 Title    Some Lichen Products Have Antimicrobial Activity  
 Abstract    Antimicrobial activity in some lichens from south Spain has been studied. Some lichenical substances are also identified. The structures of all compounds were elucidated by physical, spectral and chemical methods. A very high activity against Gram-positive bacteria has been observed in lichens containing usnic acid.

 Title    Zur Chemie der Roccellsäure On the Chemistry o f Roccellic Acid  
 Abstract    The isomerization of roccellic acid to threo-roccellic acid has been investigated. Reduction of dimethyl roccellate with LiAlH4 gave the corresponding diol which yielded on oxidation with Jones' reagent two isomeric 7-lactones. 1-Methyl roccellic amide has been transformed by a photochemical reaction to the <5-lactone acaranoic acid. Two copper complexes of roccel-limide have been prepared.

 Title    Chemical Investigation of the Lichen Species Anaptychia fusca, Peltigera canina, and Omphalodiscus spodochrous  
 Abstract    The three lichen species A n aptych ia fusca, P eltig era canina, and O m ph alodiscu s spodochrous have been studied with regard to their chemical content. Atranorin, gyrophoric acid, tenuiorin, allantoin, taurine, linoleic acid, a new sterol-C31H5202 , and waxes have been determined. The identity of the compounds was established by consideration of infrared, mass and nuclear magnetic resonance spectra. Besides, thin layer and column chromatographic techniques were used in this work.

 Title    Studies on the Chemistry of Lichens, XIX. New Amino Compounds from Anaptychia fusca and Several Stereocaulon Species  
 Abstract    The lichen Anaptychia fusca and several Stereocaulon species have been chem ically investigat­ ed with regard to their content o f unknown ninhydrin-positive com pounds. N ew aliphatic and alicyclic, am ino com ponents isolated from water extracts o f these lichen species have been charac­ terised as aminopentitol, am inohexitol and aminocyclitetrol. To our knowledge, this is the first time that com pounds such as these have been found in lichen material. A m inopentitol and am ino­ cyclitetrol appear to be characteristic constituents o f Anaptychia fusca, whereas am inohexitol has been found in several species o f Stereocaulaceae.

 Title    Screening of Aromatic Secondary Lichen Substances by High Performance Liquid Chromatography  
 Abstract    A simple HPLC m ethod is described which allows screening and accurate quantification o f aro­ matic secondary lichen substances. U sing a linear water-methanol gradient on a reversed-phase column packing (LiChrosorb RP-8) 13 aromatic lichen products were resolved within 55 min. With 8 arbitrarily selected lichens the application o f the described m ethod is demonstrated.

 Title    Species Alectoria fremontii and Its A ssociated Bark Substrate o f Pinus silvestris  
 Abstract    The element concentration o f the lichen species Alectoria frem ontii and its substrate (bark o f Pinus silvestris) were studied. It appeared that the content o f all the investigated elements, except for vanadium, was higher in the lichen samples than that in the corresponding bark samples. Analysis-of-variance procedure has demonstrated that the concentration o f N , P, S, Se, V, Hg and U in lichen samples appeared to change significantly in samples gathered from two different height-zones on the stems above ground level. However, this was not the case with the bark samples. The elements Se, V, Hg, U , Co and Mo determ inations o f the samples were performed by neutron activation m ethods.

 Title    Studies on the Chemistry of the Lichen Genus Umbilicaria Hoffm  
 Abstract    The aromatic com pounds o f more than 400 specimens o f 33 species o f the lichen genus Umbilicaria have been investigated by HPLC. Additionally to gyrophoric, hiascic, lecanoric, ovoic and umbilicaric acids, atranorin, norstictic and stictic acids, the new depside crustinic acid has been found. Structure elucidation o f crustinic acid was made by means o f HPLC cochromatography, N M R , UV and mass spectrometry. N ow the secondary product patterns o f Umbilicaria species are discussed and their significance for systematic purposes is shown.

 Title    Chemical Constituents of the Lichen Stereocaulon azoreum  
 Abstract    Column chromatography of the acetone extract of the lichen Stereocaulon azoreum afforded several substances identified by chemical and spectral means; a-amyrin, lupeol, taraxerol, ursolic acid, ergosterol peroxide, brassicasterol, cerevisterol, stictic acid and an acetone-con-densation derivative, lobaric acid.

 Title    Revised Structure of Haemoventosin  
 Abstract    The structure of the lichen pigm ent haem oventosin has been revised to 3,4,6,9-tetrahydro-5,10-dihydroxy-7-m ethoxy-3S-m ethyl-l,6,9-trioxo-l H-naphtho-[2,3-c]pyran (3), mainly on the basis of long-range <3C/<3H correlations observed in 2 D HM BC NMR experiments and long-range <5H/<5D isotope effects observed in partial deuteriation experiments with 10-0-acetylhaemoventosin; ortho-and /?öra-quinonoid structures were distinguished by means of the transacetylation inferred in the sodium dithionite reduction of lO-O-acetylhaemo-ventosin.
