstract	A new phytoalexin isolated from the fungus-inoculated leaflets o f Spartium junceum (Spanish broom) has been identified as (—)-6 aR; 11 a/?-2,3-dimethoxy-9-hydroxypterocarpan (sparticar pin). The total synthesis o f sparticarpin 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	Phytoalexins from Dolichos biflorus
	Abstract	, 2'-hydroxygenistein, dalbergioidin, kievitone and phaseollidin have been found to accumulate in leaves and stems of Dolichos biflorus (horsegram) following inoculation with the non-pathogens Pseudomonas pisi and Phytophthora megasperma f. sp. glycinea, respectively. They are accompanied by isoferreirin (5,7,4'-trihydroxy-2'-methoxyisoflavanone), a compound not previously reported as a natural product. Coumestrol and psoralidin occur constitutively in Dolichos leaves and stems.
