 Title    Hans  
 Abstract    From the "head space" * o f Harpocera thoracica (M iridae; H em iptera) six monoterpenes have been isolated and identified by G LC and MS d ata in comparison with authentic reference substances. Predom inant component was geranyl acetate. Apart from this, the alcohols geraniol and nerol, neryl acetate, and the corresponding aldehydes geranial and neral could be identified.

 Title    Chemical Composition and Biological Activities of the Black Sea Algae Polysiphonia denudata (Dillw.) Kutz. and Polysiphonia denudata f fragilis (Sperk) Woronich  
 Abstract    The two investigated algae had almost identical sterol composition, but there were signifi­ cant differences in the com position o f the polar com ponents and especially in the com posi­ tion of the volatiles. P. denudata f. fragilis extracts possessed a stronger biological activity (antibacterial, antifungal and toxicity against Artem ia salina). D espite the minute m orpholog­ ical differences between the two algae, we recommend P. denudata f. fragilis to be regarded as P. denudata subsp. fragilis.

 Title    Chemical Composition and Antibacterial Activity of Brazilian Propolis  
 Abstract    Four samples of Brazilian propolis were investigated by GC/MS of different fractions. 32 volatile compounds, (10 of them new for propolis), as well as 12 more polar compounds (one of them new for propolis) were identified. Antibacterial activity was found in some propolis fractions.

 Title    Accumulation of Volatile Flavour Compounds in Liquid Cultures of Kluyveromyces lactis Strains  
 Abstract    The accumulation o f volatile flavour constituents in liquid cultures o f three Kluyverom yces lactis strains was studied after cultivation on defined culture m edia containing glucose as carbon source, yeast extract, vitamines, and different additional nitrogen com pounds. Besides short-chain alcohols and esters (fruit esters), 2-phenylethyl alcohol, phenylacetaldehyde, and 2-phenylethyl esters could be identified by gas chrom atography and coupled gas chrom atog-raphy-mass spectrometry. Although the com position o f these com pounds was qualitatively comparable within the three strains investigated, quantitative differences were significant and strain-dependent reactions to the culture m edium could be observed.

 Title    Identification by Gas Chromatography-Mass Spectrometry of 150 Compounds in Propolis  
 Abstract    Propolis was analyzed by gas chromatography-mass spectrometry for both its headspace volatiles and for the less volatile com ponents o f its alcoholic extract (propolis balsam). 181 peaks were located o f which 171 representing 150 compounds were identified, including 28 identified in propolis for the first time. The majority o f compounds were typical o f poplar bud exudate.

 Title    Glandular Trichomes and the Yolatiles Obtained by Steam Distillation of Quercus robur Leaves  
 Abstract    R a lf E n g e lb, P a u l-G e rh a rd G ü lz 3, T h o rs te n H e rrm a n n 3, a n d A d o lf N a h r s te d tb G landular trichom es in form of long stretched tubes are present on the low er leaf side of Quercus robur as shown by scanning electron microscopy. The glands contain an essential oil, which was isolated by steam distillation together with volatile waxy com ponents of the leaves in an am ount of 0.025% of fresh leaves. The product of steam distillation was analyzed by GC-MS. Identification of com pounds is based on comparison of their mass spectral data with those of authentic samples in com bination with retention indices and MS data using the SeKoMS (Search Kovats Indices and Mass Spectra) Library. A ltogether 184 com ponents of the product of steam distillation were separated, 155 of which could be identified, another 7 were tentatively assigned. T hree groups of substances according to their chemical com posi­ tion are found: hexenyl derivatives and some acetals (32%); terpenes including m onoterpenes (4%), sesquiterpenes and diterpenes (21%); and alkane derivatives (35%). The residual 8% consist of benzyl alcohol, com pounds which stem from the degradation of carotenes, and mis­ cellaneous constituents.
