	Title	Flavonoid and Isoflavonoid Compounds from Leaves of Sainfoin
	Abstract	Phytoalexins The 5-deoxyisoflavones, afrormosin and formononetin have been isolated from healthy leaves of Onobrychis viciifolia. In addition to these compounds, several other flavonoid (iso-liquiritigenin; liquiritigenin; garbanzol) and isoflavonoid (medicarpin; vestitol) derivatives including the new iso-flavanone, vestitone (7,2'-dihydroxy-4'-methoxyisoflavanone), are present in leaves inoculated with the fungus Helmintho-sporium carbonum.

	Title	of the Genus Caragana
	Abstract	The fungus-inoculated leaflets of 39 Caragana species have been found to variously produce five isoflavonoid phytoalexins including the known pterocarpan derivatives, medicarpin, maackiain, variabilin and pisatin. Small quan tities of a previously undescribed C-methylated pterocarpan were obtained from leaflets of C. acanthophylla.

	Title	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.

These include 12 known isoflavonoids: genistein, 2'-hydroxygenistein, 2'-hydroxydaidzein, kievitone, dalbergioidin, cyclokievitone, 5-deoxykievitone, 2'-hydroxydihydrodaidzein, isoferreirin, aureol, glycinol and demethylvestitol.

	Title	Isoneorautenol and Other Pterocarpan Phytoalexins from Calopogonium mucunoides
	Abstract	Following inoculation with the fungus H elm inthosporium carbonum , excised leaflets o f the tropical papilionate legum e C alopogonium m ucunoides have been found to produce isoneorautenol, a new dim ethylpyrano-substituted isoflavonoid (pterocarpan) phytoalexin. This com pound accumulates together with dem ethylm edicarpin, neodu nol, tuberosin, sophorap-terocarpan A , and a sixth highly antifungal isoflavonoid (calopocarpin) characterised as 3,9-dihydroxy-2-(3,3-dim ethylallyl)pterocarpan. Chrom atographic and spectroscopic exam ination of 'hom oedudiol' (a pterocarpan from N eorautanenia edulis roots previously considered to possess the structure now assigned to calopocarpin) has shown that in reality this substance is identical with sophorapterocarpan A . The system atic relationship o f C alopogonium to other genera within the legum e tribe P haseoleae is briefly discussed.

	Title	Effects of Culture Conditions on Isoflavonoid Levels of Transformed and Non-Transformed Cultures of Lupinus -a Comparison of Suspension and Hairy Root Cultures
	Abstract	Some highly productive suspension and hairy root cultures were found among several trans formed cultures o f Lupinus polyphyllus and L. hartwegii. A transformed suspension culture Lupo 30150 and a root culture Luha 15834 containing the highest specific isoflavone glucoside content were characterized and compared with normal phytohormone-dependent lines with respect to product stability as well as to their responsiveness to external triggers, e.g. response to changes in the medium. While phytohorm one-dependent suspension cultures lost their ini tial ability to form increased levels o f isoflavonoids on phytohormone-free medium, the trans formed phytohorm one-independent suspension Lupo 30150 remained a highly productive line, despite the fact that its specific levels decreased to 60% o f the initial values during several years in liquid medium. Highest stability o f product patterns and levels were noted for the transformed root culture. Phytohorm ones had little effect on growth and isoflavonoid levels in suspension cultures, while they reduced both strongly in root cultures. In the presence o f 2,4-D the root culture changed into an aggregated low producing suspension culture from which the root state was recovered on phytohorm one-free medium. As long as the root state was main tained, isoflavonoid levels could not be distinctly improved by media variation while specific isoflavonoid levels o f suspensions were increased by stress factors such as phosphate depletion. When suspensions were transferred to fresh medium phenylalanine ammonia-lyase was greatly induced within 24 h, while the activity remained nearly unchanged in root cultures.

	Title	Fungitoxic Isoflavones from Lupinus albus and other Lupinus Species
	Abstract	The constitutive isoflavones genistein, 2'-hydroxygenistein, wighteone and luteone have been isolated in varying amounts from methanolic leaf washings of eight species belonging to the legume genus Lupinus. These four compounds likewise occur in the flower buds, stems, roots and im mature pods o f L. albus, and in stems and roots o f L. angustifolius and L. mutabilis. A m inor isoflavone present in L. albus and L. luteus leaf washings has been identified by chemical and spectroscopic procedures as 5,7,4'-trihydroxy-3-methoxy-6-(3,3-dimethylallyl)isoflavone (lupiso-flavone). Apart from genistein, 2'-hydroxygenistein, wighteone and luteone, the roots of L. albus also contain alpinumisoflavone, licoisoflavone B and 6,3'-di-(3,3-dimethylallyl)genistein (lupalbi-genin).
