This study investigates an aqueous salt process (ASP) combined with microwave-assisted extraction (MAE) for the seed oil extraction from yellow horn (Xanthoceras sorbifolium Bunge). The NaCl concentration in the oil extraction process affected the oil extraction yield. Box–Behnken design (BBD) and response surface methodology (RSM) were used to optimize the extraction process. The optimal operating parameters were: 24 g/L NaCl, 300 W microwave power, 4:1 water to material ratio, an 80 min extraction time, and 45 °C extraction temperature. The chemical composition of the extracted seed oil was analyzed using gas chromatography–mass spectrometry (GC-MS). This extraction technique for yellow horn seed oil provided high throughput and high-quality oil. The present research offers a kind of green extraction method for edible oil in the food industry.

Deep eutectic solvents (DESs) have attracted significant attention as green media for the extraction and separation of natural compounds from Chinese medicine. In this study, a hydrophobic DESs-based microwave-assisted extraction (MAE) was successfully used to efficiently extract baicalin from Scutellaria baicalensis Georgi. Firstly, DecA: N4444-Cl (DES-1 , molar ratio 1 : 2) was screened and selected as the most appropriate DES by comparing the extraction yield in different hydrophobic DESs. Based on the extraction yield of baicalin, response surface methodology (RSM) was employed to model and optimize the parameters (extraction temperature, liquid-solid ratio, and extraction time). Furthermore, the maximum yield of 106.96 mg·g−1 was achieved under optimum conditions in DES-containing aqueous solutions (33 vol% water content), which reached a similar level that was conducted using the pharmacopoeia procedure (104.94 mg·g−1). These results indicated that the proposed method is an excellent alternative for the extraction of baicalin.

Abstract A potential method called microwave-assisted aqueous two-phase extraction (MA-ATPE) was developed for concurrent extraction and purification of gentiopicroside from Gentiana scabra Bunge. Formation characteristics of aqueous two-phase system (ATPS) composed of ethanol and 25 kinds of salts were investigated; K2HPO4 (w/w, 21.71%) and ethanol (w/w, 40.72%) were determined to be the optimal compositions of ATPS. Response surface methodology based on Box–Behnken design was used to investigate the extraction conditions, the optimal parameters were summarized as follows: 80°C of extraction temperature, 31 s of extraction time, 11:1 (mL/g) of liquid-to-solid ratio, 100 meshes of particle size and 806 W of microwave power. Under these conditions, the extraction yield of gentiopicroside was 65.32 ± 0.24 mg/g with a recovery of 96.51%. Compared with other four methods, the purity of gentiopicroside in the crude extracts reached 17.16 ± 0.25%, which was significantly higher than that of smashing tissue extraction, microwave assisted-extraction, ultrasonic-assisted extraction and heat reflux extraction, respectively. In addition, the phase-forming salt can be recyclable. Therefore, MA-ATPE was an excellent and alternative technique to the conventional extraction approaches of gentiopicroside.

Objective: In this study, the extraction of oil from Pistacia terebinthus L’s seeds grown in Elazig-TURKEY and called menengic in domestic region was investigated. Crude oil content of the seeds obtained from this region was determined as approximately 47% (w/w). Methods: Effects of the parameters such as extraction time, temperature, seeds/solvent ratio (dosage), the particle size of seeds and type of solvent were examined on the oil extraction yield. In this context, it has concluded that up to a certain point, the extraction time has increased the yield of oil extracted. But the extraction temperature showed activity as depending on the solvent type. Results: As expected, it has been observed that the yield of oil has decreased depending on the increase in particle size and dosage as well. The mathematical model obtained by solving Fick's second law under the appropriate boundary and initial conditions were used to calculate diffusion coefficients for the extraction process. Diffusion coefficients for the seeds with a particle size of 0.55 mm were found to be between 1.15x10-11 and 1.86x10-11 m2s-1. To compare the extraction yield of Pistacia terebinthus L’s seeds with that of sunflower at the same conditions, the diffusion coefficients of sunflower seeds were calculated in the range of 9.11x10-12 and 1.13x10-11 m2s-1. Conclusion: These figures show that the diffusion coefficients calculated for both oily seeds are nearly equivalent to each other. The fatty acid composition of extracted oil from Pistacia terebinthus L’s seeds was determined by GC-FID. The GC-FID results showed that oleic, linoleic (ω-6) and palmitic acid were main fatty acids in the oil obtained from menengic seeds.

Vietnam is a leading producer and exporter of products harvested from plants of the family Piperaceae such as green pepper, black pepper, red pepper and white pepper. In this study, an attempt is made to examine the essential oil extraction process with the material of white pepper grown and harvested in Phu Quoc island, Vietnam. To maximize essential oil production, three factors consisting the ratio of materials and solvents, extraction time and extraction temperature were selected and optimized. The surface response methodology optimization resulted the highest yield of 3.6%, achieved at the ratio of material and water ratio of 1:20 g/g, extraction time of 96 min and at 130 ºC. A high F values, low P values (< 0.0001), the determination coefficient (R2 = 0.9993) and a non-significant lack of fit suggested a strong correlation between actual and predicted values of the responses. The essential oil obtained was determined for chemical composition by gas chromatography-mass spectrometry (GC-MS) method. The GC-MS results showed that major constituents existing in the oil sample were limonene, 3-carene, sabinene, β-pinene, α-pinene and α-phellandrene, accounting for 27.059, 23.345, 17.903, 9.996, 5.167 and 4.588%, respectively.

The extraction of phenolic compounds from olive leaves was optimized using three glycerol-based deep eutectic solvents (DESs) with lysine, proline, and arginine. A three-level Box–Behnken design was used to examine the influence of the liquid/solid ratio, concentration of DESs, and extraction temperature on the yield of the extraction process. A second-order polynomial model was used for predicting the polyphenol extraction yield. The optimal predicted conditions were used for extractions and they provided the highest total phenol yields with the glycerol–lysine exhibiting the best performance. Quantification of tyrosol, hydroxytyrosol, oleuropein, luteolin-7-O-glucoside, and rutin in the extracts showed high content in tyrosol in all DESs, particularly with glycerol–lysine and relatively similar contents with other studies for the other phenolic compounds. Finally, a linear relationship between tyrosol content and the total phenolic content of the extracts was observed.

Microwave has been widely used in the extraction of many samples for its unique heating mechanism, short extraction time and high yield of extract. The microstructure characteristics of plant materials are closely related with macro-property and mechanism on mass transfer within matrix. Fractal geometry, with the ability to describe irregular objects provides a new language. Astragalus slice is a special and typical plant porous media. We characterize the microstructure of Astragalus slices irradiated by microwave at 600 and 900 W by using fractal dimension, with the aim to analyze the effect of the microwave power on the extraction yield and discuss further the relationship between the fractal dimensions and microstructure changes of sample during microwave assisted extraction process. It is found that the fractal scaling law of box counting method is not suitable for the apertures on the wall of trachea inside matrix, and Slit Island and mercury injection method may be used. Fractal dimensions of samples at microwave 600 W are smaller than that at 900 W. The smaller fractal dimension is in favor of effective components dissolution inside the slices, which led to extract with the 20 min irradiation of microwave at 600 W is higher than that at 900 W.
