Abstract Medicinal plants represent a valuable commodity due to beneficial effects of their natural products on human health, prompting need for finding way optimize/increase production. In this study, novel growing media with various perlite particle size and its mixture peat moss was tested hydroponic-based production Echinacea purpurea medicinal plant under greenhouse conditions. The growth ...

Background & Aim: Hydroxycinnamic acids are one of the most important bioactive substances of Echinacea drugs. These compounds possess immuno-enhancing activity and thus, total hydroxycinnamic acids are mostly used as the main criterion for quality control of Echinacea purpurea and its drugs.  Hence, the quality control of Echinacea requires to develo...

plant secondary materials play an important role in health and human nutrition. according to the importance of coneflower in the production of secondary materials and also the effect of nutrient on the amount of secondary materials, a pot experiment was conducted with a completely randomized design six treatments and three replications in sari university of agricultural sciences and natural res...

background: purple coneflower (echinacea purpurea l.) is one of the most important medicinal plants. hairy root culture of echinace, represent a valuable alternative to field cultivation for the production of bioactive secondary metabolites. objective: the present study investigates the effects of kno3, cacl2 and mgso4 concentrations on growth and the biosynthesis of cichoric acid in echinacea ...

Pollen limitation of plant reproduction occurs in many plant species, particularly those in fragmented habitat; however, causes of pollen limitation are often unknown. We investigated the relationship between pollen limitation and pollinator visitation in the purple coneflower, Echinacea angustifolia (Asteraceae), which grows in the extremely fragmented tall grass prairie of North America. Prev...
