“…All samples (Q1–Q21) analyzed in this study showed different chemical compositions. One of the variables that most influences the chemical composition of the EO is type of soil [ 14 ]. The concentration percentage of the (E)-methyl cinnamate compound had a statistically significant difference ( p -value < 0.5) across the samples from different soil types and the percentage of trans-Caryophyllene did not present a significant difference in all samples ( p -value > 0.5).…”

Ocotea quixos (Lam.) Kosterm. is an aromatic tree native to Ecuador, whose leaves are used to prepare aromatic beverages to which different health benefits are attributed. In this study, Ocotea quixos leaves were collected in the Amazon region in different environmental conditions and subjected to hydrodistillation to isolate the essential oil. The collection variables used were type of soil, amount of shade, and height; in addition, the presence of twig and leaf age and moisture were used as variables. Chemical composition was analyzed by means of gas chromatography equipped with a flame ionization detector and gas chromatography coupled to mass spectrometry. A wide variety of chemical compositions were detected in the samples. In total, forty-seven compounds were identified, which represented between 97.17% and 99.89% of the total composition. The constituents were mainly grouped into aliphatic sesquiterpene hydrocarbons (33.03–55.89%), other compounds (8.94–47.83%), and oxygenated monoterpenes (1.97–39.66%). The main constituents were found to be (E)-cinnamyl acetate (5.96–41.65%), (E)-methyl cinnamate (0.38–37.91%), and trans-caryophyllene (8.77–37.02%). The statistical analysis suggested the existence of two essential oil chemotypes and a direct correlation between environmental conditions and chemical composition of the essential oils.

“…The physical and chemical properties of soil are one of the most determinants factors in various secondary products and could be involved in the EO composition in different species of aromatic plants (Melito et al 2013;Rapposelli et al 2015). Also, previous studies indicated that EO-bearing plants differ with various soil properties and the production of EO requires suitable soil for greater yield and better quality (Khalid et al 2020a).…”

Grapefruit and shaddock essential oils (EOs) have remarkable biological activities. Soil types are characterized by various properties which affect the essential oils of grapefruit and shaddock. Many Citrus species are cultivated in the Nile Valley of Egypt, which is characterized by its clay soil, but there are no large areas cultivated with both grapefruit and shaddock. The reclaimed desert in Egypt which characterized by sand soil is expanded by planting many Citrus species, which produce different residues such as leaves, flowers, and peels rich in essential oil, which is used in the production of natural raw materials as a source for medicine and food. Thus, the variations of grapefruit and shaddock essential oils and their constituents were evaluated under sand and clay soils to find out the extent of the opportunities for expanding their cultivation in the new reclamation region as a natural source of EO. The leaves, flower, and peel EOs of grapefruit and shaddock were isolated by hydro-distillation and analyzed by gas chromatography and gas chromatography/mass spectrometry; data were statistically analyzed by one-way analysis of variance. Samples collected from trees grown in sand soil produced the greatest amounts of essential oil in both species whatever the organ from which this oil was extracted. Limonene was of the major compound in both peel and flower grapefruit essential oils, while sabinene was the predominant one in leaves EO (39.8% and 44.8%, in clay and sand soils respectively). E-phytol, linalool, and limonene were the predominant constituent in leaves, flower, and peel of shaddock essential oil, respectively. Various identified constituents in leaves, flowers, and peels noteworthy the presence of oxygenated diterpenes in percentage not less than 33% in leaves shaddock essential oil which was completely omitted in the other organs and in the grapefruit EOs. The monoterpene hydrocarbon was the major chemical class in various essential oils of grapefruit; oxygenated diterpenes, oxygenated monoterpenes, and monoterpene hydrocarbon were the main chemical classes of leaves, flower, and peel essential oils from shaddock, respectively. In the essential oil contents (%), most of the main constituents and major chemical groups were higher under sand soil than clay soil. This study serves as a reference for selection the suitable soil to produce the essential oil according to the components of interest; also, this trial recommends the cultivation of both species in reclaimed sand soil of Egypt.

“…Also, different chemotypes have been described for a number of medicinal plants [26][27][28][29]. Moreover, studies have shown that the different characteristics of medicinal plant may be affected by a variety of ecological factors such soil composition, temperature, humidity and other climatic conditions [30][31][32][33]. Consequently, these changes in content and composition would definitely affect the pharmacological activity of the essential oil.…”

Background: Several agricultural or environmental factors affect plants' chemical and pharmacological properties.Methods: In this study, the essential oil of Libyan Satureja thymbra was isolated from plants collected during two successive years at two different altitudes; Wasita (WEO) and Safsaf (SEO), 156 and 661 m above sea level, respectively. Results: GC/MS allowed the identification of 21 and 23 compounds, respectively. Thymol prevailed in WEO (26.69%), while carvacrol prevailed in SEO (14.30%). Antimicrobial activity was tested by agar-well diffusion method, and MIC/ MLC values were determined by broth dilution method. Values of MIC/MLC were 0.125/0.25 μg/ml for SEO against S. aureus, P. mirabilis and K. pneumonia and for WEO against B. subtilus. It was observed that plants growing at lower altitude in Wasita locality had better antifungal activity, while those growing at higher altitude at Safsaf locality had better antibacterial activity. Both essential oils had a better anthelmintic activity than the standard piperazine citrate against a tested earthworm. However, SEO oil had a significantly higher anthelmintic activity than WEO. Cytotoxicity of the oils tested using SRB assay on human breast cancer (MCF-7) and colon cancer cell lines (HCT-116) showed better activity for SEO, especially against HCT-116 with IC 50 2.45 ± 0.21 μg/ml. Conclusions: Thus, altitude is an important factor that should be considered as it affected the yield, composition and biology of the plant extracts.
