The goal of this study was to determine whether extracts and isolated alkylamides from Echinacea purpurea would be useful for prevention of the inflammatory response that accompanies infections with H1N1 influenza A. Seventeen extracts and 4 alkylamides were tested for the ability to inhibit production of cytokines, chemokines, and PGE₂ from RAW 264.7 macrophage-like cells infected with the H1N...

Therapeutic or medicinal plants are very beneficial for economic and therapeutic purposes. These plants contain active constituents which are used for the rehabilitation of many human diseases. These constituents are isolated and used against various pathogens[1,2]. Cichorium intybus (C. intybus ) seeds have been successfully used in Ayurvedic and Unani systems of medicine. It is one of the imp...

The aim of this study was to set up and validate an RP-LC method with DAD-detection to quantify caffeic acid derivatives in various Echinacea spp. Samples were extracted with 80% methanol. The analyses were carried out on a Lichrospher RP-18 column (125 mm x 4 mm i.d., 5 microm), with a mobile phase gradient, which increases the acetonitrile level in a phosphoric acid solution (0.1%). The flow ...

Creating high-quality and salt-tolerant plant germplasm is an effective strategy to improve the utilization of saline-alkali land. Salt-induced callus mutation was used create dandelion mutant calluses were obtained under NaCl concentrations 0.8%, 1%, 1.2% with identification random amplified polymorphic DNA (RAPD) markers. A new line, “Binpu 2”, selected from progenies tissue culture plantlets...

Cichoric acid (CA), a plant-based nutraceutical, is extracted from Echinacea purpurea and other edible plants and vegetables and exhibits multiple biological functions, including antioxidant and hypoglycemic effects. The objective of this study was to determine the effect of CA on the energy regulation pathways and the antioxidant response system in insulin resistance and diabetes-induced hepat...
