OBJECTIVE To make an useful identification method for the molecule of DNA on 3 herbs of Artemisia genus and compare the differences of the genes of Korean and Chinese species of Artemisia. METHODS Sequence of 3 herbs (Artemisia sacrorum Ledeb., Artemisia iwayomogi Kitam. and Artemisia capillaris Thunb.) was determined by PCR sequence system. DNA was extracted from rDNA/ITS (internal transcrib...
Plant roots interact with a wide variety of rhizospheric microorganisms, including bacteria and the symbiontic arbuscular mycorrhizal (AM) fungi. The mycorrhizal symbiosis represents a series of complex feedbacks between plant and fungus regulated by their physiology and nutrition. Despite the widespread distribution and ecological significance of AM symbiosis, little is known about the potenti...
BACKGROUND Artemisia frigida Willd. is an important Mongolian traditional medicinal plant with pharmacological functions of stanch and detumescence. However, there is little sequence and genomic information available for Artemisia frigida, which makes phylogenetic identification, evolutionary studies, and genetic improvement of its value very difficult. We report the complete chloroplast genome...
در این آزمایش به منظور بررسی اثر مصرف عصاره آبی الکلی برگ گیاه آرتمیزیا در دو سطح مختلف بر عملکرد، فراسنجه های خونی، پاسخ ایمنی و جمعیت باکتری های سکوم جوجه های گوشتی در مقایسه با آنتی بیوتیک محرک رشد، 192 قطعه جوجه گوشتی سویه تجاری راس 308، در قالب طرح کاملا تصادفی با 4 گروه آزمایشی، 4 تکرار و 12 مشاهده در هر تکرار مورد استفاده قرار گرفت. گروههای آزمایشی شامل: 1) گروه آزمایشی شاهد دریافت کنن...
چکیده زمینه و هدف: برای بسیاری از سرطان ها درمان کامل وجود ندارد و اغلب به مرگ بیمار ختم می شوند. در این راستا اولین مرحله ی تحقیقاتی، ارزیابی کشندگی فراکشن های گیاهی بر سلول های سرطانی است. اعضای خانواده ی آرتمیزیا گیاهان دارویی مهمی در سرتاسر دنیا محسوب می شوند. در این تحقیق، تاثیر ضدسرطانی فراکشن های هفت گونه ی آرتمیزیای بومی ایران بر سلول های سرطانی و نرمال بررسی شد. روش بررسی: فراکشن های ا...
The medicinal plants are of great use in pharmaceutical, cosmetic, agricultural and food industry. The efficacy of some herbal products is beyond doubt, the most recent examples being Silybum marianum (Linn.) Gaertn (Silymarin), Artemisia annua Linn. (Artemesinin) and Taxus baccata Linn.(taxol). Randomized, controlled trials have proved the efficacy of some established remedies, for instance Zi...
The aromatic compounds of Artemisia annua were extracted by supercritical carbon dioxide. Supercritical carbon dioxide extraction of volatile flavor compounds from Artemisia annua was performed at pressure 150bar and temperature 40oC. The flow rate of CO2 was 20 g/min and the flow rate of ethanol as an entrainer was 5% of CO2 used. The extraction time was 1 h. The trapped sample by cold trap 1 ...
Topography is an important factor in determining vegetation patterns in grasslands. We collected frequency of occurrence data from transects on dune tops, south-facing slopes, north-facing slopes, and interdunal valleys in the eastern Sandhills of Nebraska to determine the effect of topographical position on plant species composition. We used canonical discriminant analysis to separate the four...
Greater sage-grouse (Centrocercus urophasianus) populations have declined from 66 to 92% during the last 30 years in Canada, where they are listed as endangered. We used radiotelemetry to examine greater sage-grouse nest and brood habitat use in Alberta and assess the relationship between habitat and the population decline. We also identified the patch size at which sage-grouse were selecting n...
Sagebrush (Artemisia spp.) in North America is an abundant native plant species that is ecologically and evolutionarily adapted to have a diverse array of biologically active chemicals. Several of these chemicals, specifically polyphenols, have antioxidant activity that may act as biomarkers of biotic or abiotic stress. This study investigated the spatial variation of antioxidant capacity, as w...
