Background & Aim: Feed additives have been widely used to stimulate appetite, improve growth performance and immune system function in livestock nutrition. For many years antibiotics have been used in livestock production to improve growth performance. Following the ban on the use of antibiotic growth promoters in animal feeds in European Union and increasing demand for organic...

background: nowadays, there's a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants. therefore, introduction of new natural antioxidants (especially those with plant origin) is very important. objective: the present study explores the chemical constitution and antioxidant activity of leaf extract of hyssopus officinalis l. and extract of aerial ...

the poultry industry has been outbreak with an intricate problem called coccidiosis from the beginning and undoubted coccidiosis is one of the most widespread poultry diseases especially among breeder herds and ancestor. so the interest in alternative methods for the control of coccidiosis has been dramatically increased in recent years, and it is necessary to look for methods which are adaptab...

In this work we analyzed the composition and structure of cultivable bacterial communities isolated from the stem/leaf and root compartments of two medicinal plants, Echinacea purpurea (L.) Moench and Echinacea angustifolia (DC.) Hell, grown in the same soil, as well as the bacterial community from their rhizospheric soils. Molecular PCR-based techniques were applied to cultivable bacteria isol...

Nowadays green synthesis of metal nanoparticles is a developing area of research. In this study, titanium dioxide nanoparticles were biosynthesized using an aqueous solution of Echinacea purpurea herba extract as a bioreductant. This is novel and interesting method for synthesis of TiO2 nanoparticles. The prepared titanium dioxide nanoparticles were characterized using ultraviolet-visible spect...

Extracts of Echinacea species have been used traditionally in North America for the control of symptoms of colds, influenza, and other diseases, and some of them have become very popular as “herbal medicines”. Recent studies have revealed that preparations derived from certain species and plant parts, but not all of them, possess potent antiviral activities, at non-cytotoxic concentrations, par...

Extracts of Echinacea purpurea (EP, purple coneflower) have been used traditionally in North America for the treatment of various types of infections and wounds, and they have become very popular herbal medicines globally. Recent studies have revealed that certain standardized preparations contain potent and selective antiviral and antimicrobial activities. In addition, they display multiple im...

Ongoing studies have developed strategies for identifying key bioactive compounds and chemical profiles in Echinacea with the goal of improving its human health benefits. Antiviral and antiinflammatory-antipain assays have targeted various classes of chemicals responsible for these activities. Analysis of polar fractions of E. purpurea extracts showed the presence of antiviral activity, with ev...
