“…The plants were divided into roots, stems, flower heads, and lower and upper leaves after washing with tap water. Root, samples were dried at 25 ± 1 ° C, ground into a fine powder, and collected for phytochemical analysis 26 . Due to the perennial nature of this plant and the flowering of the plant in the second year, economically, flowers are first considered as a medicinal organ and then the root.…”

Medicinal plants are considered as one of the most important sources of chemical compounds, so preparing a suitable culture media for medicinal plant growth is a critical factor. The present study is aimed to improve the caffeic acid derivatives and alkylamides percentages of Echinacea purpurea root extract in hydroponic culture media with different perlite particle size and NO3−/NH4+ ratios. Perlite particle size in the growing media was varied as very coarse perlite (more than 2 mm), coarse perlite (1.5–2 mm), medium perlite (1–1.5 mm), fine perlite (0.5–1 mm), and very fine perlite (less than 0.5 mm) in different ratios to peat moss (including pure perlite, 50:50 v/v, 30:70 v/v, and pure peat moss). Two NO3−/NH4+ ratios (90:10 and 70:30) were tested in each growing media. All phytochemical analyses were performed according to standard methods using high performance liquid chromatography (HPLC). It was found that the E. purpurea grown in the medium containing very fine-grade perlite with 50:50 v/v perlite to peat moss ratio had the maximum caffeic acid derivatives, including chicoric acid (17 mg g−1 DW), caftaric acid (6.3 mg g−1 DW), chlorogenic acid (0.93 mg g−1 DW), cynarin (0.84 mg g−1 DW), and echinacoside (0.73 mg g−1 DW), as well as, alkylamides (54.21%). The percentages of these phytochemical compounds increased by decreasing perlite particle size and increasing of NO3−/NH4+ ratio. The major alkylamide in the E. purpurea root extract was dodeca-2E, 4E, 8Z-10 (E/Z)-tetraenoic acid isobutylamide in all treatments, ranging from 31.12 to 54.21% of total dry weight. It can be concluded that optimizing hydroponic culture media and nutrient solution has significant effects on E. purpurea chemical compounds.

Medicinal plants are considered as one of the most important sources of chemical compounds, so preparing a suitable culture media for medicinal plant growth is a critical factor. The present study is aimed to improve the caffeic acid derivatives and alkylamides percentages of Echinacea purpurea root extract by optimizing the NO3-/NH4 + ratio in new hydroponic culture media. Perlite particle size in the growing media was varied as very coarse perlite (more than 2 mm), coarse perlite (1.5-2 mm), medium perlite (1-1.5 mm), fine perlite (0.5-1 mm), and very fine perlite (less than 0.5 mm) with a mixture of peat moss at 50:50 v/v and 30:70 v/v peat moss to perlite ratios. Two NO3-/NH4 + ratios (90:10 and 70:30) were tested in each growing media. All phytochemical analyses were performed according to standard methods using high performance liquid chromatography (HPLC).

“…Increasing root colonization with the help of biofertilizers helps to improve the phenolic compound of plant roots such as cynarin, cichoric and caftaric acid. [31] Soil fertilization with the biochemical fertilizers such as AMF and Pseudomonas species have improved growth and yield components. [32][33][34][35][36] AMF and PFB were more useful for increasing plant nutrients, improving leaf relative water content and decreased ion leakage.…”

The information regarding the effect of the mycorrhizal inoculation on different Echinacea species is not available in detail. Therefore, here we determined the changes in the biochemical composition of echinacea as a result of mycorrhizal inoculation. This experiment was undertaken to assess the effect of the mycorrhizal association on biochemical properties of different echinacea species (E. angustifolia,E. purpurea, E. pallida). Here various echinacea species were inoculated with mycorrhiza to examine the species richness in different traits. The results established that biological traits (plant dry matter, chlorophyll content, carotenoid, N content, P content, K content) and physiological and mycorrhization characteristics (Root essential oil, ABTS Antioxidant, Ferric-Reducing Antioxidant, Total phenolic, AM Spore No., AM Root Colonization) both are higher under mycorrhizal association than the control plants of different echinacea species. E. purpurea showed greater results than the E. angustifolia and E. pallida. Among biochemical properties chlorophyll content, carotenoid and N, P, K were significantly higher underE. Purpurea than the E. angustifolia and E.pallida. Total dry matter was higher under E. angustifolia (49.23 g) and minimum dry matter was found under E. pallida (40.07 g). Physiological and mycorrhizal traits were significantly higher under E. purpurea than the other species. E. purpurea showed higher AM Spore No., AM Root Colonization 231.30, 78.70% respectively. Lowest physiological and mycorrhization characteristics were found under E. pallida. The result of mycorrhizal association was very effective for plant growth and increased bio-physicochemical properties than the control plants.
