Leaf and oleoresin fractions of both alcoholic and petroleum ether extracts of Araucaria bidwillii exhibited significant prolongation of pentobarbitones sleeping time at a dose of 300 and 100 mg/kg body weight respectively in mice. This effect is more pronounced for oleoresin than the leaf extracts. Further, the two extracts seem to possess analgesic effect comparable to aspirin by writing meth...

BACKGROUND Performing chloroplast DNA (cpDNA) isolation is considered a major challenge among different plant groups, especially conifers. Isolating chloroplasts in conifers by such conventional methods as sucrose gradient and high salt has not been successful. So far, plastid genome sequencing protocols for conifer species have been based mainly on long-range PCR, which is known to be time-con...

The evolutionary history, divergence times and phylogenetic relationships of Uleiella chilensis (Ustilaginomycotina, smut fungi) associated with Araucaria araucana were analysed. DNA sequences from multiple gene regions and morphology were analysed and compared to other members of the Basidiomycota to determine the phylogenetic placement of smut fungi on gymnosperms. Divergence time estimates i...
