The pyrolytic kinetics of Phragmites australis was investigated using thermogravimetric analysis (TGA) method with linear temperature programming process under an inert atmosphere. Kinetic expressions for the degradation rate in devolatilization and combustion steps have been obtained for P. australis with Dollimore method. The values of apparent activation energy, the most probable mechanism f...

The one-seeded, serrate leaf margined junipers of Southwestern United States and northern Mexico consist of J. angosturana, J. californica, J. coahuilensis var. arizonica, J. c. var. coahuilensis, J. monosperma, J. pinchotii, J. occidentalis var. australis, J. o. var. occidentalis and J. osteosperma. Recent nrDNA and trnC-trnD sequence data were compared with RAPDs analysis and two of the taxa ...

The resistance of the scorpion Androctonus australis to its own venom, as well as to the venom of other species, was investigated. A comparison of the electrical and pharmacological properties of muscle and nerve fibres from Androctonus australis with those from the crayfish Procambarus clarkii enabled us to understand the lack of effect of scorpion venom (110-180 microg ml-1) and purified toxi...

Background: Plantago species contain aucubin and catalpol iridoid glycosides used in traditional medicine for many purposes. Objectives: To accelerate the utilization of species, research should be focused on introducing advanced purification detection methods. In this regard, therapeutic activities compounds are mentioned to confirm their effectiveness medicinal uses. Methods: An extensive lit...

The distribution of 14 iridoid glucosides in 14 Plantago L. species (44 samples corresponding to 18 taxa) was shown. P. tenuiflora and P. gentianoides were studied for iridoids for the first time. The iridoid patterns showed a good correlation with morphological and other chemical features of the representatives of genus Plantago. The studied species are grouped together according to the iridoi...

O presente estudo trata-se de uma revisão sistemática sobre as possíveis interações medicamentosas do uso plantas medicinais e fitoterápicos incluídos na Relação Nacional Medicamentos Essenciais (RENAME). Para isso, foram pesquisadas entre medicamentos alopáticos medicinais: alcachofra, aroeira, babosa, cáscara sagrada, espinheira-santa, garra diabo, guaco, hortelã pimenta, isoflavona soja, pla...

The chemical composition of plant polyphenols Plantago major L. and lanceolata growing in Uzbekistan was studied. More than 20 compounds, including 7 flavonoids, 9 phenolic acids, 8 hydrolysable tannins, the ages which have been determined using physicochemical methods research isolated from plants. From P. L., along with well-known such as gallic acid, rutin, luteolin, isorhamnetin, hyperoside...

Accumulation of heavy metals from various oxides with adsorbed cadmium by wetland plant Phragmites australis was studied to evaluate the fate of heavy metals in the sediment of constructed wetlands. Hoagland solution was used as nutrition supply, and single metal oxide with adsorbed cadmium was applied as contaminant to study the accumulation characteristics of cadmium and the substrate metals ...

The Australian pygopodid lizard genus Delma is characterised by morphologically conservative but genetically divergent lineages and species. An initial assessment of molecular and morphological variation in Delma australis Kluge, 1974 throughout its main distribution in Western and South Australia reveals at least two undescribed species that are presently included under this epithet. Here we d...
