“…A laboratory scale supercritical fluid extraction system (Aerospace Wujiang Electromechanical Equipment Co., Ltd., Guizhou, China) was used in the experiments for extraction of DSEO. The effects on the extraction yield of DSEO under various extraction situations, such as the particle size of raw materials, the extraction pressure, temperature, CO 2 flux, and the extraction time, were discussed to find the optimum parameters [6,10]. The single factor test was used in a series of experiments by keeping other factors constant in the optimization experiments.…”

“…Essential oils have been conventionally extracted using techniques for instance hydrodistillation, steam distillation, solvent extraction, cold pressing, as well as simultaneous distillationextraction methods, among others [4]. The disadvantages of these common methods are low efficiency, longer time duration, thermal degradation, loss of volatiles, and solvent residue [5,6]. The supercritical fluid extraction technique has been studied extensively as a promising alternative to conventional methods of extraction as it offers many advantages [7].…”

Purpose: To conduct gas chromatography-mass spectrometric (GC-MS) analysis of the chemical compositions of dill seed essential oil (DSEO) obtained by supercritical CO2. Methods: The impact on extraction yield were examined by single factor test, the particle size of dill seed, extraction temperature, time, pressure, as well as CO2 flux. The best extraction conditions were obtained by an orthogonal test. The chemical configurations of essential oil were examined by GC-MS analysis. Results: The optimal extraction conditions included an extraction time of 120 min, particle size of 60 mesh, CO2 flow of 25 L/h, temperature of 40oC, and pressure of 20 MPa. Under these conditions, the yield of essential oil was 6.7 %. Out of 38 recognized compounds, the main ones were D-carvone (40.36 %), D-limonene (19.31 %), apiol (17.50 %), α-pinene (6.43 %), 9-octadecenoic acid (9.00 %) as well as 9,12-octadecadienoic acid (2.44 %). Conclusion: A total of 38 constituents of the essential oil obtained by supercritical CO2 were identified. The findings may provide a theoretical basis for comprehensive utilization of dill seed essential oil (DSEO) from China.

“…It is also shown in Table 3 that the significant terms are different for five compounds. The adjusted coefficients of determination (R 2 adj ) in Table 3 are all greater than 0.82, which shows an adequate fit of the experimental data, compared to the R 2 adj reported in the literature (Cai et al, 2015;Xu et al, 2016;Shrigod et al, 2017).…”

Summary Varying material particle sizes represent a common contributing factor to the batch‐to‐batch variation of extraction yields. To increase the batch‐to‐batch quality consistency of extracts, a method was proposed to adjust the extraction conditions for different material particle sizes, taking the hydrodistillation extraction process of Radix Curcumae and Fructus Gardeniae as a case study. Statistical models were built for five sesquiterpenes including curcumenone, curcumenol, curdione, curzerenone and furanodienone, to quantitatively describe the effects of particle size and process parameters on their extraction yields. An increase in sodium chloride concentration remarkably increased the yields of curcumenone and curcumenol, and a larger solvent‐to‐solid ratio increased the yields of five sesquiterpenes. Under the adjusted process parameters for two different particle sizes, the yield for each compound was controlled to fall in the 90–110% target range. The proposed method can be applied to various extraction processes of foods and herbal medicines.

“…EOs can be obtained from different plants by many methods including hydro-distillation (HD), steam-distillation SD, solvent-free microwave extraction SFME, and supercritical fluid extraction SFE [4,5,6]. Previous studies showed that extraction methods could affect the composition of EOs and further result in different bioactivities [7].…”

Flos Chrysanthemi indici, an important medicinal and aromatic plant in China, is considered to have many different preservative and pharmacological properties. Considering the capability of essential oils (EOs), the present study is conducted to compare different extraction methods in order to improve yield and biological activities. Hydro-distillation (HD), steam-distillation (SD), solvent-free microwave extraction (SFME), and supercritical fluid extraction (SFE) are employed to prepare EOs from Flos Chrysanthemi indici. A total of 71 compounds are assigned by gas chromatography/mass spectrometry (GC–MS) in comparison with retention indices. These include 32 (HD), 16 (SD), 31 (SFME) and 38 (SFE) compounds. Major constituents of EOs differ according to the extraction methods were heptenol, tricosane, camphor, borneol, and eucalyptol. EOs extracted by SFME exhibit higher antioxidant activity. All EOs show varying degrees of antimicrobial activity, with minimum inhibitory concentration (MIC) ranging from 0.0625 to 0.125 mg/mL and SFME and SFE prove to be efficient extraction methods. EOs alter the hyphal morphology of Alternaria alternata, with visible bumps forming on the mycelium. Overall, these results indicate that the extraction method can significantly influence the composition and biological activity of EOs and SFME and SFE are outstanding methods to extract EOs with high yield and antimicrobial activity.
