 Title    Polyphenolic Compounds from Plantago lagopus L  
 Abstract    In the present study we report the isolation of a phenylpropanoid glucoside, plantamajo-side, together with rosmarinic acid, chlorogenic acid and luteolin-7-O-monoglucoside. This is the first report of these compounds from Plantago lagopus.

 Title    Major Flavanones from Lonchocarpus guatamalensis  
 Abstract    The flavanones 25-lupinifolin and 2/?:3/?-lupinifolinol have been isolated as major components from a methanolic extract of Lonchocarpus guatamalensis root bark. These known compounds occur together with a minor flavanone (2/?:3/?-3-0-methyl-lupinifolinol) not previously recog-nized as a natural product.

 Title    Accumulation of Phenolic Compounds in Leaves of Tomato Plants after Infection with Clavibacter michiganense subsp. michiganense Strains Differing in Virulence  
 Abstract    Infection experiments using tom ato (Lycopersicon esculentum cv. M oneymaker) plants and three strains o f Clavibacter michiganense subsp. michiganense were conducted. The bacterial isolates differed in plasmid status, virulence (measured as wilting index and as reduction o f plant biomass) and the ability to colonize the plants. Differences in the expression o f exopoly­ saccharides and the exoenzymes endocellulase, polygalacturonase, and xylanase, respectively, were not found with the bacterial isolates. As infection-induced responses o f the plants time-depending increases in soluble phenolic material, including chlorogenic acid and rutin, in the steroid alkaloid tom atine and in cell wall-bound cinnamic acids were found. In the latter frac­ tion / 7-coum aric, ferulic and especially caffeic acid were the main constituents. All plant responses were preferentially expressed in the compatible interaction. Sesquiterpenoid phyto­ alexins were not found in the infected plant tissues. The relation between bacterial pathogen­ icity and plant responses is discussed.

 Title    Phenolic Compounds in Needles of Norway Spruce Trees in Relation to Novel Forest Decline. II. Studies on Trees from Two Sites in Middle Western Germany  
 Abstract    The content of several phenolic compounds in needles of 20-to 30-year-old Norway spruce trees (Picea abies) was measured using HPLC. The results of two forestry sites in middle western Germany are reported in this paper. They are part of a research programme on novel forest decline which was carried out in various regions of Germany. Distinct amounts of picein, catechin, piceatannol glucoside, and other phenolic compounds were detected in the studied spruce needles. Additionally, their contents changed in relation to damage. Some compounds, especially catechin, showed increased levels in the needles of the damaged trees compared to the undamaged ones. Here, the values for the undamaged trees of the different sites were similar. Concerning the changes in picein contents, however, there was a great difference between the sites. p-Hydroxyacetophenone was detected in very low amounts only and did not correlate with damage. These results are compared with earlier findings from another site that shows severe dam­ age. The role of phenolic compounds as indicators of tree damage is discussed.

 Title    Phenolic Compounds as a Tool of Bioindication for Novel Forest Decline at Numerous Spruce Tree Sites in Germany  
 Abstract    Within a project that applied biochemical criteria to the diagnosis of damage to Norway spruce, 43 sites in western and eastern Germany showing only moderate tree damage were screened for the amounts of methanol soluble phenolic compounds in spruce needles. The concentrations of most of the main compounds -especially catechin -positively correlated with needle loss and the altitude of the site. It was also found that it is necessary to differenti­ ate between trees younger and older than 60 years of age. The correlations between the increase of the phenolic compounds studied and the needle loss or the damage class are stronger in the younger trees, possibly implicating differences in metabolic state or distur­ bances in protectective mechanisms in the older trees.

 Title    Evalution of Phenolic Compounds in Brazilian Propolis from Different Geographic Regions  
 Abstract    Chem om etrics has been shown quite efficient to uncover relationships between chemical composition of a sample and its geographical origin. Forty propolis samples originated from the the South and South E ast of Brazil were analyzed by H P L C and 18 compounds of interest were studied which included: caffeic, p-coum aric and ferulic acids, and some of their derivatives, pinobanksin, a derivative of kaempferol and five phenolic compounds (assigned as 3-prenyl-4-hydroxycinnamic acid (P H C A); 2,2-dim ethyl-6-carboxyethnyl-2H -l-benzopy-ran (D C B E); 3,5-diprenyl-4-hydroxycinnamic acid (D H C A); compound E (still unknown) and 6-propenoic-2,2-dim ethyl-8-prenyl-2H-l-benzopyran acid (D P B). Principal Component Analysis (P C A) indicated three different groups of propolis samples, having the same typical chrom atogram , evaluated by H PLC . Samples from the South E ast group were rich in deriva­ tives of kaempferol. Samples from the South group I had a high content of D P B compound, but a low concentration of kaempferol derivatives and of D C B E N compound. Samples from the South group II were characterized by a high concentration of D C B E N , D H C A , p-coum -aric and D P B compounds. Therefore, the identification of new compounds in Brazilian prop­ olis can give useful information about the plant sources of a given geographic region.

 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).
