“…The highest quality oil can be extracted at low temperatures (Yousefi et al, 2019). Current findings regarding the yield and explanation of supercritical fluid extraction (SCFE) closely align with the outcomes reported by (Rajput et al, 2023) for the extraction of essential oil from clove buds. Values are presented as the mean ± standard deviation of three samples.…”

This study used the hydrodistillation method to extract essential oil from Cannabis sativa (C.sativa) leaves, while its chemical composition was examined through gas chromatography-mass spectrometry. Experiments were conducted on alloxan-induced hyperglycemic rabbits (albino), with metformin as the reference medication for comparative analysis to evaluate its potential in managing diabetes. Chemical analysis showed that the principal components of C.sativa essential oil were caryophyllene (46.63%), d-limonene (7.123%) and cis-β-farnescene (9.115%), humulene (13.153%) and trans-αbergamotene (6.592%). The minor components (˂5%) include α-pinene (3.720%), β-myrcene (1.910%), cineole (2.340%), valencene (1.614%), β-bisabolene (1.897%) and unidentified components (4.201-4.452%) were respectively. Intraperitoneal administration of C. sativa oil (0.7, 0.9 and 1.2µl/kg b.wt.) to hyperglycemia for 14 days resulted in a noteworthy decrease in both hepatic and fasting blood glucose levels. Meanwhile, there was a marked increase in the hepatic concentration of glycogen. The oil administration exhibited a reduced yet favourable anti-hyperglycemic potential compared to the reference antidiabetic drug. The study's findings indicate that the essential oil derived from C. sativa leaves cultivated in Pakistan is characterized as a Beta Caryophyllene chemotype. Remarkably, the oil demonstrated significant efficacy in lowering glucose levels and showed promise in mitigating hyperglycemia-induced dyslipidemic complications in rabbits induced with alloxan.

Citrus Essential Oils in Aromatherapy: Therapeutic Effects and Mechanisms

et al. 2022

Citrus is one of the main fruit crops cultivated in tropical and subtropical regions worldwide. Approximately half (40–47%) of the fruit mass is inedible and discarded as waste after processing, which causes pollution to the environment. Essential oils (EOs) are aromatic compounds found in significant quantities in oil sacs or oil glands present in the leaves, flowers, and fruit peels (mainly the flavedo part). Citrus EO is a complex mixture of ~400 compounds and has been found to be useful in aromatic infusions for personal health care, perfumes, pharmaceuticals, color enhancers in foods and beverages, and aromatherapy. The citrus EOs possess a pleasant scent, and impart relaxing, calming, mood-uplifting, and cheer-enhancing effects. In aromatherapy, it is applied either in message oils or in diffusion sprays for homes and vehicle sittings. The diffusion creates a fresh feeling and enhances relaxation from stress and anxiety and helps uplifting mood and boosting emotional and physical energy. This review presents a comprehensive outlook on the composition, properties, characterization, and mechanism of action of the citrus EOs in various health-related issues, with a focus on its antioxidant properties.

“…To further guarantee the effectiveness of scCO 2 extraction, suitable cosolvent and extraction conditions should be carefully established. Several studies have focused on the optimization of various extraction processes from different kinds of by-products from the food industry using surface response methodology (SRM) [ 21 , 22 , 23 , 24 ]. Furthermore, SRM allows us to analyze and process data from a response variable of interest that is influenced by different quantitative factors (independent variables) [ 25 ].…”

The leaves of Agave angustifolia Haw. are the main agro-waste generated by the mezcal industry and are becoming an important source of bioactive compounds, such as phenolic compounds, that could be used in the food and pharmaceutical industries. Therefore, the extraction and identification of these phytochemicals would revalorize these leaf by-products. Herein, maceration and supercritical carbon dioxide (scCO2) extractions were optimized to maximize the phenolic and flavonoid contents and the antioxidant capacity of vegetal extracts of A. angustifolia Haw. In the maceration process, the optimal extraction condition was a water–ethanol mixture (63:37% v/v), which yielded a total phenolic and flavonoid content of 27.92 ± 0.90 mg EAG/g DL and 12.85 ± 0.53 µg QE/g DL, respectively, and an antioxidant capacity of 32.67 ± 0.91 (ABTS assay), 17.30 ± 0.36 (DPPH assay), and 13.92 ± 0.78 (FRAP assay) µM TE/g DL. Using supercritical extraction, the optimal conditions for polyphenol recovery were 60 °C, 320 bar, and 10% v/v. It was also observed that lower proportions of cosolvent decreased the polyphenol extraction more than pressure and temperature. In both optimized extracts, a total of 29 glycosylated flavonoid derivatives were identified using LC-ESI-QTof/MS. In addition, another eight novel compounds were identified in the supercritical extracts, showing the efficiency of the cosolvent for recovering new flavonoid derivatives.
