Preparations of echinacea and ginseng likely comprise the most popular and commercially successful combination of medicinal plant products in North America. Interestingly, the development of Echinacea species for medicinal purposes stems from use by indigenous American people, but research has been conducted predominantly in Germany (Bauer and Wagner 1991). On the other hand, the reputation of ...

We evaluated the branching response of established containerized perennials to spray or drench applications of Augeo (OHP, Inc.) applied during active growth as compared to Configure (Fine Americas, Inc.). Crops tested included Gaillardia ‘Gallo Yellow,’ Echinacea ‘Sombrero Hot Pink,’ and Phlox paniculata ‘Laura.’ Treatments were applied about 2 weeks after plugs were planted in 3.4-liter conta...

previous studies have shown antiviral effect of echinacea and elderberry preparations against human influenza viruses in vitro. to investigate the in vivo antiviral effect of these herbs on avian h9n2 influenza virus, amantadine and two standardized commercial extracts of echinacea purpurea (ef) and sambucus nigra (sam) were used in broiler chickens infected with h9n2 strain of the virus. ef, s...

Tissue culture of Echinacea angustifolia allows for selection and rapid multiplication of genetically superior clones. In this study, temporary immersion liquid bioreactor (RITA system), synthetic seed technology and semi-solid culture conditions were evaluated for shoot multiplication efficiency. After 25 days of culture, the highest multiplication rate was observed in explants cultured in tem...

background: applications of natural ingredients not only increase the shelf life of food but also omit the problems of synthetic preservatives compounds. objective: cinnamon verum essential oil (cveo 0.05, 0.1, 0.15%) and echinacea purpurea extract (epe 0.25, 0.5, 0.75%) were added to kolompe (a traditional cookie in kerman-iran) and their antioxidant and antimicrobial effects were compared wit...

background: oxidation of lipids causes reduction of different properties of products that contains lipids. nowadays, there is a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants such as bha, bht and tbhq. objective: in this study, extract of aerial parts of echinacea purpurea l. was used instead of synthetic antioxidants in cake then, antioxidant a...

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...

I investigated reproduction in a three-year study of Echinacea angustifolia, purple coneflower, growing in a fragmented prairie landscape. I quantified the local abundance of flowering conspecifics at individual-based spatial scales and at a population-based spatial scale. Regression analyses revealed that pollen limitation increased while seed set and fecundity decreased with isolation of indi...
