Essential oils (EOs) are volatile, natural, complex compounds characterized by a strong odour and are formed by aromatic plants as secondary metabolites. The essential oil of Lavendula officinalis was extracted using hydrodistillation process. Hydro-Distillation is potentially a very useful method to extract essential oil from various plants and from their different parts. The principle of extraction is based on the isotropic distillation. The yield is dependent on various parameters like weight of raw material, volume of water, size of raw material and nature of raw material. Samples from aerial parts of three Lavendula ecotypes were analyzed for essential oil content to find out as to which ecotype excels in oil content and which ecotype gave the minimum essential oil output. Air dried leafy stalks and stems of L. officinalis were taken and submitted to Hydro distillation for 4 hrs using Clevenger type apparatus. Briefly, the samples were immersed in water and heated to boiling, after which the essential oil was evaporated together with water vapour and finally collected in a condenser. The distillates (EOs) were isolated and dried over anhydrous sodium sulphate. The oils were stored in the sealed vials at 2°C for further studies. Each extraction was performed at least three times. The oil content was determined on an oil volume to tissue weight basis. Estimated oil content was lowest in Srinagar ecotype to a highest in Pulwama ecotype. Pulwama ecotype was followed by Budgam ecotype. This could be due to the variation in altitude and location.

Basil is an aromatic, medicinal, culinary, and multifunctional herb which is grown in different parts of Ethiopia. Although the oil distilled from the herb, as well as its herbal yields, are a crucial input in the pharmaceutical industry and for culinary purposes, the yield obtained is below its potential due to various challenges. Genotype and plant spacing are two of the factors which contribute to the low production of the crop. A field trial was conducted at Jimma University College of Agriculture and Veterinary Medicine (JUCAVM) in 2016 and 2017 to assess the effect of genotype and plant spacing on essential oil yield and other yield-related traits of this important herb. Four promising genotypes (BO-1, BO-3, BO-4, and BO-5) and three plant spacings (20, 30, and 40 cm) were studied in a 4 × 3 factorial design arranged as randomized complete blocks (RCBD) with three replications. Data on plant height, leaf area, number of primary branches, essential oil content and oil yield were collected and analyzed. The analysis of variance revealed that there were highly significant (<em>p</em> &lt; 0.01) interaction effect of genotype with plant spacing for all parameters tested. The maximum essential oil yield (7.88 kg ha<sup>−1</sup>) was obtained from genotype BO-5 at 30 cm spacing, whilst the least (2.68 kg ha<sup>−1</sup>) was recorded from BO-1 at 40 cm spacing. The maximum oil content (101 mL g<sup>−1</sup>) was gained from BO-1 at 20 cm, but BO-3 at 30 cm spacing recorded the least oil content though there were no significant differences between the three treatment combinations. Further studies at different locations and seasons will be important to for future local recommendations.

Fresh leaves of N. glauca were collected from the northern region of Tunisia. The leaves were submitted to water distillation for 4 h, using a Clevenger-type apparatus. The obtained essential oils were dried over anhydrous sodium sulphate and after filtration, stored at 4 °C until use. The chemical composition of the isolated essential oil was analyzed by gas chromatography–mass spectrometry (GC–MS). Eighteen compounds were identified: eugenol, the major compound in the essential oil, was present at a high level (58.49%), followed by nonadecane, eugenyl acetate and tridecane, 3-methyl at 6.38; 5.57 and 5.19%, respectively. The percentage of compounds dodecane, 2, 6, 11 trimethyl, tetradecane, docosane, tricosane and 1, 2-benzene dicarboxilic, dibutyl ester varied between 1 and 2%; whereas the other compounds (including limonene, and saturated hydrocarbons) remained at low percentages, not exceeding 1%. This study could be very useful for the characterization, pharmaceutical and therapeutic applications of the essential oil from N. glauca.

