Biosystematic and chemosystematic studies in five South American species of Conyza (Asteraceae) Boletín de la Sociedad
Urdampilleta,Juan D.; Amat,Aníbal G.; Bidau,Claudio J.; Kolb Koslobsky,Nicolás.
The composition of the essentials oils of five species of Conyza Less from Argentina was determined by Gas Chromatography-Mass Spectrometer. This composition is associated to morphological and cytogenetic characters. The monoterpenes constitute more than 60% of the essential oils in C. blakei, C glandulitecta, C. sumatrensis var. sumatrensis and C. sumatrensis var. floribunda, in which limonene is the predominant compound. In C. bonariensis and C. primulaefolia the monoterpene content constitute less than the 40%. C. bonariensis presents only 13% limonene, while in C. primulaefolia it is absent. The similarity analysis of monoterpenes showed a relationship between the morphological and cytogenetic analysis, and the monoterpene content character seems to be...

Chemosystematic aspects of polyisoprenylated benzophenones from the genus Clusia Anais da ABC (AABC)
Anholeti,Maria Carolina; Paiva,Selma R. de; Figueiredo,Maria Raquel; Kaplan,Maria Auxiliadora C..
Benzophenone derivatives are special metabolites that arouse great scientific interest. The Clusiaceae family is known for producing large amounts of benzophenone derivatives with several isoprene residues on their structures, which are responsible for the observed complexity and structural variety in this class of substances, and also contribute to their biological activities. Clusia is an important genus belonging to Clusiaceae, with 55 different polyisoprenylated benzophenones identified so far. These substances were analyzed from biosynthetic and chemosystematic points of view, allowing the determination of characteristics regarding their production, accumulation and distribution within this genus. Polyisoprenylated benzophenones found in Clusiashowed...

The phylogenetic position of Rhopalostroma as inferred from a polythetic approach Naturalis
Stadler, M.; Fournier, J.; Gardt, S.; Peršoh, D..
The xylariaceous genus Rhopalostroma comprises a small conglomerate of stromatic, angiospermassociated pyrenomycetes, which have so far exclusively been reported from the palaeotropics, above all from tropical Africa and South Asia. Morphological and chemotaxonomic studies had suggested their close relationship to the genera Daldinia and Hypoxylon. However, those results were mainly based on herbarium specimens, and no molecular phylogenetic data were available on Rhopalostroma. During a foray in Côte d’Ivoire, fresh material of R. angolense was collected, cultured and studied by microscopic methods and by secondary metabolite profiling using high performance liquid chromatography coupled with diode array and mass spectrometric detection. In addition, ITS...
