Male and female leaves and fruits of eleven different taxons of Iranian conifers (Cupressus sempervirens var. horizontalis, C. sempervirens var. sempervirens, C. sempervirens cv. Cereifeormis, Juniperus communis subsp. hemisphaerica, J. excelsa subsp. excelsa, J. excelsa subsp. polycarpos, J. foetidissima, J. oblonga, J. sabina, Platycladus orientalis and Taxus baccata) were collected from diff...

Background: Because reactive oxygen species (ros) contribute to the pathogenesis of various acute and chronic liver diseases, dietary antioxidants and drugs from herbal origins have been proved to be beneficial as therapeutic agents in reversing hepatotoxicity and oxidative stress. The objective of this study was to investigate the protective effect of an aqueous extract from smilax excelsa l. ...

Brazil nut, the Bertholletia excelsa seed, is one of the most important non-timber forest products in the Amazon Forest and the livelihoods of thousands of traditional Amazonian families depend on its commercialization. B. excelsa has been frequently cited as an indicator of anthropogenic forests and there is strong evidence that past human management has significantly contributed to its presen...

During the study on rust mycobiota of Central Alborz, several rust infected specimens belonging to Salicaceae family including Populus and Salix species were investigated. Populus nigra, P. euphratica, Saix alba and S. excelsa were infected by various Melampsora species. Uredinial (II) and telial (III) stages of rust were present on infected plants. According to morphological characters, five f...

objective(s) the cytotoxic effects of crude ethanol extracts of some previously tested iranian conifers  on tumor cell lines have motivated us to screen different parts of two subspecies in these genus. materials and methods terminal branchlets and berries of juniperus excelsa subsp. excelsa and j. excelsa subsp. polycarpos were collected, dried and extracted with ethanol/h2o (80/20 v/v) via pe...

The methanol extract from the leaves of Spathelia excelsa yielded six alkaloids: 2-(12-oxo-tridecanyl)-3-methoxy-4-quinolone, 2-(10-hydroxy-10-methyldodecanyl)-3-methoxy-4-quinolone, 2-(11-hydroxy-11-methyldodecanyl)-3-methoxy-4-quinolone, 2-(12-hydroxytridecanyl)-3-methoxy-4-quinolone, 7-hydroxy-2-(3-hydroxy-3-methylbutyl)-4-quinolone and 6-hydroxy-2-(3-hydroxy-3-methylbutyl)-4-quinolone, in a...

The genus Juniperus L. (Cupressaceae), an aromatic evergreen plant, consists of up to 68 species around the world. We classified five species of Juniperus found in Iran using molecular markers to provide a means for molecular identification of Iranian species. Plants were collected (three samples of each species) from two different provinces of Iran (Golestan and East Azarbayejan). The DNA was ...
