یکی از فاکتورهای تاثیرگذار در تعیین زمان مناسب ورود و خروج دام از مرتع مطالعه فنولوژی گیاهان میباشد. علاوه بر آن با مطالعه فنولوژی زمان مناسب جمع آوری بذر، ارزش غذایی گیاهان و مدیریت مرتع مشخص خواهد شد. در این تحقیق مراحل مختلف فنولوژی 10 گونه از مهمترین گیاهان مرتعی در منطقه سرعلیآباد گرگان به مدت 4 سال(2007-2010) به منظور شناخت تاریخها و مدت زمان بروز پدیدههای مهم فنولوژیکی انجام...
Background & Aim: The present study was aimed to evaluate and compare the antibacterial activity of Schrophularia striata Boiss. andStachys schtschegleevii Sosn. Extracts against seven clinical isolates. The test isolates were Streptococcus agalactiae, Enterococcus faecalis, Staphylococcus saprophyticus, E. coli, Klebsiella pneumoniae, Proteus mirabilis an...
چکیده: جنس مریم گلی(salvia.l) از تیره نعناعیان با حدود 900 گونه گسترش وسیعی در سرتاسر دنیا دارد. مراکز اصلی تنوع جنسsalvia نواحی مدیترانه ای آسیای مرکزی آمریکای و جنوب آفریقاست. این جنس دارای 58 گونه علفی و پایا در ایران است که 17 گونه آن انحصاری است. اعضاء این جنس دارای متابولیت ثانویه بسیاری نظیر اسانس ها و ترکیبات فنلی است که دارای خواص دارویی بوده و در مقابل علف خوارها وپاتوژن ها نقش های ت...

The mineral contents of Centaura leave and seeds were determined by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES). Macro element concentrations (P, K, Ca, Mg and S) of samples were found at high levels. K was established at high level in both leave and seed samples of Centaurea. While K contents of leaves changes between 7254.10 mg/kg (Centaurea lycaonica) and 26396.36 m...
Centaurea solstitialis, commonly known as yellow starthistle, is an invasive plant listed as a noxious weed in the western areas of North America and is the target of classical biological control, which involves release of herbivores known to be specific to this plant. These insects often choose their host plant on the basis of the volatile organic compounds (VOCs) emitted. Accordingly, volatil...
Members of the genus Centaurea (Asteraceae) have been used in traditional plant-based medicine. The methanol extracts of twelve Centaurea species, of which five are endemic to Turkey flora, were screened for antibacterial activity against four bacteria (Escherichia coli, Bacillus cereus, Salmonella enteritidis, Staphylococcus aureus). The antibacterial activity was evaluated by the microdilutio...
Many of the best-selling anticancer drugs are plant-derived. We tested for the anticancer properties of extracts isolated from Centaurea ainetensis, a plant species endemic to Lebanon and which is often used in folk medicine. We performed bioassay-guided fractionation of Centaurea ainetensis extracts using a panel of normal and neoplastic murine cells to identify a component that is associated ...
Centaurea L. is a genus of the family Asteraceae that comprises over 600 taxa. Representatives of the Centaurea genus were used as natural medications for many diseases. Methanolic-aqueous extracts from aerial parts of two Centaurea species: C. borysthenica Gruner and C. daghestanica (Lipsky) Wagenitz were studied for their polyphenolic composition and potential protective effect on cardiomyocy...
BACKGROUND Biological invasions are fundamentally biogeographic processes that occur over large spatial scales. Interactions with soil microbes can have strong impacts on plant invasions, but how these interactions vary among areas where introduced species are highly invasive vs. naturalized is still unknown. In this study, we examined biogeographic variation in plant-soil microbe interactions ...
