Summary: Supercritical fluid extraction is a powerful tool for isolating components from different matrices. In this study, carbon dioxide in the supercritical state was used to extract oils from blackcurrant and black cumin seeds. The optimal conditions for the extraction process were determined using statistical experiment planning and the Box-Behnken design, taking into consideration the yield of the oils and the content of fatty acids. The results showed that increasing pressure led to an increase in extraction yield, while increasing temperature did not significantly affect the yield value.

Summary: Comparative study on the extraction of bioactive lipids from black cumin and basil seeds using conventional petroleum-based solvent and green solvent MeTHF showed that MeTHF extraction resulted in higher oil yield and more abundant nutrients. The oils extracted with MeTHF had higher tocopherols and phenolic compounds content, stronger antioxidant activities, and similar anti-inflammatory capacity compared to hexane-extracted oils.

Summary: An ultrasound-assisted method was used to extract phenolic compounds from defatted black cumin seeds, and the optimal extraction conditions were determined to be an ethanol concentration of 59.1%, extraction temperature of 44.6 degrees C, and extraction time of 32.5 min. Under these conditions, the total phenolic content and DPPH radical scavenging activity increased significantly compared to conventional extraction. The HPLC-UV analysis showed that the black cumin seed extracts contained high levels of epicatechin and rutin. Ultrasound-assisted extraction is a useful method for recovering polyphenols from defatted black cumin seeds.

Summary: In this study, the effects of different extraction methods on the quality attributes of black cumin seed oil were compared. Supercritical fluid extraction (SFE) was found to produce oil with higher amounts of unsaturated fatty acids, tocopherols, phytosterols, and polyphenols, as well as stronger antioxidants and antibacterial activity, making it a promising source for industrial applications.

Summary: Plant seeds, especially milk thistle seeds, contain valuable nonpolar and polar compounds with potential biological activity. This study developed an online method called supercritical fluid extraction (SFE)-supercritical fluid chromatography (SFC) to extract and analyze both types of compounds. Different transfer modes were compared, and the challenges of analyzing nonpolar and polar compounds were discussed. The versatility of online SFE-SFC and its potential in analyzing both types of compounds in a single sample were explored.

Summary: The study aimed to investigate the factors influencing oil extraction from milk thistle using supercritical CO2 as a green solvent. The effects of plant origin, cultivation year, seeds storage, high-pressure unit design, and initial plant material amount were examined. The results showed that adjusting the supercritical CO2 extraction parameters could improve the recovery of essential fatty acids and phenolic compounds, and the solid residues could be used for waste valorization.

Summary: The nutritional values of seeds from five cultivars of Elaeagnus mollis Diels were evaluated, and fatty acid profiles in samara oil extracted from these seeds were identified using GC-MS. Soxhlet extraction yielded a higher oil yield, while SF-CO2 extraction resulted in higher unsaturated fatty acid content. The ratio of unsaturated fatty acids to saturated fatty acids was 9:1, with linoleic acid, oleic acid, and palmitic acid being the most abundant fatty acids identified.

Summary: This study evaluated the feasibility of using supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE) to obtain a lipid-rich fraction and extracts rich in biocompounds from Pachira aquatica Aubl. (munguba) seeds. The results showed that the sequential process using non-toxic solvents is a high yield alternative to recover the rich oil and the phenolic fractions from munguba seeds.

Summary: A chemometric approach was used to compare the composition of vegetable oils extracted using supercritical CO2 extraction with conventional methods, showing that the CO2-SFE oils were similar to conventional oils with the added benefit of no solvent residues. The study confirmed the role of CO2-SFE as a suitable, environmentally safe, and efficient alternative method for extracting natural vegetable oils for food and pharmaceutical applications.

Summary: Appropriate soil conditions as a cultural practice are crucial for medicinal plant production. Adding vermicompost or inoculating with AMF can significantly improve the plant weight and antioxidant capacity of black cumin, while the main fatty acid components in the seed oil are linoleic acid, oleic acid, and palmitic acid. However, NPK application leads to higher saturated fatty acid content compared to other treatments.

Summary: This research focused on the sc-CO2 extraction of Elaeagnus angustifolia oil and its mathematical modeling. Experimental extraction was followed by modeling the process using mass transfer equations. The effects of main operational parameters were analyzed using Box-Behnken design, and the models were optimized using Genetic algorithm. The highest extraction yield of 84.9% was achieved under the optimum conditions determined by the models. The results from ANOVA indicated the high accuracy of the mathematical models for the supercritical extraction process.

Summary: This study evaluated the potential of supercritical fluid extraction (SFE) as a green alternative to Soxhlet extraction for obtaining oils from Opuntia ficus-indica (OFI) and Opuntia dillenii (OD) seeds. SFE with specific parameters produced oils rich in unsaturated fatty acids and tocopherols. The highest yield was achieved through Soxhlet extraction, and the most abundant fatty acid in all samples was linoleic acid. SFE of OFI seeds from Yemen resulted in the highest gamma-tocopherol content. Overall, SFE demonstrated its suitability for producing oils with potential applications in functional food and nutraceutical products.