Lamiaceae is one of the largest families of aromatic plants and it is characterized by the presence of external glandular structures which produce essential oils highly valued in cosmetics and medicine. Plants of Lavandula latifolia, Mentha piperita, Salvia sclarea, Salvia lavandulifolia, Thymus capitatus, and Thymus mastichina were grown for one year. In order to evaluate the effects of drought stress, plants were subjected to two water treatments (100% ETo and 70% ETo, including the rainfall during the experimental period). At the end of the experiment, the biomass, the essential oil content, and leaf nutrients concentration were assessed for each water treatment and species studied. At the end of the experiment, L. latifolia, M. piperita and T. capitatus plants showed a significant fresh weight reduction under drought stress conditions whereas the other species studied remained unchanged. With respect to dry weight, only L. latifolia plants showed a reduction under water deficit conditions. As far as essential oil content was concerned, L. latifolia and S. sclarea plants had a reduction under water deficit conditions. Leaf nutrient concentration showed different trends between species considering the nutrient assessed. The economic viability of the growth of this species will be dependent on the benefits achieved which are related to yield production obtained and the price accorded for both raw material and the essential oil extracted.

SummaryObjective: Chamomile plants (Chamomilla recutita L. Rausch) are often attacked by pests, which usually cause the decrease of raw material yield and its quality. The objects of field trial were two chamomile cultivars: Złoty Łan (4n) and Promyk (2n) cultivated under organic regime. The aim of this study was to evaluate of impact of the spinosad treatment and its time of application on two chamomile cultivars: cv. Promyk – 2n and cv. Złoty Łan – 4n exposed to insect pests.Methods: The first treatment with spinosad as a preventative control (P) was performed in the early phase of plant development (seven leaves). Intervention (I) treatment was made in green bud phase. In both terms of observation insect pests were observed and collected. In each spraying application of 0.06 g of spinosad per 1 liter of water was used.Results: Spinosad was able to limit the number of pest population and finally increased yielding of the treated cultivars as compared to the untreated plants. Time of spinosad application for cv. Złoty Łan plants was not statistically siginificant, although was more effective for the preventative treatment of cv. Promyk in the increasing of the plant biomass (283.8 g · m−2) and seed (32 g · m−2) yields than intervention.Conclusion: Protection treatment with spinosad might be recommended in chamomile cultivation and it is more effective than intervention in diploid cultivar which begin blooming earlier than tetraploid. Essential oil content was not related with protection treatment for diploid cultivar, although intervention in tetraploid cultivar caused higher content of oil.

Lomatium dissectum (Torrey & Gray) Mathias & Constance, a perennial from the Apiaceae, has been among important traditional medicinal plants of the native North Americans for thousands of years. Preparations from the tuber are used to improve the general well-being, immune system, and adaptation. Its formulations with other herbs is used in cosmetics for skin regeneration, and treatment of psoriasis. L. dissectum is normally collected from the wild for commercial processing. As the demand for the raw material is increasing, there is a growing danger of genetic erosion of the wild species. In addition to this, wild collection does not guarantee regular availability, quality, and exact botanical identity. The objective of this investigation was, therefore, to study the variability in tuber and seed yield, essential oil content, and find effective method of increasing seed germination and develop improved cultivars, suitable for commercial cultivation. We found significant variations in tuber and seed yield/plant, and essential oil content in the tubers. The color of the oil varied from pale green to deep green. The intensity and composition of the aroma of the oil obtained from individual plants was also found to vary significantly. We carried out investigations with microbial seed pretreatment under laboratory and field conditions, with varying concentrations and length of seed soaking. The microbial (RIBAV™) seed pretreatment for 20 min, at a concentration of 20% under laboratory conditions resulted in a 99.2% germination, while control variants had only 18% to 26% seed germination. Pretreated seeds took significantly less time for germination compared to the control. Similar results were recorded for seeds sown under field conditions. Seedlings from pretreated seeds showed vigorous growth and better field establishment, compared to the control variants.
