“…Currently, REOs are mainly extracted by water distillation and detected by GC/MS (Kallimanis et al, 2022;Mwithiga et al, 2022;Quintana et al, 2021). Elyemni et al (2019) and Akhbari et al (2018) developed a modern microwave-assisted hydrodistillation in their studies, which can significantly improve the extraction efficiency and provide the desired REO with much more oxygenated compounds than those of traditional methods while ensuring the same REO yield.…”

“…It is a commercially important aromatic evergreen shrub with dark green leaves, pale blue flowers, and upright stems (Figure 1) (Farkhondeh et al., 2019), and it is regionally native to the European countries and the Mediterranean region. Nowadays, it is widely cultivated all over the world as a popular decorative plant (EFSA Panel on Additives et al., 2022) and an economically promising crop (Bourhia et al., 2019), and its main producing countries are Spain, Morocco, and Tunisia (Mwithiga et al., 2022). In particular, rosemary is cultivated in significant amounts in China, India, Algerian, Northern Europe, England, and North America.…”

Rosemary (Rosmarinus officinalis L.) is one of the most famous spice plants belonging to the Lamiaceae family as a remarkably beautiful horticultural plant and economically agricultural crop. The essential oil of rosemary has been enthusiastically welcome in the whole world for hundreds of years. Now, it is wildly prevailing as a promising functional food additive for human health. More importantly, due to its significant aroma, food, and nutritional value, rosemary also plays an essential role in the food/feed additive and food packaging industries. Modern industrial development and fundamental scientific research have extensively revealed its unique phytochemical constituents with biologically meaningful activities, which closely related to diverse human health functions. In this review, we provide a comprehensively systematic perspective on rosemary by summarizing the structures of various pharmacological and nutritional components, biologically functional activities and their molecular regulatory networks required in food developments, and the recent advances in their applications in the food industry. Finally, the temporary limitations and future research trends regarding the development of rosemary components are also discussed and prospected. Hence, the review covering the fundamental research advances and developing prospects of rosemary is a desirable demand to facilitate their better understanding, and it will also serve as a reference to provide many insights for the future promotion of the research and development of functional foods related to rosemary.

“…Similar to the camphor content, the highest values for the 1.8-cineole content were obtained in the pre-flowering stage (22.61%). When compared the 1.8-cineole content with the earlier studies, diverse results were found, such as 6.19%-10.52% (Gürbüz et al, 2017), 41.25%-45.96% (Yıldırım, 2018), 37.50% (Khanjani et al, 2021), 10.81% (Xylia et al, 2021), 17.79%-23.40% (Micić et al, 2021), 26.40%-49.10% (Flamini et al, 2021), 40.10% (Christopoulou et al, 2021, 30.89%-31.61% (Dzięcioł, 2021), 28.97%-32.18% (Elyemni et al, 2022), 32.50%-51.79% (Rathore et al, 2022), 30.26% (Mwithiga et al, 2022), 25.26%-29.15% (Yeddes et al, 2022), 11.86% (Karakaş and Bekler, 2022).…”

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.
