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.

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.

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.

<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

Aniba canelilla (H.B.K.) Mez. is a tree species from Amazon that produces essential oil. The oil extraction from its leaves and stems can be an alternative way to avoid the tree cutting for production of essential oil. The aim of this study was to analyse factors that may influence the essential oil production and the biomass of resprouts after pruning the leaves and stems of A. canelilla trees. The tree crowns were pruned in the wet season and after nine months the leaves and stems of the remaining crown and the resprouts were collected, in the dry season. The results showed that the essential oil yield and chemical composition differed among the stems, leaves and resprouts. The stems' essential oil production differed between the seasons and had a higher production in the resprouting stems than the old stems of the remaining crown. The production of essential oil and leaf biomass of resprouts were differently related to the canopy openness, indicating that light increases the production of the essential oil and decreases the biomass of resprouting leaves. This study revealed that plant organs differ in their essential oil production and that the canopy openness must be taken into account when pruning the A. canelilla tree crown in order to achieve higher oil productivity.
