“…Anethole was the dominant component (>70%) in the EOs of Fhf and Fhu. Estragole and anethole have also been reported as the main components in the EOs of fennel fruit; their average composition was 34.90 and 56.81%, respectively [35]. Agf EOs contained the highest levels of limonene (50.19%) and carvone (42.41%).…”

Fennel and dill are widely used as food additives owing to their various biological activities, such as antioxidants, antimicrobials, food-preservatives, and seasoning capacities. Herein, the nutritional composition and essential oil (EO) chemical profiles of fruits, umbels, stalks, and roots from one dill and two fennel cultivars were evaluated. The fruits had the highest content of crude protein (≥ 15%), crude fat (≥ 8%), and phosphorus (≥ 0.5%), and exhibited the highest total energy (≥ 20 MJ/kg) and EO yield (≥ 2%). Moreover, estragole (86.56% in Fdf), anethole (71.17% in Fhf), fenchone (16.74% in Fhf), limonene (50.19% in Agf), and carvone (42.41% in Agf) were the main components of the EOs generated from the fruits. The chemical profiles of EOs in the roots were significantly different from those of the aerial parts of the fennel and dill; thus, the roots and aerial parts could be distinguished based on myristicin (Variable Importance in Projection (VIP) = 1.90399) and apiol (VIP = 1.85922). The EO components of the aerial parts varied remarkably, and the chemical markers for differentiating these three cultivars were anethole (VIP = 1.36571), estragole (VIP = 1.30292), and carvone (VIP = 1.11947). Overall, our results provide a noteworthy chemical basis for further development of fennel and dill, especially as food additives.

“…A number of studies have documented that the foliar application of licorice and/or Moringa extract has had an enhancement impact on oil production. On Coriandrum sativum (Abd-ElKafie et al, 2016) on dill (Hamad et al, 2017) and on caraway (Massoud et al, 2019), as well as on fennel (El-Serafy and El-Sheshtawy, 2020).…”

Two field experiments were conducted in 2018/2019 and 2019/2020 cropping season, at the Experimental Farm of Heliopolis Univ., El-Sharqea Governorate, Egypt, in cooperation with the Department of Horticulture, Faculty of Agriculture, Benha University to study the influence of licorice aqueous extract at 0, 10, 20, and 40 g/l concentrations and Moringa ethanol extract at 0, 50, and 100 g/l concentrations and their interaction on essential oil content, essential oil composition, and chemical constituents of ajwain (Trachyspermum ammi) under sandy soil conditions, in a split plots design of 12 treatments with three replications for each treatment. The main plots were the concentrations of licorice aqueous extract, the subplots were the concentrations of Moringa ethanol extract. The results demonstrated that treating ajwain plants by spraying with the licorice aqueous extract at 40 g/l and Moringa ethanol extract at 100 g/l (L3 × M2) scored the highest values of the essential oil percent, oil yield/plant, and oil yield/fed. The same treatment (L3 × M2) was recorded the greatest values of the content of the pigment (chlorophyll a, b, total chlorophyll, and carotenoid), also treating ajwain plants by the same treatment was given the highest carbohydrate in the two seasons. However, ajwain plants sprayed with licorice aqueous extract at 0.0 g/l or Moringa ethanol extract at 0.0 g/l (L0 × M0) lead to the lowest values of all the above-mentioned traits. In general, the main chemical constituents of ajwain essential oil were γ-terpinene, followed by thymol and p-cymene, along with α-and β-pinenes, αthujene, myrcene, and Limonene.

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
