The chemical compositions of the essential oils of Salvia potentillifolia (Lamiaceae) were analyzed by GC and GCMS. The oils were obtained by four different methods (hydrodistillation, steam distillation, and two extraction methods) to investigate the effect of temperature on the volatile compounds. In total, 121 components were detected in the various oils. The major compounds characterized were α-pinene (30.2, 31.2, 10.6, and 14.8 %) and β-pinene (15.0, 14.6, 7.6, and 11.4%), respectively. Surprisingly, the percentage concentrations of α-pinene and β-pinene in the hydrodistilled and steam distilled oils were high, even though prepared at high temperature, whereas the contents of both compounds were lower in the essential oils obtained by the extraction methods prepared without added heat. The percentage concentration of 8,13-epoxy-labda-14-en-2-one, a diterpenoid, in the extracted essential oil was 22 times higher than in the hydrodistilled and steam distilled essential oils. However, the concentrations of cis-p-menth-2-en-1-ol was four times, and β-bourbonene and β-caryophyllene two times superior than their percentage concentrations in the hydrodistilled and steam distilled essential oils.

The essential oils of the barks of Croton monteverdensis Huft and C. niveus Jacq. (Euphorbiaceae) from Monteverde, Costa Rica, were isolated by hydrodistillation in yields of 0.03% and 0.10%, respectively. The chemical composition of the oils was determined by GC–MS. The most abundant essential oil components of C. monteverdensis were α-pinene (17.1%), β-pinene (10.5%), and linalool (8.3%), while C. niveus bark oil was made up largely of α-pinene (14.4%), 1,8-cineole (11.6%), and borneol (8.5%). The major components account for the fragrances and are consistent with the traditional medicinal uses of these plants.

Rosmarinus officinalis is among the most abundant medicinal and aromatic plants in Morocco. There are several factors that influence the yield of quality and quantity of essential oils of this plant. This work focuses on the study, characterization and comparison of the chemical composition of essential oils of Rosmarinus officinalis. The raw material studied is originally from the central part of northern Morocco (Skoura M'Daz region, Eastern Middle Atlas). The essential oils of rosemary were obtained by three different extraction methods : DA: Artisanal distillation, the essential oils were obtained directly from small cooperatives using a very traditional (nonindustrial) method and based on the technique of Steam distillation ; DI: Industrial distillation which is also based on Steam distillation; DC: hydrodistillation by clevenger apparatus Laboratory. The physicochemical characterization of essential oils focuses on the search for the yield of % essential oil with regard to the dry rosemary biomass, density, refractive index and rotatory power. The chemical analyzes were carried out by gas chromatography (GC), they identified 11 components representing more than 99.64% of the essential oil and indicate that the chemotype is 1.8 cineole and is varied according to the method (DI: 48.83%, DA: 41.28% and DC: 51.77%). In conclusion we have shown a quantitative and qualitative loss of essential oils due to the extraction method of essential oils, which has direct repercussions on the economy of rural Morocco and consequently on their sustainable development.

Agarwood and agarwood essential oils are commodities with great commercial value. In Vietnam, the agarwood industry has been growing, with more than 10,000 ha of forest land reserved for the cultivation of Aquilaria crassna, an agarwood-producing tree. The aim of this study was to present a hydrodistillation process to recover agarwood essential oil and to compare chemical compositions of agarwood samples harvested from various locations in Vietnam. Three agarwood samples representing products from A. crassna trees cultivated in the provinces of Bac Giang and Khanh Hoa, and on the Phu Quoc island (Kien Giang province) of Vietnam were subjected to hydrodistillation, resulting in essential oil yields of 0.32%, 0.27%, and 0.25% (w/w), respectively. Using GC–MS analysis, a total of 44 volatile compounds were identified in the obtained oils. Most of the constituents were oxygenated sesquiterpenes and had been previously found in other agarwood oil samples. Notable compounds of other chemical classes were aromatics and fatty acids. The three oil samples showed a common volatile profile, which is characterized by the dominance of eremophilane, agarofurans, and eudesmane sesquiterpenes, while vetispirane and guaiane sesquiterpenes were found in smaller quantities. Desired compounds, such as neopetasane (7.47–8.29%), dihydrokaranone (2.63–3.59%), β-agarofuran (3.04–6.18%), and agarospirol (2.98–3.42%), were present in substantial quantities, suggesting that the essential oils could be commercialized as fragrant materials of high value.

Essential oils were extracted from biomaterials of root bark, stem bark, twigs, leaves and flowers fromMagnolia sieboldiiby the means of steam distillation. Their chemical compositions of these essential oils were analyzed by GC-MS method and their flavor properties were evaluated based on the basic media of cold creams. The results showed that the highest yield of essential oils belonged to the essential oil from root bark and the lowest belonged to that from leaves; As to flavor, the parts of leaves and flower are more suitable for exploiting cosmetic products; Twigs, flowers and leaves belonged to the same cluster by Hierarchical cluster analysis on chemical components from these essential oils. The essential oil from leaves should be further exploited due to its good flavor for cosmetic products and a kind of newable natural resources, although this essential oil had lower extraction yeilds.

Solvent-free microwave extraction (SFME) is a combination of microwave heating and dry distillation performed at atmospheric pressure without the addition of water or organic solvents that has been proposed as a green method for the extraction of essential oils from aromatic and medicinal herbs. In this work, SFME and the conventional techniques of steam distillation (SD) and hydrodistillation (HD) were compared with respect to the extraction and antioxidant and antimicrobial activities of Thymus mastichina essential oil. The main constituent of essential oils obtained using different methods was 1,8-cineole (eucalyptol). The results showed that the essential oils extracted by means of SFME in 30 min were quantitatively (yield) and qualitatively (aromatic profile) similar to those obtained using conventional HD over 120 min. In addition, SFME generates less waste and less solvent, consumes less energy, and provides a higher yield for a shorter extraction time, which is advantageous for the extraction of the T. mastichina essential oil compared to SD. The antioxidant and antimicrobial activities of the T. mastichina essential oil obtained from either SFME or conventional extraction methods (SD or HD) showed a similar pattern. Large-scale experiments using this SFME procedure showed a potential industrial application.
