In the present work, chemical composition of essential oils of rosemary (Rosmarinus officinalis L.) from various geographic origins (Kerman and Lalehzar) were determined by GC/MS. Rosemary leaves oil was isolated by hydrodistillation. The 49 components were identified in Lalehzar oil and 31 components were identified in Kerman oil. The hydrodistillation of Lalehzar oil was found to be rich in-pinene (43.9%), 1, 8-cineole (11.1%), camphene (8.6%),-myrcene (3.9%), broneol (3.4%), camphor (2.4%) and Verbenol (2.3%). 31 components were identified in hydrodistillation of Kerman oil and main component as follow;-pinene (46.1%), 1, 8-cineole (11.1%), camphene (9.6%), camphor (5.3%), sabinene (4.6%),-myrcene (3.9), broneol (3.4%), bornyl acetates (2.8%), verbenone (2.3%) and linalool (2.1%).
Essential oil from fresh and dried Rosemary cultivated in Lam Dong province, Vietnam
IOP Conference Series: Materials Science and Engineering, 2019
Rosemary essential oil has been widely used in folk medicine for treatment of anxiety, memory deficit and cancer thanks to its high antioxidant activity and antibacterial properties. Composition of rosemary essential oil largely depends on the geographical position of the cultivated plant and conditions of the extraction process. In this study, fresh and dried rosemary leaves were used for extraction of essential oil using hydrodistillation method. The extraction performance, composition and antioxidant activity of the essential oil were measured. The oil yield for dried leaves (1.2 ml/g) is significantly lower than that for fresh leaves (3.16 ml/g). However, the difference on chemical profile and antioxidation activity of the two oil samples was indistinguishable. The most remarkable finding was the presence of Levoverbenone at very high concentration in rosemary essential oil, accounting for 10.87% and 12.12% of the oil sample extracted from fresh and dried leaves respectively.

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 anti...
Physico-chemical evaluation of Rosmarinus officinalis L. essential oils
Brazilian Archives of Biology and Technology, 2005
Nineteen samples of Rosmarinus officinalis were extracted by steam distillation in a pilot plant and evaluated in terms of chemical compositions and physico-chemical characteristics. The volatile oil yields ranged from 0.37% (1999 harvest) to 0.49% (1998 harvest). Twenty components were identified in the oils. The major components were alpha-pinene (40.55 to 45.10%), 1,8-cineole (17.40 to 19.35%), camphene (4.73 to 6.06%) and verbenone (2.32 to 3.86%). The physico-chemical parameters averaged 0.8887 g/cm 3 for specific gravity, 1.4689 for refractive index, and +11.82° for optical rotation, and there were no significant variations in either the chemical or physicochemical data in the different years.

The Lamiaceae is a large family, rich in aromatic species and used as culinary herbs, folk medicines, fragrances, etc. Many species of this family possess essential oils secreted by glandular trichomes. In the family Lamiaceae, there are two main types of trichomes: peltate and capitates. Studies of these glandular trichomes comprise morphological, structural, and histochemical analysis. Rosmarinus officinalis L. is an evergreen, perennial shrub native to the Mediterranean Sea and areas [1]. R. officinalis L., is a diploid (2n = 2x = 24) and allogamous species. It is the most exploited species for its essential oil and phenolic biological properties . These variations are mostly correlated to differences in the chemical composition of the oils according to regions . Dried rosemary leaves are used as seasoning for soups, meat, fish, and poultry. The oil extracted from this plant is used in food products, perfumes, and cosmetics such as soaps, creams, deodorants, hair tonics, and shampoos. The plant and extracts possess antibacterial and antioxidant activity and are considered as a good source of nectar for insects. As a medicinal plant, rosemary has been used as an external stimulant and as a relaxant of nervousness, muscle spasms, and headaches. It has also been used in the treatment of cancer and is categorized today as a therapeutic emmenagogue . It has been used as an analgesic, antirheumatic, carminative, cholagogue, diuretic, expectorant, and antiepileptic. It has effects on human fertility and is hepatoprotective and antimutagenic . The antioxidant activity of rosemary extracts has been associated with the presence of several phenolic diterpenes such as carnosic acid, carnosol, rosemariquinone, and rosemaridiphenol, which break free radical chain reactions by hydrogen donation . Various extracts of rosemary are used for retarding lipid oxidation in various foods .

Plant Based Natural Products (PBNPs) have contributed to the development of many drugs for diverse indications. Worldwide interest in use of plants based natural products (PBNPs) has been growing, and its beneficial effects being rediscovered for the development of new drugs. Literature survey on indigenous traditional knowledge bestows ethnopharmacological potentials of PBNPs, which has inspired current research in drug discovery; PBNPs provide baseline for the development of novel drug leads against various pharmacological targets. Studies report that rosemary essential oil (REO) extracts in particular show biological bioactivities such as hepatoprotective, antifungal, insecticide, antioxidant and antibacterial. It is well known that the biological properties in rosemary are mainly due to phenolic compounds. However, their application is limited because of their odor, color and taste. Owing to the widespread applications of phytocompounds in REO - GCMS was performed. GCMS analysis detected 22 compounds of which 6 compounds were in abundant. Their ADMET properties were evaluated to ponder its application

In this research, essential oil (EO) compositions of the dried and fresh aerial parts of Rosmarinus officinalis cultivated in the reearch field in Selcuk University Medicinal and Aromatic Plants Department Area in Konya and collected from Mersin was investigated. Material and Methods: EO was distilled by using Clevenger type apparatus for 3 h and the chemical compositions were detected in GC-MS. Results: Although, the oil yields of the collected rosemary was determined to be 0.4 ml (in fresh) and 0.6 ml (in dried) aerial parts, the yields of the cultivated plants for fresh and dried parts were 0.32 ml (in fresh) and 0.9 ml (in dried), respectively. In this research the differences with respect to composition and components were determined between the cultivated and collected plants. On the other hand, in this study, it was also determined that the EO compositions varied with respect to be fresh or dry of the plant parts. While there were 67 and 55 of EO compositions were observed in the fresh and dried parts of the collected marjoram, respectively; in the cultivated plants there were 46 (in fresh) and 79 (in dried) components detected. Conclusion: In this study, it was observed that the major EO compositions were camphor, 1.8-cineole, borneol, α-pinene, linalool, verbenone, bornyl acetate, limonene and camphene. The objective of the study to detect the differences between the EO compositions varied according to be the plant fresh or dry and collected or cultivated.
