BACKGROUND AND AIMS Juniperus excelsa is an important woody species in the high mountain ecosystems of the eastern Mediterranean Basin where it constitutes the only coniferous species found at the tree line. The genetic diversity within and among J. excelsa populations of the eastern Mediterranean Basin is studied in the light of their historical fragmentation. METHODOLOGY Nuclear microsatell...
The essential oils of branchlets and fruits of Juniperus excelsa subsp. excelsa and Juniperus excelsa subsp. polycarpos were examined for their antioxidant activity. The compositions of the essential oils were studied by GC and GC-MS. To evaluation the antioxidants activity of the volatile oils, pure components and positive controls at different concentrations, thin-layer chromatography (TLC) s...
هدف اصلی مطالعات تنوع ژنتیکی، شناخت ویژگی های ذاتی و قابل توارث گیاهان و تلاش برای حفاظت از این ویژگی-های ذاتی است. ارس (juniperus polycarpos k.koch) از تیره سرو (cupressaceae)، یکی از مهم ترین گیاهان پرستار در کوهستان های صخره ای خشک و نیمه خشک است. شمال شرق به دلیل داشتن چندین زیستگاه برای این گیاه، یکی از بزرگترین ذخایر ژنتیکی ارس در کشور ایران است. تخریب بیش از حد این گیاه در سال های اخیر، ...
BACKGROUND Cutaneous leishmaniasis is one of the highly prevalent endemic diseases in the Middle East and North Africa. Many treatment modalities have been recommended for this condition but success rates remain limited. Herbal remedies have also been used for treatment but evidence-based clinical trials with these products are sparse. In-vitro and in-vivo studies have shown the anti-leishmania...
Background and objectives: Juniperus excelsa is a flowering plant that has been applied as traditional medicine for treatment of various disorders such as dysmenorrhea, bronchitis and colds, jaundice and tuberculosis. The aims of the present study were analyzing J. excelsa essential oil and investigation of its cytotoxic activity on three breast cancer cell li...
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...
BACKGROUND AND AIMS Juniperus excelsa M.-Bieb. is a major forest element in the mountains of the eastern part of Mediterranean and sub-Mediterranean regions. This study comprises the first morphological investigation covering a large part of the geographical range of J. excelsa and aims to verify the congruency between the morphological results and molecular results of a previous study. METHO...
