Objective(s) The aim of this study was to search for new antiviral agents from herbal medicines. Ethanol extracts of C. semipervirens, C. semipervirens var. horizontalis and C. semipervirens cv. Cereiformis were used in experiments to test their influence on herpes viruses (HSV-1). Materials and Methods HeLa cells monolayers were infected with herpes viruses (HSV-1). Antiviral activity of th...

As part of our search for sedative substances from natural sources, we isolated two novel amino acid amides connected with the fructopyranose, kwansonine A (1) and kwansonine B (2), together with three known amino acid amides, longitubanine A (3), longitubanine B (4), and pinnatanine (5), from Hemerocallis fulva L. var. sempervirens (ARAKI) M. HOTTA. The structures of 1 and 2 have been determin...

Solanum elaeagnifolium Cav. is one of the most invasive plant species worldwide that colonizes crops and human disturbed lands, while it appears at edge forest ecosystems. Its control still remains an unsolved problem around world. Understanding its distribution under predicted climate change, could contribute to effective management conservation ecosystems in future. This research was conducte...

La contaminación con metales pesados es un problema grave a nivel mundial y en algunas regiones de México. En las ciudades, esto se debe principalmente residuos o desechos la industria al flujo vehicular principalmente. El presente estudio está enfocado determinar concentración (Cd, Cr, Pb V) hojas especies arbóreas (Pinus halepensis Mill., Cupressus sempervirens L. Prosopis spp.). Estas fueron...

Cupressaceae pollen is responsible for winter respiratory allergies in the Mediterranean area. Pollen grains of this diverse family share same characteristics under light microscopy. Consequently, partial contribution each species to airborne spectrum cannot be determined with conventional aerobiological methods. Studies on major aeroallergens offer better information allergic sensitization and...

In flammability assessment, the terpene effect is usually studied using their total or subgroup content, missing, therefore, information that could be provided by molecules themselves. this study, specific role of terpenes on leaf was sought comparing different levels identification—total, (i.e. mono-, sesqui-, and diterpene), single compound—as well as interactions with fuel moisture content (...

during past few years, the cupressus arizonica has been abundantly planted in tehran, causing a significant increase of allergic diseases from the middle of winter to the beginning of spring. the aim of this study was the comparison of pollen protein content in two major varieties of c. arizonica planted in tehran, including c. arizonica var. arizonica and c. arizonica var. glabra , in order to...
