Tolerance To Salinity

The flower industry depends on oil and fragrance, which is addressed in the current work. Different concentrations of NaCl (0, 250, 500, 1000, and 1500 ppm) were applied to Taif rose plants (Rosa damascena var. trigintipetala Dieck) to evaluate their effects on growth and essential oil content. Results clearly indicated the highest survival percentage (98.3%) was seen in untreated plants compared to plants under salinity stress. Moreover, increasing the NaCl levels induced an adverse effect on the growth parameters of Taif rose plants, while some essential oil contents were increased to the maximum degree of their tolerance to salinity stress. The extracted essential oils were analyzed using GC/MS. The essential oils of Taif rose plants treated with 500 ppm NaCl recorded the highest values of citronellol, geraniol and phenylethyl alcohol contents (16.56, 8.67 and 9.87%), respectively. NaCl at 250 ppm produced the highest values of heneicosane (13.12%), and then decreased to the lowest value (7.79%) with the increase of NaCl to 1500 NaCl, compared to the control and other NaCl levels. The current results could highlight the impact of salinity stress on Rosa damascena Miller var. trigintipetala Dieck for better economic and industrial applications.

Abstract Background Essential oil of Rosa × damascena Herrm. is one of the most valuable and important raw materials for the flavor and fragrance industry. The cultivation of this plant has ancient origins, and Kashan was one of the first mountainous regions of Iran dealing with the cultivation of R. × damascena. In this study, both chemical composition and antimicrobial activity of different rose essential oils obtained from five mountainous areas of Kashan region (Maragh, Qamsar, Sadeh, Javinan, and Kamoo) has been investigated along with the influence of the environmental conditions on these properties. Results Results showed that yield and chemical composition of essential oils obtained from Rosa × damascena were significantly affected by the collection area. In particular, the yield of oils varied from ~0.08 to ~0.132% and citronellol (36.70-9.18%), geraniol (12.82-0.47%), nonadecane (22.73-10.36%), heneicosane (31.7-11.43%), and 1-nonadecene (6.03-3.93%) have been detected as main compounds in all the plants collected, but at different concentrations depending on the collection area. The best fragrance and the highest yield were found in the oil from Kamoo area. Similarly to the chemical composition, the antimicrobial activity of the essential oils was affected by their origin, and essential oil obtained from plants collected from Kamoo area disclosed the highest antibacterial and antifungal efficacy. Its inhibition halos were 17.33±0.58 mm against Aspergillus brasiliensis, 15.67±0.58 mm against Staphylococcus aureus, and 12.33±0. 58 mm against Streptococcus pyogenes. Essential oils of R. damascena were also effective against Gram-negative Pseudomonas aeruginosa and they had a MIC value of 62.50 μg/mL irrespective of the collection area (except the oil from Javinan area). On the contrary, the highest antifungal power against Candida albicans yeast was reached using the essential oil obtained from plants collected in Javinan region (MIC and MBC ~62.50 μg/mL). Conclusions Overall results underline the influence of environmental conditions of the different areas of Kashan region, on the chemical composition of and antimicrobial activity of the essential oils of Rosa × damascena. In addition, results disclosed that Kamoo seemed to be the most suitable area for the competitive cultivation of R. × damascena to the intensive production of aromatic flower oil and natural antimicrobial essential oils.

Inflammation of the lower urinary tract is a very common problem, which occurs particularly in women. A concept of a biotextronics system for preventive and support treatment of lower urinary tract inflammations was presented. The system includes a non-woven viscose insert for essential oils application. The oils were deposited on the non-woven viscose and incubated in the temperature of 37 °C and served a model for their action in the vapor phase as the element of the biotextronics system. The essential oils used in the research were the following: chamomile (Matricaria chamomilla L.), sage (Salvia officinalis L. and Salvia lavandulaefolia), juniper (Juniperus communis L.), thyme (Thymus vulgaris L.), and mixtures of chamomile oil with oils of each sage species in a 1:1 ratio. The oils were tested against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus epidermidis, Staphylococcus saprophyticus, and Enterococcus faecalis. The best inhibitory effect in vapor phase was noted for chamomile essential oil at the lowest concentration (0.054 µL/cm3). Both mixtures of chamomile and sage acted antagonistically, lowering the antibacterial activity of the individual oils applied solely. Juniper and Salvia officinalis essential oils at the concentrations tested increased the growth of at least one of the bacteria tested. Salvia lavandulaefolia Vahl. essential oil inhibited all bacteria, only at the concentration 0.214 µL/cm3. The thyme oil, at the concentration 0.054 µL/cm3, reduced the growth of all bacterial species tested. Chamomile and thyme essential oils were chosen for further research in the biotextronics pantiliner system.

