“…Their composition, however, depends on the solvents and technics employed. For example, a study by Babaeva et al reported that a larger quantity of inulin had been extracted by infusion with 40% ethanol (0.70%) than with 70% ethanol (0.51%) [20]. Our research findings agree with this statement.…”

“…Our research findings agree with this statement. The most likely explanation is that 70% ethanol precipitated more of the inulins in the plant matrix contrary to 40% ethanol, and thus the concentration of inulin in 70% ethanolic extract was lower [20]. The same pattern was followed by protein and uronic acid constituents present in the extracts.…”

Phytochemical Characterization of Purple Coneflower Roots (Echinacea purpurea (L.) Moench.) and Their Extracts

Echinacea purpurea is a perennial plant that belongs to the Asteraceae family. It has a wide range of applications mainly in the treatment and prevention of inflammations in the respiratory system. The current study aimed to perform a phytochemical characterization of purple coneflower (Echinacea purpurea) roots and their extracts (water, 40%, 50%, 60% ethanol, and 60% glycerol). Phytochemical characterization was carried out by gravimetric, spectrophotometric, and chromatographic methods. Echinacea roots were characterized by a low lipid (0.8%) content. In contrast, carbohydrates (45%) and proteins (20%) occupied a large part of the dry matter. Amongst the extracts, the highest yield was obtained using water as a solvent (53%). Water extract was rich in protein and carbohydrates as fructans (inulin) were the most abundant carbohydrate constituent. The most exhaustive recovery of the phenolic components was conducted by extraction with 40% ethanol and 60% glycerol. It was found that water is the most suitable extractant for obtaining a polysaccharide-containing complex (PSC) (8.87%). PSC was composed mainly of fructans (inulin) and proteins with different molecular weight distributions. The yield of PSC decreased with an increasing ethanol concentration (40% > 50% > 60%) but the lowest yield was obtained from 60% glycerol extract. The obtained results showed that Echinacea roots contained a large amount of biologically active substances—phenolic components and polysaccharides and that glycerol was equally efficient to ethanol in extracting caffeic acid derivatives from purple coneflower roots. The data can be used for the preparation of extracts having different compositions and thus easily be incorporated into commercial products.

“…They also found a tenfold lower fructan content in preparations based on the above-ground material compared to preparations based on root material. More recent studies also highlighted the presence of fructans in Echinacea preparations and found that the amount of ethanol used for extraction determines the fructan content of the extract [16,115]. As higher DP fructans are not soluble in ethanol, higher ethanol concentrations prevent the extraction of higher DP fructans while favoring a lower average DP.…”

Fructans as Immunomodulatory and Antiviral Agents: The Case of Echinacea

et al. 2019

Throughout history, medicinal purposes of plants have been studied, documented, and acknowledged as an integral part of human healthcare systems. The development of modern medicine still relies largely on this historical knowledge of the use and preparation of plants and their extracts. Further research into the human microbiome highlights the interaction between immunomodulatory responses and plant-derived, prebiotic compounds. One such group of compounds includes the inulin-type fructans (ITFs), which may also act as signaling molecules and antioxidants. These multifunctional compounds occur in a small proportion of plants, many of which have recognized medicinal properties. Echinacea is a well-known medicinal plant and products derived from it are sold globally for its cold-and flu-preventative and general health-promoting properties. Despite the well-documented phytochemical profile of Echinacea plants and products, little research has looked into the possible role of ITFs in these products. This review aims to highlight the occurrence of ITFs in Echinacea derived formulations and the potential role they play in immunomodulation.
