“…Extraction efficiency could be enhanced by the moderate increase in temperature during ultrasonication. However, this increased temperature also has a negative effect on the bioactivity of the extract ( Rao et al, 2021 ; Rodsamran and Sothornvit, 2019 ; Saini et al, 2019 ; Vasantha Rupasinghe et al, 2011 ).…”

“…Cell wall fragmentation increases the solubility of bioactive compounds in the solvent. UAE is an economical, rapid, green, and developing technology appropriate for improving the efficiency of bioactive compound extraction ( Ranjha et al, 2021 ; Rao et al, 2021 ; Yu et al, 2019 ).…”

“…Solvent polarity is a crucial factor in ultrasonic-assisted extraction that primarily affects the solubility of targeted bioactive compounds. Moreover, changes in the solvents used during treatment will affect the ultrasonic efficiency and the stability of flavonoids ( Chaves et al, 2020 ; Rao et al, 2021 ; Sharma et al, 2019 ). Acidity, temperature, sample to solvent volume ratio, and the number and time intervals of individual extraction steps, also play a crucial role in the extraction procedure.…”

“…Furthermore, degradation of heat-sensitive substances that extracted earlier might occur due to prolonged cavitation and thermal effect of ultrasound. A more extended time may lead to an inefficient extraction ( Nishad et al, 2019 ; Ranjha et al, 2021 ; Rao et al, 2021 ; Yu et al, 2019 ).…”

As the highest yield crop worldwide, citrus peels that possess bioactive compounds were discarded as a futile by-product. Ultrasonication with environmentally friendly solvent (50% ethanol and ddH 2 O) were used in the present study to extract flavonoids from Citrus depressa Hayata peels with extraction period and fruit maturity as other variables. DPPH scavenging activity was investigated. Qualitative flavonoid content analysis was done by UV/Vis and FTIR-ATR spectra. Quantification of flavonoid using LC-MS/MS found that solvent type, fruit maturity, and ultrasonication period significantly affect the extracted flavonoid yield (p < 0.05). Extraction using 50% ethanol showed a higher yield than ddH 2 O. Flavonoid content was also higher in unripe than ripe samples. Nobiletin, tangeretin, and rutin were dominant among the identified compounds in all sample treatments. Flavonoid content in Citrus depressa Hayata extract was found to negatively correlate to DPPH scavenging activity, which needs further research to identify other bioactivities of these flavonoids.

Essential Oils - Advances in Extractions and Biological Applications

View full text Add to dashboard Cite

Essential oils are formed by a complex matrix of substances that are biosynthesized in the secondary metabolism of plants. Nowadays, different ecofriendly extraction techniques (e.g., ultrasound-, microwave-, enzyme-assisted extraction, and supercritical fluid by CO2, etc.) have been adopted to obtain essential oils. These techniques provide unique quality of essentials oils or extracts from aromatic plants in a short time with high energy savings. Essential oils not only impart aroma, but also possess antimicrobial and antioxidant activities. Health limitations in the use of synthetic additives have drawn researchers’ attention towards essential oils as safe natural preservatives. Therefore, this chapter summarizes novel technologies to recover essential oils or extracts. In addition, it focuses on application of essential oils and their constituents as green preservatives to retard microbial growth and oxidative spoilage.
