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 Wild vegetables in the Mediterranean Basin are still often consumed as a part of the diet and, in particular, there is a great tradition regarding their use in Sicily. In this study, an ethnobotanical field investigation was carried out to (a) identify the wild native taxa traditionally gathered and consumed as vegetables in Sicily, comparing the collected ethnobotanical data with th...

This interesting disease which is not altogether uncommon in the province of Beliar appears to be clinically identical with that described by Manson as occurring in certain parts of America. The malady is the result of a Blue Bottle Fly (Pycnosoma) depositing its larvae in a slight abrasion of, or in the unbroken mucous membrane of, the nasal fossa of the patient. The larvae burrow into the del...

Background and objectives: Iran owns a rich and prestigious heritage of medicinal herbs but the majority of these plants have not yet undergone chemical, pharmacological and toxicological studies. In the present study some species form northern parts of Iran were evaluated for cytotoxicity. Methods: Sixteen medicinal plants were extracted with methanol and screened for their cytotoxic activitie...

In a microcosm experiment, I tested how species composition, species richness, and community age affect the susceptibility of grassland communities to invasion by a noxious weed (Centaurea solstitialis L.). I also examined how these factors influenced Centaurea’s impact on the rest of the plant community. When grown in monoculture, eight species found in California’s grasslands differed widely ...

Wildflowers attract wildlife, increase pollinator habitat, and enhance the aesthetic value of landscape. Wildflower establishment is increasingly part an effort to reduce maintained turfgrass on golf courses, lawns, other environments. Weed competition decreases wildflower results in poor long-term stands. Research was conducted a controlled environment investigate tolerance species common post...

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 mg/kg...
