“…[ 7 ] Compared to these traditional technologies, ultrasound assists in destructing some structures and cell degradation, while enzymatic treatment increases oil permeability through fruit tissues. [ 8 ] Thus, the ultrasound‐assisted aqueous enzymatic extraction (AEE) destroys the plant cell wall and accelerates oil release, leading to a high oil yield and short processing time.

For complete utilization of raw materials and edible oil production, the oil from golden melon seeds (GSs) is extracted via the cold‐pressing, hot‐pressing, and ultrasound‐assisted aqueous enzymatic extraction (AEE), and the fatty acid composition, and nutritional value of the extracted GS oils (GSOs) are analyzed. The volatile compounds present in the GSOs are determined using gas chromatography–mass spectrometry. The aroma profiles of different GSO samples are further distinguished by using an electronic nose. A total of 16 fatty acids are identified in the GSO samples, with atherogenic, thrombogenic, and nutritive value indices ranging from 0.142–0.151, 0.366–0.403, and 5.019–5.299, respectively. Moreover, 43 volatile compounds, including esters, hydrocarbons, alcohols, ketones, pyrazines, and aldehydes are identified. The cold‐pressed GSO presents fresh and fruity flavors, while the hot‐pressed GSO presents roasted, nutty, fatty, and fruity flavors, and the GSO obtained via AEE presents fatty and fruity flavors. The acid and peroxide contents of these oil samples are 0.69–079 mg g−1 and 5.17–5.79 mmol kg−1, respectively. The results indicate that the extraction method affects the fatty acid composition, flavor components, and physiochemical properties of the GSO. This study may help promote the development of edible GSO. Practical applications: With high demand for edible oils, it is of great significance to find natural edible oils from different sources. The oil in golden melon seeds is extracted by different methods. Their fatty acid composition and flavor components are analyzed. The GSO extracted via AEE method is rich in fatty acids composition. This work would guide the development of an edible GSO and increase the value of golden melon.

“…However, enzymes are expensive materials. Hence, the volume of enzymes might be a compromise between the extraction efficacy and the cost of enzymes [28] . While the volume gradually rose from 80 to 320 μL, the raise of the cordycepin content was recorded and the largest value of 0.41±0.03 mg/g was at 240 μL.…”

A continuing increase in total enzyme volume reaching over 240 μL would cause the depletion of the cordycepin content.…”

In this study, the employment of aqueous enzymolysis using alcalase with ethanolic ultrasonication extraction method was investigated. The cordycepin content was analyzed by using reversed‐phase high‐performance liquid chromatography with a diode array detector. The result showed that the highest cordycepin content of 0.4365±0.0309 mg/g could be obtained under extraction conditions including total enzyme volume of 240 μL, incubation time of 50 min, incubation temperature of 55 °C, and ultrasonic power of 840 W. The comparative studies of antioxidant activities of the extract were determined in terms of the DPPH free radical scavenging assay, ferric ion reducing power assay, and H2O2 scavenging assay. Additionally, the MTT assay was conducted to evaluate the anticancer activities of the extract, illustrating the cytotoxic property against Hep‐G2 cancer cells with the half‐maximal inhibitory concentration (IC50) value of 12.20±0.03 μg/mL compared to that of 0.36±0.03 μg/mL for ellipticine, MCF‐7 cancer cells with the IC50 value of 11.60±0.09 μg/mL compared to that of 0.51±0.04 μg/mL for ellipticine, and Lu cancer cells with the IC50 value of 34.50±0.25 μg/mL compared to that of 0.32±0.03 μg/mL for ellipticine.

“…As per a previously described method [ 26 ] with slight modifications, 0.1 mL of the 95% ethanol volume fraction from different concentrations of tree peony pod polysaccharides was added to 3.9 mL of 25 mg/L DPPH ethanol solution. After incubation for 30 min in the dark, the absorbance was measured at 517 nm and counted as the Asample.…”

We adopted and developed an ultrasonic-assisted extraction method to obtain polysaccharides from tree peony pods using polyethylene glycol (PEG) as the solvent. The technological parameters have been designed as a single factor to enhance the tree peony pod polysaccharide extraction yield. Specific conditions (ultrasound irradiation power, 250 W; ultrasound irradiation time, 30 min; reaction temperature 50°C; liquid-solid ratio, 25 mL/g; and concentration of PEG, 0.2 g/mL) generated an experimental yield of 14.14% ± 0.44%. Subsequently, the monosaccharide composition of the tree peony pod polysaccharides was determined by HPLC using a 1-phenyl-3-methyl-5-pyrazolone precolumn derivatization method. The results indicated that tree peony pod polysaccharides contained mannoses, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose, arabinose, and fucose with a molar ratio of 1.44 : 2.87 : 0.32 : 18.99 : 3.99 : 10.21 : 0.96 : 1.85 : 0.21. The tree peony pod polysaccharides obtained are mainly galacturonic acid and galactose, which are acidic polysaccharides. Finally, the antioxidant activities (DPPH and FRAP) of the tree peony pod polysaccharides were assessed, and the compounds exhibited moderate antioxidant activities.
