“…3). These results is consistent with previous finding [15], suggested the important role of soil and irrigation water properties as limiting factors of medicinal plant yield and quality. Aswan governorate characterized the warmest and driest climate according to the weather data, while El-Menya had the coldest and wettest climate.…”

“…Crop production is determined by environmental conditions, which are the main determinant factor of crop success in specific area. The agro-climatic zone and selection of suitable locations could be important strategies for optimizing the yield and quality of medicinal plants [14,15]. On the other hand, irrigation water and mineral nutrition are key resources that can determine plant growth and survival which are affected by various factors, including climate and soil properties [16,17].…”

Objective: Nowadays, one of the growing industries is the herbal drug-based medicaments. This study sought to assess the quality and yield characterizes of black cumin under different locations through Egypt to introduce final analysis information for producers and exporters in Egypt. Methods: This experiment was carried out in seven sites in different locations through Egypt to assess the growth, yield and essential oil content of black cumin plants as following; four sites in El-Minya Governorate, two sites in Bahariya Oasis, and one site in Aswan Governorate. Results: Cultivation locations significantly affected on quality and growth characteristics. The highest seed and fixed oil yields (830 kilogram seeds and 206 kilogram fixed oil) were observed under clay loam soil (Old Land farm), while the lowest yields (500 kilogram seeds and 105 kilogram fixed oil) were observed under sandy soil (El-Nanaaih farm) at El-Menya. The highest content of active substance (Fixed oil %) was observed in clay loam sandy soil of Sekem farm and the lowest in Lena farm with sandy soil at Bahariya Oasis. Neither seed yield nor fixed oil content showed significant correlation with Na+, Cl-, and HCO3--of irrigation water. Although plants cultivated in Wadi El-Nokra at Aswan produced low fixed oil content (18.3%), main components, Linoleic and Oleic acid, were relatively high. Conclusion: The assessment of Nigella sativa under different locations gave evidence of the interactions between weather and soil properties and their impact on the quality and yield of oil of Nigella sativa plants.

“…The highest yield and essential oil content were obtained under even high salinity conditions and sesquiterpene hydrocarbons were more abundant under these salinity conditions. These authors encourage farmers to grow chamomile where saline soils and/or saline irrigation water are present Hendawy et al [40]. The difference between our results and those of Hendawy et al [40] can be explained by the strong importance of the developmental stage of the plants when harvesting and extracting the essential oils.…”

The present study aims to evaluate the antioxidant and antimicrobial activity of essential oils (EO) extracted from safflower plants grown in the absence and presence of NaCl, 50 mM. Plants treated with 50 mM of NaCl showed decreases in root, stem, and leaf dry weight. Results of the essential oils showed that roots have a higher EO yield than leaves and stems. Salinity caused a decrease in this yield in roots and leaves but not in stems. The compounds identified in the EO extracted from these organs belong to seven chemical classes of which the dominant class is the sesquiterpene hydrocarbons. The chemotype of C. tinctorius EO is variable depending on the organ and the treatment. The safflower essential oils showed low antioxidant, antiradical, and iron-reducing activities compared to those of the positive control (BHT). In an antifungal activity test, only two strains, Aspergillus niger and Candida albicans, were found to be highly sensitive to these oils as they showed almost total inhibition of their growth. For antibacterial activity, safflower EOs showed significant antimicrobial activity against Bacillus subtilis, Bacillus cereus, and Xanthomonas campestris in both control and NaCl-treated plants: for these three strains, total inhibition of growth was noted at 50,000 ppm of EO in leaves and roots; whereas for stems, total inhibition was noted only for the third strain (Xanthomonas campestris). For other strains, this inhibition was variable and weak. Salt was found to have no effect on the activities of safflower EOs.

“…The anhydrous sodium sulfate was used to dehydrate the extracted essential oil and was stored in a freezer for further gas chromatography-mass spectrometry (GC-MS) analysis. The chromatographic (GC-MS) analysis was carried out at the Department of Chemistry, Faculty of Science, Aswan University, Aswan, Egypt according to previous study [25]. Major components were identified using the following analytical techniques:…”

This experiment was conducted to examine the influence of drying methods on the essential oil of chamomile (Matricaria chamomilla L.) and its chemical composition. Chamomile flower heads were dried using five different methods: sunlight for 72 h; shade for 1 week; oven at 40 °C for 72 h; solar dryer for 72 h; and microwave for 5 min. Drying methods had slight and nonsignificant impacts on dry biomass of flower heads. The highest percentages of oil in flowers (0.35–0.50%) were observed after solar-drying methods, and the lowest percentage of oil was found after microwave drying (0.24–0.33%). Drying methods significantly influenced the number of identified compounds. The maximum was identified after solar drying (21 compounds), while the lowest was identified after microwave drying (13 compounds), which revealed the solar ability to preserve compounds in contrast to microwave, which crushed the compounds. Major compounds were α-bisabolol oxide A (33.0–50.5%), (Z)-tonghaosu (10.0–18.7%), α-bisabolol oxide B (8.2–15.4%), α-bisabolone oxide A (5.4–14.6%), and chamazulene (1.9–5.2%) of essential oil. Drying methods clearly affected major compounds’ content as the lowest α-bisabolol oxide A was after sun drying, and the lowest α-bisabolol oxide B was after solar drying. (Z)-tonghaosu increased during drying compared to fresh flowers. Solar drying maintained higher chamazulene content (3.0%) compared to other drying methods. The results of this study suggest that drying under the shady conditions preserved chemical composition of essential oil with higher α-bisabolol content compared to other drying methods.
