 Title    Bi-and Triflavonoids of Representative Moss Species from Six Different Families  
 Abstract    The identity of the bi-and triflavonoids of six moss species from six different fam ilies has been proved by N M R . The individual flavonoids are: 3 ', 3"'-binaringenin, 5 ', 3"'-dihydroxy-am entoflavone, 5 ', 3"'-dihydroxyrobustaflavone, cam pylopusaurone, aulacom nium triluteolin, philonotisflavone, dicranolom in, and 2, 3-dihydrodicranolom in.

 Title    A New Class of Biflavonoids: 2'-Hydroxy genistein Dimers from the Roots of White Lupin  
 Abstract    b C REST of Japan Science and Technology Corporation. Fax: + 8 1 -1 1 -7 0 6 -4 1 8 2 . E-mail: tahara@abs.agr.hokudai.ac.jp Two novel isoflavonoid dimers presumably originating from 2'-hydroxygenistein, 5,7,4'-trihydroxycoumaranochroman-4-one-(3-*5'")-5",7",2'",4'"-tetrahydroxyisoflav-one (1, lupinal-bisone A) and 5,7,4'-trihydroxycoumaranochro-man-4-one-(3—>-6")-5",7",2"',4"'-tetrahydroxy-isoflavone (2, lupinalbisone B) were isolated from the roots of Lupinus albus L., and their structures involving relative stereochemistry were elucidated by spectroscopic methods. U sing horse radish peroxidase and 2'-hydroxygenistein (3) as the substrate revealed the for­ mation o f these dimers together with 5,7,4'-trihydroxycoumaronochromone (4, lupinalbin A). Dimerization of 3 caused a remarkable increase of antifungal activity.

 Title    External Accumulation of Biflavonoids on Gymnosperm Leaves  
 Abstract    Biflavonoids are well known to occur in many Gymnospermae. Here we report on their occurrence in epicuticular material of a num ber of species. Several compounds are charac­ terized by detailed NMR studies and FAB-MS. They are identified as amentoflavone, bilobe-tin, podocarpus-flavone A, sciadopitysin, dihydrosciadopitysin and cupressuflavone.
