“…In the MAE method, the direct mutual influence of the microwave on the ethanol aqueous solution and the water inside the materials exist in the biomaterial cells to rupture the cells and effuse endocellular components into the solvent, quickly increasing the saponins extraction yield. A similar phenomenon was also observed in the literature [54,55]. Hence, MAE was more effective than the traditional techniques for saponins extraction.…”

A microwave-assisted extraction (MAE) method was applied to separate saponins from Sapindus mukorossi pericarps. The most important factors of the six extraction parameters were selected using Plackett–Burman designs; therefore, the further extraction procedure was optimized using the Box–Behnken designs; meanwhile, the optimum processing parameters and well-pleasing saponins extraction rate were inferred. The final operation conditions were the ethanol concentration of 40%, soaking time of 3 h, particle size of 80–100 meshes, extraction time of 13 min, solvent-solid ratio of 19 mL/g, and microwave power of 425 W. Based on the optimal extraction parameters, the extraction rate of the saponins by means of MAE technique reached 280.55 ± 6.81 mg/g, which exceeds yields acquired using conventional manners. Saponins from S. mukorossi have obvious xanthine oxidase inhibitory properties in vitro compared with allopurinol. The saponins displayed a type of competitive inhibition of xanthine oxidase. In conclusion, a MAE technique in association with a response surface design provides an efficient extraction tactics, which could sufficiently isolate saponins from S. mukorossi pericarps; further, this technique could be applied to the dissociation of other bioactive substances from plant sources. In addition, the saponins may be a promising alternative to conventional medicine to treat gout and other inflammation-associated disorders to mitigate the side effects of traditional drugs.

“…The results indicated that higher microwave irradiation power would lead to the degradation, condensation, or isomerization of essential oil components (Chen et al, ). A similar phenomenon was observed by Castejón et al (), Li et al (), and Hu et al (). Hence, the optimal microwave power should be dependent on the balance between the dual influences.…”

“…The F ‐value and the P ‐value of the lack of fit were 6.79 and 0.135, respectively, which suggested that they were not significantly relative to the pure error and the model equation was suitable for predicting the extraction of SCO. Besides, the determination coefficient in the experimental model also implied a good correlation ( R 2 = 91.11%) between the experimental results and their predictions (Chanioti and Constantina, ; Chen et al, 2017; Hu et al, ). The relatively low value of the coefficient of variation in Table showed a good precision (CV = 5.13) and reliability of the experiments (Sodeifian et al, ; Zhang et al, ).…”

In this article, to increase the extraction efficiency and quality of single-cell oil (SCO) from Mortierella isabellina NTG 1-121 (MIN) in the SCO extraction, ultrasound in combination with microwave was applied. The best extraction conditions (microwave power 400 W; microwave time 3.7 min; ultrasonic time 40.5 min; ultrasonic power 500 W; and the material to solvent ratio 1:12.3 [w/v]) were achieved at room temperature of 25 AE5 C, using response surface methodology (RSM). Under these conditions, the extraction yield of SCO was up to 92.24% and the SCO yield was 178.13 AE0.17 mg g −1 (wet cell). Compared with ultrasound-assisted extraction (UAE) and acid-heating extraction (AHE), the quality and yield of SCO obtained using the ultrasonic-assisted/microwaveassisted extraction (UMAE) were improved. The present study suggests that UMAE can be an alternative for the extraction of SCO from MIN. The oil is rich in oleic acid (ca. 43.98%), linoleic acid (ca. 11.56%), and gamma linolenic acid (ca. 11.38%), which is comparable to the fatty-acid composition of several edible oils.

“…The potential functions and nutritive value of silkworm pupae have not been fully recognized . Recent publications demonstrate that silkworm pupae are characterized by high levels of protein, lipids, and biologically active substances such as vitamin . It is documented that the A. pernyi pupae powders contain 71.9% of crude protein, compared with 48–60% in B. mori pupae, with all essential amino acids included .…”

A comprehensive identification of lipid compositions and tocochromanols inAntheraea pernyi (A. pernyi) and Bombyx mori (B. mori) pupae oil is reported in the present study. Fatty acid profiling shows that both oils contain high levels (79.67% vs 71.11%) of unsaturated fatty acids, especially linoleic acid and linolenic acid. Moreover, linolenic acid is preferentially enriched at the sn-2 positions of triacylglycerols (TAGs). Liquid chromatograph-mass spectrometry (LC-MS) analysis demonstrates that POO (TAG with one palmitoyl and two oleoyls) is the primary TAG form with percentages of 20.18% in A. pernyi and 15.00% in B. mori. The dominating phospholipid species are phosphatidylcholine (PC, 30.40% vs 54.61%) and phosphatidylethanolamine (PE, 34.82% vs 20.39%). Four sterol constituents with total contents of 382.56 ± 3.12 and 371.65 ± 2.98 µg g −1 are identified and analyzed quantitatively. Additionally, the levels of tocochromanols (20.15 ± 0.89 vs 17.15 ± 0.71 mg g −1 ) are quantified in both silkworm pupae oils. Overall, silkworm oil acts as an enriched source of functional lipids and tocochromanols. Practical Applications: A systematic investigation on the principal lipid classes and tocochromanols of Antheraea pernyi pupae and Bombyx mori pupae oil is reported in this study.