Antibacterial And Antioxidant Activity

In recent years, a concern has been expressed about the impact of antibiotics and synthetic antioxidants, which are used to inhibit microbial growth and retard fat oxidation in foods. In addition, antibiotic resistance presents a serious menace to human and environmental ecosystems. This has led the food industry to use natural resources such as essential oils in the preparation of foods, this forming their sensory profile and increasing preservation time there. The objective of this work is to determine the chemical composition and evaluate the antibacterial and antioxidant activity of the essential oil of Illicium verum. The yield of essential oil extracted by hydro distillation is about 4.13%. The chemical composition of the essential oil extracted from the dried fruits of Illicium verum was studied by gas chromatography coupled with mass spectrometry (GC and GC/MS). Twenty-eight constituents, representing 99.74% of the essential oil were identified. The major compounds are: trans-anethole (83.46%), D-Limonene (4.56%), Estragole (3.47%) and Linalool (1.07%). Antioxidant activity was determined by the DPPH assay. The essential oils of Illicium verum showed low antioxidant activity with IC50= 286.19 ± 7.4 mg/mL, compared to Ascorbic acid IC50= 0.09 ± 0.01 mg/mL. The antibacterial effect of this essential oil was tested against six microorganisms, of which Staphylococcus aureus is the most sensitive with an MIC of about 1/1000 (v/v), followed by Staphylococcus epidermidis and Enterobacter cloacae with an MIC equal to 1/100 (v/v).

Sweet basil is an important medicinal plant belonging to Lamiaceae family. In this plant, Phenylpropanoid pathway possesses some enzymes involving in generating suitable essential oil constituents. The main purpose of conducting this study was to investigate the effects of chitosan on sweet basil’s growth and physiological parameters as well as gene expression subjected to salinity stress. After employing a foliar-spray of chitosan at 0 (as control) and 0.2 gl–1, the plants were subjected to salinity treatments at 0, 25, 50, 100, and 150 mM NaCl. The results of this research revealed that chitosan, compared to the controls, improved growth parameters under stressed or non-stressed conditions. In this regard, chitosan increased protein and chlorophyll contents as well as the expression of PAL and COVMT genes leading to an increase in phenolic compounds. To sum up, chitosan improved sweet basil tolerance to salinity through influencing the genes involved in the pathway of phenylpropanoid so as to produce secondary metabolites.

Head Blight

Fusarium head blight caused by Fusarium oxysporum f. sp. Radicis-lycopersici (FORL) is a constraint to tomato cultivation in Korhogo, Côte dIvoire. To control this disease, the antifungal activity of essential oils extracted from certain plants was evaluated in comparison with that of a synthetic fungicide for use. In vitro tests were performed on the different life stages of FORL. The in vivo evaluations consisted in carrying out two modes of treatment (curative and preventive) on plants of a susceptible variety of tomato inoculated with FORL. The results showed that the essential oils significantly reduced the different life stages of F.oxysporum f. sp. Radicis-lycopersici (FORL) as did the synthetic product. Thus, the essential oil Cymbopogon citratus at concentrations of 4000 and 6000 ppm strongly inhibited in vitro the different stages of FORL. In preventive and curative treatment, the essential oils not only improved the growth parameters of tomato plants but also reduced the incidence and severity of diseases. Thus, it was found that Cymbopogon citratus (4000 ppm) in preventive treatment, and Banko plus (250 ppm) in curative treatment reduced the mortality rate of FORL up to 6.66% and improved the growth parameters and reduced the flowering time of the tomato plant.The essential oil of C. citratus could be used for biological control of F. oxysporum f. sp. Radicis lycopersici.

This study focused, for the first time, on the evaluation of the seasonal effect on the chemical composition and biological activities of essential oils hydrodistillated from leaves, trunk bark and fruits of Zanthoxylum leprieurii (Z. leprieurii), a traditional medicinal wild plant growing in Côte d’Ivoire. The essential oils were obtained by hydrodistillation from fresh organs of Z. leprieurii growing on the same site over several months using a Clevenger-type apparatus and analyzed by gas chromatography-mass spectrometry (GC/MS). Leaf essential oils were dominated by tridecan-2-one (9.00 ± 0.02–36.80 ± 0.06%), (E)-β-ocimene (1.30 ± 0.50–23.57 ± 0.47%), β-caryophyllene (7.00 ± 1.02–19.85 ± 0.48%), dendrolasin (1.79 ± 0.08–16.40 ± 0.85%) and undecan-2-one (1.20 ± 0.03–8.51 ± 0.35%). Fruit essential oils were rich in β-myrcene (16.40 ± 0.91–48.27 ± 0.26%), citronellol (1.90 ± 0.02–28.24 ± 0.10%) and geranial (5.30 ± 0.53–12.50 ± 0.47%). Tridecan-2-one (45.26 ± 0.96–78.80 ± 0.55%), β-caryophyllene (1.80 ± 0.23–13.20 ± 0.33%), α-humulene (4.30 ± 1.09–12.73 ± 1.41%) and tridecan-2-ol (2.23 ± 0.17–10.10 ± 0.61%) were identified as major components of trunk bark oils. Statistical analyses of essential oil compositions showed that the variability mainly comes from the organs. Indeed, principal component analysis (PCA) and hierarchical cluster analysis (HCA) allowed us to cluster the samples into three groups, each one consisting of one different Z. leprieurii organ, showing that essential oils hydrodistillated from the different organs do not display the same chemical composition. However, significant differences in essential oil compositions for the same organ were highlighted during the studied period, showing the impact of the seasonal effect on essential oil compositions. Biological activities of the produced essential oils were also investigated. Essential oils exhibited high insecticidal activities against Sitophilus granarius, as well as antioxidant, anti-inflammatory and moderate anti-plasmodial properties.

