echinacea tennesseensis/carbohydrate

Pressed juices from Echinacea purpurea are used as non-specific immunostimulants, and arabinogalactan-proteins (AGPs) are part of the active principle. An AGP fraction was isolated from pressed juice of E. purpurea by precipitation with ss-glucosyl Yariv reagent, followed by gel-permeation

OBJECTIVE In spite of the impressive species diversity in the Asteraceae and their widespread appeal to many generalist pollinators, floral-nectary ultrastructure in the family has rarely been investigated. To redress this, a study using Echinacea purpurea, a plant of horticultural and nutraceutical

Echinacea purpurea has a long history in traditional medicine. To verify the pharmacological efficacy of active principles, a polysaccharide-phenolic-protein complex has been isolated from flowering parts of herb by alkaline extraction. It showed on GPC and HPLC one peak of molecular mass around 10

Pressed juices of the aerial parts of Echinacea purpurea are used as non-specific immunostimulants, and arabinogalactan-proteins (AGPs) have been shown to be part of the active principle. Monoclonal antibodies against an AGP from pressed juice of Echinacea purpurea with complement-stimulating

Polyploidization is an effective means of improving the active components and quality of secondary metabolism in medicinal plants. In the present study, we compared the immunostimulatory effects of crude polysaccharides from tetraploid and diploid Echinacea purpurea. The results showed that the

BACKGROUND Echinacea purpurea (L.) Moench is one of the mostly used herbs in the traditional medicine for the treatment of respiratory diseases. Modern interest in Echinacea is directed to its immunomodulatory activity. Recent studies have shown that secretion of asthma-related cytokines in the

Echinacea purpurea (L.) Moench (EP) is a well-studied plant used for health benefits. Even though there are a lot of data on EP secondary metabolites, its active proteins are not studied well enough. The aim of our experiment was to purify lectin fraction from EP roots and evaluate its
