 Title    Sesquiterpenoids and Phenolics from Crepis conyzifolia  
 Abstract    From the roots of Crepis conyzifolia, two new and two known guaianolides were isolated together with three known phenylpropanoids. Structures of the new compounds were estab­ lished as 8ß-hydroxy-4ß, 15-dihydrozaluzanin C and 4ß, 15, llß , 13-tetrahydrozaluzanin C-3-O-ß-glucopyranoside by spectral methods. The identity of 8 -epiisolippidiol and dentalactone was also discussed.

 Title    Lentinellic Acid, a Biologically Active Protoilludane Derivative from Lentinellus Species (Basidiomycetes) [1]  
 Abstract    A new antimicrobial and cytotoxic sesquiterpenoid, lentinellic acid (1), has been isolated from submerged cultures of Lentinellus ursinus and L. omphalodes. The structure of the antibiotic was elucidated by spectroscopic methods and a single crystal X-ray analysis. 1 may be formed biogenetically by condensation of a protoilludane aldehyde 4 with a malonate unit.

 Title    Phellodonic Acid, a New Biologically Active Hirsutane Derivative from Phellodon melaleucus (Thelephoraceae, Basidiomycetes) [1]  
 Abstract    A new hirsutane derivative, phellodonic acid (1), has been isolated from fermentations of Phellodon melaleucus strain 87113. Its structure was elucidated by spectroscopic methods. The compound exhibits antibiotic activities towards bacteria and fungi. 1 is the first bioactive metabolite from cultures of a species belonging to the family Thelephoraceae.

 Title    Kuehneromycins A and B, Two New Biological Active Compounds from a Tasmanian Kuehneromyces sp. (Strophariaceae, Basidiomycetes)  
 Abstract    G erh ard E rk e l3, K irsten L o ren zen 3, Timm A n k ea, R obert V eltenb, A lb erto G im en ezb, and W olfgang Steglichb In a search for new inhibitors of RNA-directed DNA-polymerases kuehneromycin A (1) was isolated from fermentations of a Tasmanian Kuehneromyces species. Its structure was elucidated by spectroscopic methods. Kuehneromycin A (1) is a non-competitive inhibitor of avian myeloblastosis virus (Kj 200 ^i m) and moloney murine leukemia virus (K; 40 (.i m) reverse transcriptases. The second compound, kuehneromycin B (2) is a strong inhibitor of platelet aggregation stimulated with different inducers. In addition, both compounds exhibit cytotoxic and antimicrobial activities.

 Title    The Lipid and Resin Composition of Laretia compacta Phil, from the Andes of Chile  
 Abstract    The lipid/resin components of Laretia compacta were characterized by GC-MS and CSIA. The lipid components consist of «-alkanes, «-alkanoic acids and «-alkanols all with low car­ bon number maxima and high CPI values. The resin components are comprised of major amounts of tetracyclic diterpenoids with a minor content of mono-and sesquiterpenoids. The kaurene skeleton predominates with some phyllocladenes. Phytosterols are trace compo­ nents. The 6 13C data of the individual alkanes in the hydrocarbon fraction place this species in the C4 plant group.

 Title    9 ß-Hydroxymarasmic Acid and Other Sesquiterpenoids from Submerged Cultures of a Basidiomycete [1]  
 Abstract    9 ß-Hydroxymarasmic acid, a new sesquiterpenoid, marasmic acid and isovelleral were isolated from cultures of a basidiomycete. Comparison of the antimicrobial activity of the three natural compounds together with two n-butyl ether derivatives of marasmic acid revealed MICs against bacteria in the range of 0 .2 —20 ng/ml. The antifungal, cytotoxic and phytotoxic activities of isovelleral were similar to those exhibited by marasmic acid, whereas the marasmic acid deriva­ tives were considerably less active than the parent compound. Isovelleral was the only compound to show hemolytic activity.

 Title    Microbial Hydroxylation of Precursors of Sinensal  
 Abstract    In order to produce the important flavour com pound sinensal microbial co-hydroxylation o f farnesene and its sulfone derivative were investigated. W hile farnesene proved to be a poor substrate, its sulfone could be hydroxylated to the co-hydroxyfamesene sulfones in up to 27% yield. Some strains could discriminate between the yields products hycroxylated at different positions could also be isolated.
