Turmeric has been recognized as a pharmaceutical crop. It is valuable primarily for essential oil and curcumin content. Chemical composition of the essential oils obtained from the rhizome of turmeric was determined by GC/MS technique. More than 75 compounds were detected and 67 of them were identified. They accounted for 98.59% of essential oil. The essential oil contained 15 monoterpenes (5.58%), 43 sesquiterpenes (84.37%) and 10 nonterpenic components (8.64%). The major constituents were ß-turmeron, a-turmeron, Epi-a-patschutene, ß-sesquiphellandrene, 1,4-dimethyl-2-isobutylbenzene, (±)-dihydro-ar-turmerone, zingiberene, E-a-atlantone and (-)-caryophyllene oxide. Thin layer chromatographic finger printing and quantitative determination of phenolics in acetone extract of commercially available turmeric samples were carried out using Folin-Ciocalteu colorimetric method. Gallic acid was used as the standard for the estimation of phenolics. All the investigated turmeric extracts contained relatively high amount of phenolics.Nepal Journal of Science and Technology Vol. 16, No.1 (2015) pp. 87-94

ABSTRACT: Campomanesia adamantium is a native fruit species of the Cerrado and is used in food and medicines and as bee pasture. The chemical composition of essential oils obtained from plants of the same species have varying constituent proportions due to the influence of extractive factors, environmental, genetic and ontogenetic. This study aimed to identify the influence of hydrodistillation time on the content and chemical composition of essential oil extracted from the leaves of C. adamantium . Treatments consisted of five extraction times (1, 2, 3, 4, and 5h) using Clevenger with five replications in a completely randomized design. It was observed that after two hours of hydrodistillation, the essential oil content remains constant. Regarding the chemical constituents of essential oil, variation of the proportions of the compounds tested occurred at all hydrodistillation times. The compounds spathulenol oxygenated sesquiterpenes and caryophyllene oxide were the majority in the five hydrodistillation times.

The essential oils of Blainvellea rhomboidea (Asteraceae) were obtained by hydrodistillation and analyzed by GC/MS and GC/FID. Initially, the essential oil from the aerial parts was investigated. From the 18 identified components, 5-indanol (14.5%) followed by p-cymen-8-ol (10.1%), β-caryophyllene (9.6%), caryophyllene oxide (9.6%), limonene (8.6%), terpinolene (7.8%), and spathulenol (7.7%) were the major constituents. The oil was tested against seven bacterial strains and the results showed significant antimicrobial activity. As a consequence, the essential oils from leaves and from flowers were analyzed separately. The major constituents of the leaf oil were terpinolene (21.2%), β-caryophyllene (19.2%), spathulenol (9.1%), caryophyllene oxide (7.4%), and bicyclogermacrene (7.1%), while the oil of the flowers contained terpinolene (28.1%), 5-indanol (16.3%), p-cymen-8-ol (15.3%) and limonene (14.7%) as prevalent compounds. The oils were tested against the same bacterial strains and the flower oil was the more active. These results indicated that the components of the essential oil from flowers seem to be responsible for the activity.

The restinga is an Atlantic Forest ecosystem characterized by tree, shrub, and herb species that are rich sources of essential oils. In this study, we aim to quantify the essential oil content and determine the chemical constituents of fresh leaves of 14 plant species in a restinga stretch in southern Brazil. Essential oils were obtained by hydrodistillation in a Clevenger-type apparatus and analyzed by gas chromatography coupled to mass spectrometry. Campomanesia reitziana, Cortaderia selloana, and Sophora tomentosa had no essential oils. Total essential oil content ranged from 0.01% (Mikania involucrata) to 1.56% (Varronia curassavica). In total, 60 chemical constituents were identified, representing between 46.2% and 96.5% of the chemical composition of the essential oils. Limonene was the common constituent in all species in which the essential oils were present. The major constituents were ar-curcumene (15.1%) and cis-chrysanthenol (14.2%) in Ambrosia elatior; benzyl benzoate (43.5%) and benzyl salicylate (23.7%) in Aniba firmula; caryophyllene oxide (35.7%) and spathulenol (10.6%) in Austroeupatorium inulaefolium; spathulenol (19.8%) and caryophyllene oxide (14.0%) in Baccharis spicata; caryophyllene oxide (16.3%) in Eugenia astringens; curzerene (30.0%), limonene (13.0%), and germacrone (11.9%) in Eugenia uniflora; caryophyllene oxide (17.1%) and ledol (11.3%) in Lantana camara; caryophyllene oxide (27.7%) and limonene (12.7%) in M. involucrata; 1,8-cineole (19.8%) in Psidium cattleianum; limonene (10.2%) in Schinus terebinthifolius, and allo-aromadendrene (15.2%) in V. curassavica. We expect that our results can assist in selecting species of potential interest for herbal, phytotherapeutic, and cosmetic products.

