New naturally occurring nitrogenous compounds 1 and 2, along with a new dimeric lignan glucoside 3, have been isolated from the ethyl acetate soluble fraction of Centaurea iberica. Their structures have been elucidated through spectroscopic techniques. All the isolated compounds showed significant platelet aggregation inhibition.

The extract containing sesquiterpene lactones of Centaurea iberica (Asteraceae) isolated was separated and a steroidal compound, which is stigmast-1,5-dien-3beta-ol, was purified. The chemical structure was established based on spectroscopic data (UV, IR, MS, 1H NMR, 13C NMR). Both the extract and the compound showed significant antioxidant and antimicrobial activities.

During a survey of saprophytic microfungi on decomposing woody, herbaceous debris and soil from different regions in Southern Europe, a wide range of interesting species of asexual ascomycetes were found. Phylogenetic analyses based on partial gene sequences of SSU, LSU and ITS proved that most of these fungi were related to Sordariomycetes and Dothideomycetes and to lesser extent to Leotiomyce...

El poeta Francisco Botelho de Moraes e Vasconcelos encarna con su vida y obra el ideal hombre letras iberico que, a caballo entre los siglos XVII XVIII, vivio Torre Moncorvo, Madrid, Coimbra, Barcelona, Lisboa Salamanca, recorrio tierras Francia Italia publico versos prosa en castellano, portugues tambien latin. Leer Fracisco como autor es, pues, un buen arranque para interpretar sus textos. Es...

Lallemantia is a medicinally important plant in the world. Due to interspecific hybridization and horizontal gene transfer, spices relationship delimitation on genus difficult based different molecular markers. Therefore, selecting appropriate marker can be important. Fingerprinting techniques continue used for genomic profiling characterization of germplasm establishment identity varieties/hyb...
