In recent years, it has been shown that biostimulants can efficiently enhance plant metabolic processes, leading to an increased production of essential oil (EO) in aromatic plants. The present study aimed to evaluate the effects of two different commercial biostimulants composed of amino acids and seaweed extract, normally used for food organic crops, on the production and composition of EO and hydrosol of Lavandula x intermedia, cultivar “Grosso”. The products were applied during 2020 growing season on lavender crops in three different locations of the Northern Italian (Emilia-Romagna Region) Apennines. Plants were harvested and EOs extracted by steam distillation and analyzed by gas chromatography. Both biostimulants affected the yield of EO per plant (+11% to +49% depending on the treatment/farm combination) without significantly changing the chemical composition of EOs and hydrosols. Conversely, the composition of EOs and hydrosols are related to the location, and the main compounds of “Grosso” cultivar, limonene, 1,8-cineole, cis-ocimene, linalool, camphor, borneol, terpinen-4-ol, and linalyl acetate, show different ratios at the experimental test sites. The differences might be due to the sunlight exposure and various maintenance of the crops over the years. In conclusion, these results suggest that the employment of biostimulants on lavandin crops do not endanger the quality of the EO while increasing biomass production and promoting the sustainability of the crop.

Essential oil was obtained in a yield 1.1%, w/w, by steam distillation of Elionurus tristis leaves from Madagascar. The chemical composition was analyzed qualitatively and quantitatively by GC-MS and GC-FID, respectively. To the best of our knowledge, this is the first chemical analysis of this essential oil. Seventy-three compounds were identified, corresponding to 94.9% of the total essential oil. The principal compounds were sesquiterpenes and the more represented were β-gurjunene (18.4%), neoclovene (15.8%) and nootkatone (10.4%). Through a comparative study, we observed a large variability between the components of E. tristis essential oil and those from others species of the same genus. Evaluation of the antioxidant (ABTS and DPPH assays) and anti-tuberculosis activities of the essential oil showed weak antioxidant potency but an interesting anti-tuberculosis activity with a MIC of 32 mg/L. This activity prompted us to evaluate individually the major components for the treatment of tuberculosis.

The supercritical fluid extraction (SFE) of clove bud essential oil was studied using CO2 as solvent. The effect of operation conditions was analyzed in a series of experiments at temperatures between 325 and 416 K and pressures between 110 and 190 bar. The collected extracts were analyzed and the relative composition of the essential oil was determined. The optimum condition was found in a temperature of 353 K and at a pressure of 190 bar, minimizing the number of extracts to two compounds (eugenol and eugenyl acetate). The extract obtained from clove bud by using supercritical fluid extraction was compared with the essential oil obtained by steam distillation and microwave-assisted extraction by considering both quantity and quality of the product. The oil yield was higher in steam distillation and microwave oven extraction. In contrast, oil extracted by using SFE contained higher amount of eugenol and eugenyl acetate.

Coriander is an important aromatic plant of India. On steam distillation, the seeds yield a colourless or pale yellow volatile essential oil, which is used for flavouring food products, liqueurs, alcoholic beverages and perfumes. Coriander is also used in the synthesis of vitamin A (Bedoukian, 1967). The Central Institute of Medicinal and Aromatic Plants introduced several Bulgarian selections of coriander and evolved a superior variety, CIMPO S-33. This variety contains more essential oil (about 1·5%) than the local varieties available in India (0·2–0·3%) (Dimri, Khan & Narayana, 1976). Earlier work on coriander has shown that application of N (Bhupinder Singh et al. 1979) and N, P and K (Vagujfalvi, 1964) increases seed and oil yields of coriander. Information on nutrient uptake by coriander and on the effect of fertilizers on coriander oil quality is not available in India. The present experiment was designed to study the effect of different rates of nitrogen, phosphorus and potassium application on seed yield, yield and quality of essential oil and N, P and K uptake by coriander (cv. CIMPO S-33).

Lemongrass essential oil is obtained from the distillation of lemongrass plant. The main content of this oil is sitral content. This study aimed to determine the quality of essential oil produced by the method of water-steam destillation. The experiment was done by water-steam destillation of stalks and leaves of lemongrass, respectively, under 3 repeatations. Lemongrass essential oil obtained from leaves was 0,399%, which is 10-fold greater than the yield of the stalks (0,039%). The specific gravity of Lemongrass essential oil obtained from leaves was 0,8987 where as the specific gravity of Lemongrass essential oil obtained from stalks was 0.8940. The refractive index of lemongrass oil obtained from  leaves was 1.4876 while the refractive index of lemongrass oil obtained from stalks was 1.4880. Based on solubility in 70% alcohol test, lemongrass essential oil obtained from the leaves and stalks were a little bit cloud at a ratio of 1: 5. Based on its yield, it can be concluded that the leave plant produced more oil. However, the quality of both oils showed that lemongrass essential oil met the EAO Standard.

Caraway fruits contain 1–6% of essential oils consisting of about 30 compounds, from which carvone and limonene account form the main portion, about 95%. To evaluate the quality of various caraway cultivars, the amounts of essential oils and the carvone/limonene ratio were measured. The most common method of essential oil evaluation is steam distillation in accordance with Standard ČSN 58 0110, but an alternative method – supercritical fluid extraction (SFE) – was also investigated in this paper. Ground caraway fruits were extracted under different SFE conditions (pressure, temperature, use of modifiers). Released compounds (carvone and limonene) were quantified by GC.

The industrial development of flavor and fragrance currently leads to natural ingredients. Kaffir lime is a potential ingredient developed from Indonesia, but distillation of essential oil in Indonesia generally results in low yields and quality. Fermentation as the initial treatment of distillation would improve the yield and quality of essential oil. The fermentation process is usually performed as pretreatment using cellulolytic bacteria such as Trichoderma harzianum, Trichoderma viride, or Trichoderma reesei, but the use of those bacteria is considered less practical for essential oil distillation process. Therefore, this research utilized tempeh yeast to increase yield and quality of essential oil. Since tempeh yeast consists of Rhizopus producing hyphae, it is expected that hyphae are able to penetrate the tissue, making it easier for oil to get out of the leaves. The aerobic fermentation process was carried out by continuous addition of air inside the fermenter with air compressor. Fermentation was observed within four days. The distillation was performed by using steam distillation method. The result of this study showed that leaf lime essential oil with fermentation process of day 3 produced the highest yield of 0.67%, which increased 20% compared to non-fermented leaves. The composition of leaf lime essential oil was 87.92% Citronellal, 1% β- caryophyllene, 0.3% Citronellal acetate, 0.9% Citronellol, and 1.77% linalool, which comply to local industry standard.

Smart sensors, self-configuration, operational flexibility, and automatic learning, among others, are technological attributes from industry 4.0 appliable to the essential oil extraction by the steam distillation process. These operations are recognized by their simplicity. Nevertheless, lack of automatic controls, process monitoring, and self-adjustment lead to uncontrolled extraction, poor yields, low quality of products. It occurs because of overexposure to high temperatures and overspending resources like energy and water. As far as capacity utilization is concerned, the optimized process is key to planning and managing the production activities.
