“…The osmotic pressure in the cell increase by increasing of NO 3 − concentration, leading to sufficient swelling pressure for cell division that affect the morphological properties 14 . Meanwhile, the NO 3 − dosage can influence growing substrate pH, especially in nutrient recirculating systems 18 . It has been found that an increase of NO 3 − dosage caused a significant increase of medicinal and phytochemical compounds of E. purpurea due to improve of rhizomata cum radicibus growth 31 .…”

“…There are some reports showing that stress conditions increase either phenylalanine ammonia lyase (PAL) synthesis or activity in plants 6,11,12,14,32 ; other authors 24 have found that some stress treatments delay the increase in wound-induced PAL activity. Phenylalanine Ammonia-Lyase activity was found to vary greatly with the stage of plant development 18 . The results were in accommodation with Zaushintsena et al (2019).…”

“…For instance, the main phenolic compounds of E. purpurea were found as caffeic acid esters and chicoric acid, as well as, polysaccarides was dominant in E. purpurea rhizomata cum radicibus extracts 17 . Recent studies demonstrated that the polysaccharide content leads to enhance the macrophage activity and the cytokine production 18 . Also, the antifungal and antiviral properties of E. purpurea were related to certain groups of the phenolic compounds and alkamides 18 – 20 .…”

Medicinal plant production is most important than other agricultural plants due to their phytochemical compounds effects on human health. Paying attention to plant nutrition requirement is so important. In order to assess the effect of nitrate (NO 3 −) dosage supplies from two types of fertilizers on growth and phytochemical properties of Echinacea purpurea rhizomata cum radicibus, an experiment with completely simple design was carried out under greenhouse conditions. two types of fertilizers (new invented nitrogen (N) slow release fertilizer and urea chemical fertilizer) at three dosages (50, 100, and 150 mM) were applied. Plant growth parameters and total phenolic (TPC), total flavonoids (TFC), polysaccarides content, essential oil content, caffeic acid derivatives, and anti-radical scavenging activities of E. purpurea were assessed. The results showed the significant (p ≤ 0.01) differences among treatments, both in growth and phytochemical properties. Using of n slow release, especially in 150 mM dosage, significantly increased all the plant growth and phytochemical properties. The dried E. purpurea rhizomata cum radicibus contained more caftaric acid (max 12.56 mg g −1 DW) and chicoric acid (max 7.56 mg g −1 DW) than other derivatives. Despite the impact of heavy metals on yield and growth of E. purpurea, the concentration of all heavy metals and micronutrients (boron (B), cadmium (cd), copper (cu), iron (fe), manganese (Mn), molybdenum (Mo), nickel (ni), lead (pb), and zinc (Zn)) in studied soil and fertilizer samples was less than United States environmental protection Agency (USepA) limits of contamination. Based on the results, using of n slow release fertilizers can improve phytochemical properties of the plant due to its polymeric structure and can be a suitable substitution of chemical fertilizers, especially in medicinal plants growth. Many of researchers are pay attention to herbal and medicinal plants as natural remedies due to their bioactive compounds recently 1,2. Echinacea purpurea (L.) Moench is one of the most important medical plants of Asteraceae family with various pharmacological effects 3. The major three species of Echinacea are known as Echinacea angustifolia, Echinacea purpurea, and Echinacea pallida. E. purpurea is native to much of the United States and its morphological properties are also known as purple coneflower with orange and cone-shaped flowering head that change to purple, rose, or white petals during June to September 4. It has a narrow leaves and three feet height stem with dark, thick and pungent rhizomata cum radicibus 5. In the environment, E. purpurea grows randomically along water canals with low densities for affective harvest for commercial purposes 6. Comparing of other Echinacea species, E. purpurea is the most able species to adjust to new conditions. It is resistance to heat or cold weather conditions, easy to grow, and flaunt high efficiency 7,8. Numerous scientific
