Essential Oil Production

<p>Tuberose flower wastes are potentially used as raw materials for producing essential oils. Enfleurage method was used in the extraction process of the flower wastes. Petroleum ether and hexane were used as solvents during the extraction, while snow white (white butter) was used as fat during the enfleurage process. The enfleurage process was done for 4 days with replacement of flowers every 24 hours. It was found that petroleum ether gave higher yield than hexane (i.e. 7.07%). However, compared with hexane, petroleum ether was still existed on the produced essential oil.</p><p><strong>Keywords</strong>: enfleurage, hexane, petroleum ether, tuberose flower, waste </p>

Essential Oil Production

This article reveals that essential oil production is a complex system with a large number of economic ties arising in the process of growing and processing as well as distribution of products made from essential oils raw materials. Multileveled manufacturing process of essential oils products requires coordination of all the elements to reduce costs in the entire supply chain. It is proposed to use mathematical modeling of the supply chain based on the method of main faces, which allows to take into account the specifics of the problem and makes it possible to use a variety of combinatorial and heuristic algorithms.

Essential Oil Production

Alpinia zerumbet (Pers.) B.L. Burtt. & R.M. Sm is an important perennial ginger plant in the tropics with various uses as foods, dietary supplement, cosmetics, essential oil production and traditional medicines. In this study, essential oils, phenolic acids, fatty acids, kavains, total phenols and antioxidant activity in A. zerumbet plants exposed to UV-C were investigated. Number and weights of essential oils increased rapidly from 1 to 3 days of exposure. Major extend of essential oils was recorded in methyl cinnamate and followed by benzyl acetone. The correspondence to the accumulation of palmitic acid was 15 folds, in contrast to the strong reduction of stearic quantity was 10 folds at 3 days of treatment. Changes in chemical components and antioxidant capacity in A. zerumbet are differed reversely between the exposure of UV-C and heavy toxic chemicals. The exposure of UV-C is beneficial for the increasing of essential oil production in A. zerumbet.

Essential Oil Production

The amount and chemical composition of essential oils are crucial for the modulation of the flavor, scent and therapeutic properties of aromatic and medicinal plants. The aim of this study was to evaluate the effects of phenology and weather conditions on the essential oil yield obtained from the aerial parts of Salvia lavandulifolia Vahl. Besides, we tried to carry out an approach to the chemical composition at the time of full bloom. Essential oil production of several accessions was monitored throughout the whole phenological cycle, both, at the original location growing wild and at the experimental plot as cultivated plants. Local pedoclimatic conditions seem to be crucial for the plant essential oil production. Our results showed high conditioning rates from both yearly climatic conditions and developmental stage of the plants. Maximum yield production was reported at the full seed maturation stage (average 1.74%) and after a slight dry period (average 2.16%). Phytochemical differences were maintained when plants were forced to grow under common pedoclimatic conditions. Thereby, essential oil analysis showed some populations formed by clearly distinct individuals while others had more homogenous plants. Compounds such α-pinene, β-pinene + myrcene, limonene, 1,8-cineol, camphor and β-caryophyllene were the main compounds of the essential oils of S. lavandulifolia.

Prasium majus L. (Labiatae, Lamioideae) is considered a typical non-aromatic plant. In this work we examined the glandular trichomes present on leaves and inflorescences and the essential oils of plants growing along the Tuscan coast of Italy. The micromorphological study evidenced different types of trichomes responsible for the essential oil production. The essential oil compositions of leaves and flowers were analyzed by GC/MS and are here reported.

Abstract Background Essential oil of Rosa × damascena Herrm. is one of the most valuable and important raw materials for the flavor and fragrance industry. The cultivation of this plant has ancient origins, and Kashan was one of the first mountainous regions of Iran dealing with the cultivation of R. × damascena. In this study, both chemical composition and antimicrobial activity of different rose essential oils obtained from five mountainous areas of Kashan region (Maragh, Qamsar, Sadeh, Javinan, and Kamoo) has been investigated along with the influence of the environmental conditions on these properties. Results Results showed that yield and chemical composition of essential oils obtained from Rosa × damascena were significantly affected by the collection area. In particular, the yield of oils varied from ~0.08 to ~0.132% and citronellol (36.70-9.18%), geraniol (12.82-0.47%), nonadecane (22.73-10.36%), heneicosane (31.7-11.43%), and 1-nonadecene (6.03-3.93%) have been detected as main compounds in all the plants collected, but at different concentrations depending on the collection area. The best fragrance and the highest yield were found in the oil from Kamoo area. Similarly to the chemical composition, the antimicrobial activity of the essential oils was affected by their origin, and essential oil obtained from plants collected from Kamoo area disclosed the highest antibacterial and antifungal efficacy. Its inhibition halos were 17.33±0.58 mm against Aspergillus brasiliensis, 15.67±0.58 mm against Staphylococcus aureus, and 12.33±0. 58 mm against Streptococcus pyogenes. Essential oils of R. damascena were also effective against Gram-negative Pseudomonas aeruginosa and they had a MIC value of 62.50 μg/mL irrespective of the collection area (except the oil from Javinan area). On the contrary, the highest antifungal power against Candida albicans yeast was reached using the essential oil obtained from plants collected in Javinan region (MIC and MBC ~62.50 μg/mL). Conclusions Overall results underline the influence of environmental conditions of the different areas of Kashan region, on the chemical composition of and antimicrobial activity of the essential oils of Rosa × damascena. In addition, results disclosed that Kamoo seemed to be the most suitable area for the competitive cultivation of R. × damascena to the intensive production of aromatic flower oil and natural antimicrobial essential oils.