Previous studies revealed the impact growing location has on the quantity and quality of essential oils derived from numerous Citrus spp., except on the kaffir lime. This study aims to analyze the relationship shared by agroclimatic variables and soil-plant nutrient status to kaffir lime leaves essential oil yield and main composition. The experiment was conducted between February and April 2019 in four growing locations, namely Bogor (6°36′36″ S, 106°46′47″ E), West Bandung (6°48′12″ S, 107°39′16″ E), Pasuruan (7°45′5″ S, 112°40′6″ E) and Tulungagung (8°6′27″ S, 112°0′35″ E). The highest essential oil yield was obtained from Bogor (1.5%), while the lowest one was from Tulungagung (0.78%). The yield was positively and significantly correlated with the rainfall, soil organic carbon, soil pH, and macronutrient levels, i.e., nitrogen, phosphorus, and magnesium. Citronellal, the major component in metabolites’ profile of kaffir lime leaves essential oils, was significantly affected by the growing location. The absolute content of citronellal was positively and significantly correlated with the actual soil pH and leaf Ca content; furthermore, it negatively correlated with the leaf content of Fe, Mn, Zn, Cu. Pearson correlation analysis also showed (i) a negative significant correlation between the relative percentage of citronellol and annual rainfall intensity; (ii) a negative significant correlation between altitude and relative percentage of caryophyllene, and (iii) a positive significant correlation between the relative percentage of linalool and leaf K content.

Capillary barriers (CBs) as engineered porous composites is novel and promising technology for mitigating salinity and drought stress of plants. This study aimed to imitate a naturally formed CB structure recently discovered in the reservoir bed of Al-Khoud dam at the Governorate of Muscat in northern Oman and to test the impact of this unique CB on mitigating the salinity stress of marigold plants grown under an open field condition. A plot was constructed and divided into “structured” (engineered cascade CB design) and “unstructured” soils and planted with marigold (Tagetes erecta) plants that were subjected to four salinity treatments (control with ECi ≈ 0.6 dS m-1 ; 3 dS m-1; 6 dS m-1; and 9 dS m-1). Plant physiological, vegetative, and reproductive growth parameters were measured in each treatment. The results showed that the structured soil significantly saved irrigation water and reduce salts accumulation. Structured soil improved all vegetative and reproductive plant parameters measured and helped in reducing the effects of salinity stress on the growth and production of the marigold under arid-climate field conditions. The results also showed the capability of structured soil in water saving and improving water use efficiency. This study substantiates a novel method in mitigating salinity problem and in water saving in arid and semi-arid regions, in particular in Oman. Further studies are required to test the use of the engineered cascade CB design with different crops and with alternative (e.g. subsurface) irrigation methods.

BACKGROUND: Depression is a serious public health problem. The impact of depression is enormous, ranging from decreasing work productivity, interpersonal disorders, sleep and eating disorders, susceptible to disease to an increase in suicides. In a state of depression, there was an increase in cortisol and changes in the neurotransmitter of the brain monoamine, norepinephrine and dopamine and specifically serotonin level. Treatment of depression using synthetic drugs such as the Selective Serotonin Reuptake Inhibitor (SSRI) drug which is said to be safe turns out to still have side effects, such as stomach disorders, erectile disorders, weight gain and sometimes sleep disorders. So, the usage of traditional medicines can be an alternative. One of the traditional medicines that have been studied in Indonesia was the essential oil of basil leaves, which is known to function as an antidepressant at a dose of 2.5 x 10-2 mL/kg b.w. AIM: To determine the comparison of cortisol and serotonin level between depressed mice which get basil leaf essential oil as intervention, depression mice, and normal mice. METHODS: This research was an experimental type purely using experimental animal models, with an experimental research design Post Test Only Context Group Design in mice (Mus musculus), by dividing 3 groups of mice, namely depressed mice which received essential oil of basil leaves dose of 2.5 x 10-2 mL/kg BW, depression mice, and normal mice, to compare the level of blood cortisol and serotonin while to determine effect of administration basil leaves essential oils in depression mice. RESULTS: Cortisol levels between intervened depression mice, depression mice, and normal mice groups were significantly comparable with p < 0.001, while serotonin level was significantly comparable between intervened depression mice, depression mice, and normal mice group with p < 0.001. CONCLUSION: Evidenced by differences in cortisol levels, serotonin levels between normal mice groups, depressed mice and mice that received essential oils of basil leaves. The comparisons showed that the cortisol level of the intervened depression group was lower than the depression mice group; however the level didn’t reach the level of cortisol in the normal group. While the serotonin level of intervened depression mice group was higher than the depression mice group or normal mice group.
