 Title    Sesquiterpene Lactones from Centaurea achaia, a Greek Endemic Species: Antifungal Activity  
 Abstract    The aerial parts of Centaurea achaia afforded, in addition to several known sesquiterpene lactones and sesquiterpene hydroxyesters, a new germacranolide and a new elemanolide. Their structures were determined as the 8a-0-(4,5-dihydroxy-tigloyloxy) esters of saloniteno-lide and of 11,13-dihydromelitensin, respectively. The in vitro antifungal activity of most compounds was tested against nine fungal species using the micro-dilution method. All the tested compounds showed strong antifungal activity.

 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).
