“…The ensuing impacts can include the loss of pharmacological components, staining, off‐flavor/odor, and physical changes to EOs. There are common methods for extracting EOs, including hydrodistillation (Katekar et al., 2022; Taraj et al., 2019), solvent extraction (Park et al., 2022), steam distillation (S. Kumar et al., 2022), and modern techniques such as supercritical fluid extraction (Yousefi et al., 2019), microwave‐assisted hydrodistillation (Drinić et al., 2020), solvent‐free microwave extraction (Yingngam et al., 2022), and subcritical water extraction (Cheng et al., 2021).…”

For centuries, essential oils (EOs) have held a significant place in traditional medicinal practices worldwide and are commonly known for their aroma and taste. Among the 3000 recognized types, only 300 have commercial use in the food and pharmaceutical sectors. These potent natural extracts, derived from aromatic plants and herbs, have garnered attention not only in ancient healing traditions but also within modern health‐care systems. Their rich history is marked by a diverse array of therapeutic properties that have made them indispensable tools for promoting health and well‐being. Additionally, the utilization of EOs as food preservatives is an innovative and natural approach in extending the shelf life of various food products. In addition, EOs are beneficial in the treatment of cancer and other diseases. Because of their outstanding biological activities and health benefits, research on EOs has exploded in recent years. In present work, an intensive review was done on published data on therapeutic potential of some major EOs and their utilization as a preservative in food industries. Meanwhile, an investigation of the methods specifically used for the separation of EOs and regulatory considerations are also reported. The article concludes with comments on future trends.

“…1 Belonging to the Myrtaceae family, this woodland shrub is indigenous to Australia and New Zealand. Research into the chemistry of Kunzea species is limited to a few studies [2][3][4][5] with recent evidence indicating that the quality of wild harvested K. ambigua essential oil can be highly variable in both oil yield and profile. Oil yield can range from 0.2 to 2 % dry weight and major monoterpene components include α-pinene (0.6-62.5 %) and 1,8-cineole (3.6-14.5 %) while the major sesquiterpenes include globulol (0.5-22.6 %), viridiflorol (0.3-38.0 %) and ledol (1.3-4.8 %).…”

The therapeutic potential of Kunzea ambigua essential oil is experiencing increased market demand. However, commercial production is currently limited by variability of wild-harvested feedstock so that managed production from high yielding clones is desired. This study explored the utility of near infrared (NIR) reflectance spectroscopy to predict total extracted oil and the major terpenes from intact and ground K. ambigua leaves. Partial least squares regression enabled accurate prediction of total extracted oil and the concentration of α-pinene, globulol and viridiflorol but not α-terpineol (the major components). This was the case for both ground and intact leaf samples, though the coefficients of determination (r2) values were lower for the intact leaf samples (r2: 0.59 to 0.71, ratio of residual prediction to the deviation, RPD: 1.4-5.0, RMSEP: 0.53-2.27 mg/g) as compared to the ground samples (r2: 0.72-0.88; RPD: 1.9-8; RMSEP: 0.32-1.40 mg/g). In contrast, a NIR predictive model was produced for ground but not intact samples for 1,8-cineole (r2: 0.72; RPD: 1.9; RMSEP: 0.42 mg/g). Though the predictive models developed in this study were less accurate and less precise than for the intact samples, this technology could still be immediately useful and allow for rapid identification and screening for superior K. ambigua genotypes from native vegetation for both total extracted oil and preferred chemical profiles.

Numerous attempts have been made in recent years to assess the effects of various EO extraction techniques, and it has been discovered that some extraction methods can also result in the loss of specific chemical compounds (Bendahou et al, 2008).…”

IntroductionSpearmint essential oil is a valuable medical and food product. Spearmint essential oil is effective for the treatment of flatulence, indigestion, nausea, and colic along with Alzheimer, obesity, and fungal infections.MethodsThis study evaluated the quality and quantity of spearmint essential oil by examining some extraction strategies. The procedures were hydro-distillation, hydro-steam distillation, microwave-assisted hydro-distillation, and open hydro-distillation. The hydro-distillation had five pH levels (2, 4, 6, 8, and 10) and four NaCl concentrations (0.5, 1, 1.5, and 2%). microwave-assisted hydro-distillation at a power of 225 W was applied for 60, 90, and 120 minutes for process durations. The solvent extraction of herbal distillate obtained by an open hydro-distillation system was done using n-pentane and n-hexane to achieve a recovered essential oil by a rotary evaporator.Results and discussionThe results showed that the lowest pH in the hydro-distillation process led to obtaining double yield compared to the control. Additionally, at 1 and 1.5% NaCl concentrations, the oil yield increased by 12.86 and 20.87%, respectively. Although the yield was reduced by microwave-assisted hydro-distillation, however within 120 minutes, carvone increased by 12.7% and limonene decreased by 42.3%. The best quality of spearmint oil belonged to solvent extraction followed by rotary evaporator.
