the relocation of nutrients and water fluxes to the forest floor varies spatially due to partition of rainfall into throughfall and stemflow by tree canopies. in this study, nutrient concentrations of rainfall and stemflow were measured for seven rainfall events in chaboksar area in the hyrcanian ecozone of iran composed of juglans regia linn and cup. sempervirens l. var. fastigiata where such ...

Five Hesperocyparis (Cupressus) abramsiana groves were analyzed by Inter-Simple Sequence Repeats (ISSRs). ISSRs analyses revealed geographical differentiation among the groves (= Silba's subspecies) with the Butano Ridge grove being the most distinct in both ISSRs and terpenoids. Combined ISSR and terpenoid data support the recognition of Hesperocyparis. abramsiana var. abramsiana and Hesperocy...

The aim of the present study was to investigate CNS depressant activity of methanolic extract of Gelsemium sempervirens roots. G. sempervirens Ait (Loganiaceae) is used traditionally in the treatment of migraine, neuralgia, rheumatism, restlessness, mental irritability, insomnia and ovarian and uterine pain. The plant was found to contain alkaloids gelsemine, gelseminine, gelsemoidine and gelse...

A new species of conifer was recently discovered in northern Vietnam. In a preliminary phylogenetic analysis of morphological data a possible sister species, Chamaecyparis nootkatensis (D. Don) Spach, was identified; however, because of the presumed phylogenetic remoteness of these two species to the remainder of the Cupressaceae, a new genus-Xanthocyparis-was described to accommodate both spec...

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 the p...
