“…Owing to its high sensitivity, LC-HRMS is one of the most widely used chromatographic methods for the quantitative analysis of phenolic compounds in plant extracts [ 86 ]. Moreover, the optimization of various experimental parameters, such as the extraction solvent, column, mobile phase, and LC-HRMS conditions, is extremely important in the analysis of the phenolic content of oils obtained from plants [ 87 ]. The phenolic compounds are presumably responsible for the antioxidant ability of cinnamon leaf oil [ 88 , 89 ].…”

In this study, for the first time, the antioxidant and antidiabetic properties of the essential oil from cinnamon (Cinnamomum zeylanicum) leaves were evaluated and investigated using various bioanalytical methods. In addition, the inhibitory effects of cinnamon oil on carbonic anhydrase II (hCA II), acetylcholinesterase (AChE), and α-amylase, which are associated with various metabolic diseases, were determined. Further, the phenolic contents of the essential oil were determined using LC-HRMS chromatography. Twenty-seven phenolic molecules were detected in cinnamon oil. Moreover, the amount and chemical profile of the essential oils present in cinnamon oil was determined using GC/MS and GC-FID analyses. (E)-cinnamaldehyde (72.98%), benzyl benzoate (4.01%), and trans-Cinnamyl acetate (3.36%) were the most common essential oils in cinnamon leaf oil. The radical scavenging activities of cinnamon oil were investigated using 1,1-diphenyl-2-picryl-hydrazil (DPPH·), 2,2’-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid), and (ABTS•+) bioanalytical scavenging methods, which revealed its strong radical scavenging abilities (DPPH·, IC50: 4.78 μg/mL; and ABTS•+, IC50: 5.21 μg/mL). Similarly, the reducing capacities for iron (Fe3+), copper (Cu2+), and Fe3+-2,4,6-tri(2-pyridyl)-S-triazine (TPTZ) were investigated. Cinnamon oil also exhibited highly effective inhibition against hCA II (IC50: 243.24 μg/mL), AChE (IC50: 16.03 μg/mL), and α-amylase (IC50: 7.54μg/mL). This multidisciplinary study will be useful and pave the way for further studies for the determination of antioxidant properties and enzyme inhibition profiles of medically and industrially important plants and their oils.

“…Sesame oil is commonly employed in Chinese culinary practices due to its unique taste and health advantages [1][2][3]. Nevertheless, the presence of unethical practices within certain enterprises includes the production of sesame oil with inferior oils or the incorporation of avor-enhancing substances like vanillin, ethyl vanillin, and ethyl maltol into other edible oils [4]. This adulteration presents potential hazards to food safety, necessitating regulatory intervention.…”

“…This adulteration presents potential hazards to food safety, necessitating regulatory intervention. China's GB 2760 − 2014 "National Food Safety Standards for the Use of Food Additives" expressly prohibits the inclusion of such elements in edible vegetable oils [4,5]. In addition, comprehensive monitoring and detection technologies have been developed to detect and regulate these substances [4,6,7].…”

In addition, comprehensive monitoring and detection technologies have been developed to detect and regulate these substances [4,6,7]. Despite these measures, there remains a concern that alternative avourings could be used to mix with sesame oil in an attempt to evade detection and monitoring [8].…”

Gas chromatography-mass spectrometry (GC-MS) was utilized to identify the 5-(2-hydroxyethyl)-4-methylthiazole and γ-Nonanolactone in adulterated sesame oil. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was then employed for qualitative analysis of these flavors. A quantitative analysis method was successfully developed using methanol extraction and vanillin-D3 as an internal standard, with analyte recoveries ranging from 88.5–102.2% and relative standard deviations between 2.6% and 10.5% (n = 6). Subsequently, 31 batches of sesame oil from the market were tested, revealing that all samples contained the identified flavors within a relatively consistent range. However, some samples exhibited unusually high concentrations of these flavors, suggesting a potential risk of adulteration.