The composition of the essential oils (EO) from leaves and rhizomes of Hedychium coronarium was analyzed both by gas chromatography and gas chromatography-mass spectroscopy. Thirty and thirty-nine compounds were identified, respectively, in the oils from leaves and rhizomes, representing 88% and 86.1% of the whole compositions. Caryophyllene oxide is the major component in rhizomes while 1,8-cineole predominates in leaves oil. Essential oils and major components were tested for trypanocidal activity using procyclic forms of Trypanosoma brucei (427 and 29-13 strains). The cytotoxicity index (CI50), using the MTT colorimetric method, showed that essential oils and 1,8-cineole were inactive (>100 μg·mL−1. Nevertheless, caryophyllene oxide revealed a remarkable activity against both T. brucei strains (CI50 = 65.77 μg·mL−1 and 24.53 μg·mL−1, resp.), and the synergism between caryophyllene oxide plus pentamidine (1 : 1, v/v) highly increased the trypanocidal activity (<1.0 μg·mL−1).

The chemical composition of four essential oils of four species of sage (Salvia officinalis L., Salvia pratensis L., Salvia glutinosa L. and Salvia aethiopis L) are examined by GC-FID and GC-MS analysis. The presence of some components in the essential oil (mono- and sesquiterpene) determines the pharmacological effects and therapeutical application of a plant species. Salvia officinalis L. gives the highest yield of oil (1.1 %), while the lowest is in Salvia pratensis L. (0.1 %). The investigations included the determination of the antimicrobic activities of the essential oils by the diffusion method and the oil of Salvia pratensis L. proved to have the highest activity.

The present study was dedicated to the study of the chemical composition and the antioxidant activity of the essential oils from the sawdust of Tetraclinis articulata in Morocco (from Khemisset region). The yield of the essential oil obtained by hydrodistillation from sawdust was 2.19%. The determination of the chemical composition of Tetraclinis articulata essential oils (TAEO) was carried out by GC-SM analysis. The results that 22 volatile compounds were identified in the sawdust part of T. articulata, representing 87.25% of the total composition. The study of TAEO antioxidant activity was assessed by three different methods: the trapping of free radical DPPH, bleaching assay ABTS, and the reduction of iron (FRAP). The results of DPPH test showed that TAEO (IC50=0.0144 mg/mL) has a very interesting antioxidant activity compared to the ascorbic acid used as reference (IC50=0.0184 mg/mL). These results reveal promising prospects for the future exploitation of TAEO as a potential source of natural antioxidant substances that may be used for future investigations.

Artemisia scoparia Waldst.et Kit. is an annual or biennial plant, widely spread on Transbaikal Territory. We have attempted to identify the leading factor affecting on the composition of essential oil in this article. Raw materials were collected during field works in 2014-2016 on the territory of Buryatia and on Transbaikal Territory. Essential oil was obtained by hydrodistillation method from air-dried raw materials. The chemical composition of the oil was analyzed by chromatography-mass spectrometry. According to the composition of the components the studied oils referred to a chemotype containing monoterpene and sesquiterpene compounds as the main components. β-Myrcene, limonene, α- and β-pinenes, α- and β-farnesenes, caryophyllene, α-copaene, spathulenol were identified almost in all samples except one, and p-cymol, γ-terpinene, humulene, caryophyllene oxide were found in most of them.The variety of identified components of oils was associated with the secondary transformation of terpenes, the components of oils were representatives of 19 structural types of compounds. The composition of essential oils of Artemisia scoparia from Transbaikal Territory was characterized by a high content of sesquiterpene compounds.The humidity mainly influenced on the composition of essential oils. Mostly accumulation of sesquiterpene compounds occurred in essential oils of plants growing in ecotopes with sufficient humidity, and monoterpenes - in places with less humidity.
