“…When compared the oil yield without ultrasound treatment for extraction at the same condition, the maximum oil yield with ultrasound treatment was eventually 2 times more than the extraction without ultrasound treatment, which were 79.88% and 38.93%, respectively. This result was agreed with the finding from other researcher who stated that ultrasound could increase the oil yield and quality with faster rate of extraction (Bagher Hashemi, Khaneghah, & Akbarirad, ).…”

In this study, ethanol was used as a polar solvent to extract hazelnut oil, with ultrasound aid in the first 15 min of extraction. A Box–Behnken design was used for optimization in term of ultrasound amplitude (30%, 60%, and 90%), extraction temperature (28, 38, and 48°C), and extraction time (30, 60, and 90 min). All three factors showed positive effects on the oil extraction. The results showed that the oil yield and quality of extracted oil were significantly affected by the application of ultrasound. Ultrasound treatment had increased the oil yield from 38.93% up to 79.88%. The optimum conditions were identified at 90% of ultrasound amplitude, 29°C of extraction temperature, and 51 min of extraction time. Under these conditions, the predicted maximum oil yield was 55.39% with the minimum FFA value, iodine value and peroxide value of 1.75%, 14.52 g/100 g, and 10.50 meq g O2/kg, respectively. Practical applications Plant oil has become the first choice for edible oil due to large percentage of unsaturated fatty acid, which has been reported that it could help to reduce the bad cholesterol in human body. Hexane is the solvent that commonly used in solvent extraction stage but it is highly volatile and might cause safety issue for extraction plant. Therefore, this study aims to use ethanol to replace hexane. This research introduces the optimized ultrasound‐assisted ethanol solvent extraction process to the manufacturer. Ultrasound could enhance the oil yield which can produce low‐cost hazelnut oil to the consumer.

“…This phenomenon can be attributed to the absence of more essential oil within the plant to extract, or to equilibrium of the whole system, which marks the end of the extraction process . In addition, at long extraction time, the oil concentration increases in the solvent resulting in a reduction in the diffusion rate of oil from the meal to the solvent . While the ultrasonic time was too long, the reaction system states to emulsify and the rate of oil would even reverse and the cavitation effect would lessen or even diminish at this time .…”

The present study evaluates the suitability of ultrasound pretreatment in n‐hexane solvent as well as enzymatic treatment with cellulase enzyme to extract oil from peanut seed powders. To optimize this process, the effects of ultrasonic time (0–70 min), cellulase enzyme concentration (0–2%) and pH (4–5.5) are investigated on peanut oil extraction yield (EY) as well as the quality attributes of the extracted oil containing total phenolic content (TPC), peroxide value (PV), and color parameters of L, a, and b using response surface methodology (RSM). The optimum condition of ultrasound‐assisted enzymatic extraction using n‐hexane solvent (UAEE) is found as ultrasonic pretreatment time of 33.23 min, cellulase concentration of 1.47%, and pH of 4.61 before incubation process at temperature of 56 °C for 120 min. Scanning electronic microscopy (SEM) represented considerable interspaces, holes, and porous structure of peanut meal after optimal UAEE treatment compared to that after shaking incubation extraction using n‐hexane solvent (SIE). It is found that the peanut oil extracted by optimal UAEE treatment had considerable high levels of L color parameter and TPC and significantly more EY and b color parameters than those extracted by SIE, ultrasound‐assisted aqueous enzymatic extraction (UAAEE), and aqueous shaking incubation extraction (ASIE) treatments. Practical Applications: This paper describes an innovative oil extraction method of ultrasound‐assisted enzymatic process using n‐hexane solvent. This new extraction technique makes it possible to increase the extraction yield, total phenolic content, and yellowness of extracted peanut oil. The results illustrated that ultrasound‐assisted enzymatic extraction using n‐hexane solvent method was a far more efficient extracting technique than the individual shaking incubation extraction using n‐hexane solvent, ultrasound‐ assisted aqueous enzymatic extraction and aqueous shaking incubation extraction treatments and would be a promising alternative for conventional oil extraction techniques. Comparison of two treatments of optimal ultrasound‐enzymatic extraction and individual shaking incubation extraction of oil from peanut seed powders.

“…Power ultrasound induces phenomena in the medium, such as acoustic streaming and cavitation, which leads to intense agitation and mass transfer enhancement. Ultrasound-assisted extraction techniques therefore accelerate the release of the essential oils from aromatic plants as they facilitate the penetration of the solvents in the plant material [ 39 ]. Cavitation involves the formation, expansion and growth of small liquid-free zones or bubbles.…”

Phytochemical research based on ethnopharmacology is gaining interest in industries such as functional food, nutraceuticals, cosmetics and pharmaceutical industries. Plants and plant extracts are a rich source of bioactive secondary metabolites. These compounds are often involved in plant protection against biotic or abiotic stresses. The exploitation of available technologies should be oriented and intensified to extend and enhance the continued usefulness of the plants as renewable sources of chemicals, especially medicinal compounds. This current contribution is focused on extraction and analytical techniques for their isolation from the oregano species, their characterization and their potential antioxidative, as well as their antimicrobial, antifungal and anticarcinogenic properties. The work is structured rendering to the different steps involved in the research; starting with extraction and sample preparation, followed by discussing the analytical techniques employed for the isolation and identification of compound/s responsible for the biological activity and methods and techniques for biological activity assessment.
