DOR: 98.1000/1735-0891.1398.27.45.53.1.1578.41 قره قاط یکی از گیاهان دارویی مهم در طب سنتی است که بهمنظور کاهش قند خون و تنظیم فشار خون از دیرباز در ایران کاربرد دارد.در این تحقیق تأثیر اکسین، اسید جیبرلیک، کازئین هیدرولایسیت، پوترسین و سالیسیلیک اسید بر استقرار ورشد ریزنمونه های قره قاط و میزان ترکیبات ثانویه آنتوسیانین، فلاونوئیدی و فنل تام بررسی شد. ریزنمونههای تک گرهی و جوانه ...
طبیعت منبع غنی از ترکیب های دارویی می باشد. امروزه در کشور های در حال توسعه به دلیل بروز عوارض جانبی ناشی از مصرف دارو های شیمیایی، استفاده از دارو های گیاهی در درمان انواع بیماری ها مورد توجه زیادی قرار گرفته است و تحقیقات در زمینه استخراج ترکیب های فعال بیولوژیکی از گیاهان به سرعت در حال انجام می باشد. قره قاط (vaccinium arctostaphylos) درختچه ای متعلق به خانواده ericaceae می باشد که از دیر ب...
Phylogenetic relationships within subfamily Arbutoideae (Ericaceae) were estimated using parsimony and maximum likelihood analyses of sequence data from the ITS region and part of the large subunit of nuclear ribosomal DNA. The data support the monophyly of Arctostaphylos, Arctous, and Comarostaphylis, but suggest that Arbutus is not monophyletic, with Mediterranean Basin species more closely r...
Freezing stress affects all plants from temperate zones to the poles. Global climate change means such freezing events are becoming less predictable. This in turn reduces the ability of plants to predict the approaching low temperatures and cold acclimate. This has consequences for crop yields and distribution of wild plant species. C-repeat binding factors (CBFs) are transcription factors prev...
Changes are made in the nomenclature of species and subspecies in the genus Arctostaphylos (Ericaceae). In this study, the focus is on species found in the coast ranges of California. Changes are made in A. nortensis from the area around the Oregon border with California, in the A. nevadensis complex in the North Coast Ranges, in the A. nummularia complex of the north to central coast, in the A...
The joint interpretation of phenology and nutritional metabolism provides important data on plant tissues reactivity and the period of gall induction. A population of Aspidosperma macrocarpon (Apocynaceae) with leaf galls induced by a Pseudophacopteron sp. (Psylloidea) was studied in Goiás state, Brazil. Assuming the morphological similarity between host leaves and intralaminar galls, a gradien...
BACKGROUND Urinary tract infection is the most common bacterial infection in the community, mainly caused by Escherichia coli (E coli). Due to its high incidence and recurrence, problems are faced in the treatment with antibiotics. Cranberry being herbal remedy have long been the focus of interest for their beneficial effects in preventing urinary tract infections. This study was conducted to a...
A method was developed to distinguish Vaccinium species based on leaf extracts using nuclear magnetic resonance spectroscopy. Reference spectra were measured on leaf extracts from several species, including lowbush blueberry (Vaccinium angustifolium), oval leaf huckleberry (Vaccinium ovalifolium), and cranberry (Vaccinium macrocarpon). Using principal component analysis, these leaf extracts wer...
