“…The following conditions were applied: helium as carrier gas with 36.5 cm/s of linear velocity, injector temperature of 250 °C, oven temperature program of 60-240 °C at 3 °C/min, electron energy of 70 eV, interface temperature of 250 °C. Results were compared with MS library system NIST-98 and literature data [20].…”

“…As a consequence, the obtained EO is negligible. As oil bath temperature increases, the effect of cavitation increases, together with the increased solubility of solutes in the solvent, leading to the rise in the amount of EO yield [20][21]. However, the excessive increase in oil bath temperature might enhance EO thermal degradation, which decreases the amount of obtained EO Besides, the short amount of extraction time can ensure the cost of the process and limit the oxidation of essential oils.…”

The present study attempted to evaluate the suitable conditions for essential oil extraction from the fruit of Triphasia trifolia using hydrodistillation technique. The effect of various factors such as material size, solvent to solid ratio, heating temperature and distillation time, state of maturation, and fruit preservation on the oil yield was investigated. The physicochemical property, chemical composition, and biological properties were accessed. The highest yield of essential oil (7.9 mL/kg dry matter) from T. trifolia was obtained at optimal conditions such as fine particle size, solid to solvent ratio of 1:5, temperature oil bath of 140 °C, and distillation time of 3 h. The state of maturation of the fruits significantly affects the essential oil yield and insignificantly influences chemical composition based on the gas chromatography-mass spectrometry (GC-MS) analysis. It was found that the essential oil yield decreases significantly when ripened fruits are not kept in cool conditions before distillation. It implied that ripened fruits should be immediately processed or kept in cool storage to maintain the essential oil yield. Our findings will help produce high-quality essential oil from T. trifolia at a pilot or industrial scale.

Pomelo peel-derived essential oils have been gaining popularity due to greater demand for stress relief therapy or hair care therapy. In this study, we first performed optimization of parameters in the pomelo essential oil extraction process on a pilot scale to gain better insights for application in larger scale production. Then extraction kinetics, activation energy, thermodynamics, and essential oil quality during the extraction process were investigated during the steam distillation process. Three experimental conditions including material mass, steam flow rate, and extraction time were taken into consideration in response surface methodology (RSM) optimization. The optimal conditions were found as follows: sample weight of 422 g for one distillation batch, steam flow rate of 2.16 mL/min and extraction time of 106 min with the coefficient of determination R2 of 0.9812. The nonlinear kinetics demonstrated the compatibility of the kinetic model with simultaneous washing and unhindered diffusion with a washing rate constant of 0.1515 min−1 and a diffusion rate constant of 0.0236 min−1. The activation energy of the washing and diffusion process was 167.43 kJ.mol−1 and 96.25 kJ.mol−1, respectively. The thermodynamic value obtained at the ΔG° value was −35.02 kJ.mol−1. The quality of pomelo peel essential oil obtained by steam distillation was characterized by its high limonene content (96.996%), determined by GC-MS.

“…Most of the research objects were plants with natural flavors, such as Rutaceae plants. Some achievements have been accomplished in the extraction method and technology of plant essential oils (Dao et al., 2019; Dao, Do, et al., 2020; Dao, Ngo, et al., 2020; Dao et al., 2021). Only a few studies reported on the essential oil extraction technology and chemical substances of thuja because of the scarcity of its resources.…”

Study on SFE‐CO₂ and chemical composition of thuja essential oil

Thuja (Thuja sutchuenensis Franch.) (family Cupressaceae) is a Chinese endemic plant once declared extinct in China. After being rediscovered in 1999, it attracted the attention of domestic scholars. This study aimed to investigate the extraction process and composition of the essential oil from thuja to provide a reference for further research. The main xylem of thuja collected from the Qinling‐Bashan mountains was used as the experimental material. The essential oil of thuja was extracted by the supercritical carbon dioxide fluid extraction (SFE‐CO2) process, and the composition of the essential oil was detected by gas chromatography‐mass spectrometry (GC‐MS). Extraction pressure, extraction temperature, and extraction dynamic time were the main factors influencing the extraction rate. The optimal conditions for the extraction include the following: maintaining the extraction pressure at 20 MPa, extracting for 60 min at 45 °C, and maintaining the CO2 flow rate at 1.5 L min–1 at 120 °C. Under the optimal extraction conditions, the oil extraction rates of three verification experiments were 18.87, 18.63, and 19.07%. The GC‐MS detected 136 components from the extracted thuja essential oil, and 75 components were identified. The main components of the essential oil were cis‐thujopsene (23.54%) and cedrol (13.08%). In this study, the optimal process for SFE‐CO2 of essential oil from the xylem of thuja was obtained. Under this optimized process, the average oil content was 18.86%.
