“…Due to this last difference, the relative amount of sesquiterpenes was higher in the SHSDACD VOs, Table 2 . The present results are in accordance with HD-obtained essential oils of rosemary from Morocco [ 34 , 35 ] while Chinese [ 19 , 36 ], and French rosemary essential oils presented additionally verbenone (2.0–6.6%, respectively) [ 37 ]. Conversely, a Turkish HD essential oil showed p -cymene (44.0%), linalool (20.5%), and γ-terpinene (16.6%) as the main components [ 38 ].…”

The demand for more suitable eco-friendly extraction processes has grown over the last few decades and driven research to develop efficient extraction processes with low energy consumption and low costs, but always assuring the quality of the volatile oils (VOs). The present study estimated the kinetic extraction and energy consumption of simultaneous hydro- and steam-distillation (SHSD), and SHSD assisted by carbon dioxide (SHSDACD), using an adopted modelling approach. The two isolation methods influenced the VOs yield, chemical composition and biological activities, namely, antioxidant, anti-glucosidase, anti-acetylcholinesterase and anti-inflammatory properties. SHSDACD provided higher VOs yields than the SHSD at a shorter extraction time: 2.8% at 30 min vs. 2.0% at 120 min, respectively, for Rosmarinus officinalis, 1.5% at 28 min vs. 1.2% at 100 min, respectively, for Lavandula angustifolia, and 1.7% at 20 min vs. 1.6% at 60 min, respectively, for Origanum compactum. The first order and sigmoid model fitted to SHSD and SHSDACD, respectively, with R2 value at 96% and with mean square error (MSE) < 5%, where the k distillation rate constant of SHSDACD was fivefold higher and the energy consumption 10 times lower than the SHSD. The rosemary SHSD and SHSDACD VOs chemical composition were similar and dominated by 1,8-cineole (50% and 48%, respectively), and camphor (15% and 12%, respectively). However, the lavender and oregano SHSDACD VOs were richer in linalyl acetate and carvacrol, respectively, than the SHSD VOs. The SHSDACD VOs generally showed better capacity for scavenging the nitric oxide and superoxide anions free radicals as well as for inhibiting α-glucosidase, acetylcholinesterase, and lipoxygenase.

“…Pre-flowering resulted in the highest essential oil content (1.68%) which was 16% and 20% higher than mid-flowering and post-flowering, respectively (Figure 2). When comparing these essential oil content findings with the earlier studies, diverse results were found, such as 2.73%-3.30% (Dzięcioł, 2021), 0.72%-1.73% (Afshar et al, 2021), 1.25%-1.38% (Oualdi et al, 2021), 1.5% (Aouadi et al, 2021), 2.8% (Ouknin et al, 2021), 0.5% (Karadağ et al, 2022), 1.35% (Elyemni et al, 2022), 1.35%-1.60% (Xylia et al, 2022). In Southern Iran, Afshar et al (2021) reported that rosemary essential oil content began to increase in August and peaked (1.73%) at the beginning of the cold season (November), and following that the accumulation of essential oil production gradually decreased, reaching its lowest point in February (0.72%).…”

Rosemary is an aromatic shrub native to the coasts of the Mediterranean region. Understanding the changes of chemical composition of essential oil is critical for more targeted rosemary harvesting, which can lead to higher-quality essential oils for agro-food, medicinal, and cosmetics uses. Therefore, rosemary plants were harvested at pre-flowering, full-flowering, and post-flowering stage grown in the experimental area of the Department of Field Crops at Çukurova University in order to determine the most suitable harvest time for the highest amount of essential oils and their important compounds. Essential oil content decreased slightly from the pre-flowering to post-flowering. The highest essential oil content (1.68%) was determined at the pre-flowering stage. Twenty-eight compounds were found representing 95.74%-96.74% of the total essential oil. The major compounds for rosemary were camphor (28.43%-32.74%), 1,8-cineol (20.80%-22.61%), isoborneol (6.05%-7.28%), verbenol (5.17%-6.98%), and limonene (5.71%-6.23%), respectively. Consequently, the optimal harvest time in terms of essential oil content, as well as camphor, 1,8-cineole and limonene content, may be considered as pre-flowering stage.

“…Tese were mainly under the dependency of extraction technique and the interaction of domestication with the extraction technique. [30,[32][33][34][35][36]. As discussed in the study by Bajalan et al [32], ROEOs from Italy, Morocco, Tunisia, and Turkey were reported to have 1,8cineole as the main component, accounting for over 40% [34].…”

We aimed at comparing the effects of domestication and extraction technique on the chemical profiling and antioxidant and antimicrobial activities of Rosmarinus officinalis essential oil (ROEO). This was isolated from wild (WR) and cultivated rosemary (CR) using microwave-assisted extraction (ME) and Clevenger hydrodistillation (CH). Domestication was the main variability source in ROEO constituents, while yield was equally determined by domestication and extraction techniques. Our results revealed important variations, owing to domestication and isolation technique, in terms of ROEO yield (1.10–2.85%), major compounds: α-pinene (14.07–42.03%), camphene (2.26–8.19%), β-pinene (0.35–3.76%), α-terpinene (0.55–2.92%), p-cymene (1.22–4.18%), limonene (0.64–2.79%), 1,8-cineole (31.73–40.72%), β-myrcene (2.09–3.2%), linalool (0.22–1.94%), camphor (12.12–19.66%), borneol (0.53–1.67%), and α-terpineol (1.46–7.45%) as well as minimal inhibitory concentration (MIC, 6.17–15.50 μg/mL), and antioxidant activity (IC50, 2.61–8.58 mg/mL). WR performed better in terms of yield, limonene, cineole, camphor, MIC, and IC50, while the remaining compounds were better expressed in CR. ME displayed high records of ROEO traits except for limonene, camphor, and verbenone (better expressed in CH). Principal component analysis confirmed the obtained findings via the separation of WR, CR, and techniques through the first two components (over 93% of data variability). In conclusion, R. officinalis domestication results in differentiated effects on ROEO traits, fostering a better accumulation of some compounds but reducing yield of other compounds and therefore antioxidant along with antimicrobial activity. ME could be recommended as a green method for ROEO isolation since it was more efficient in terms of the investigated ROEO traits.
