Exhaustive Study

The essential oil composition of the aerial parts of four populations of Eryngium campestre has been analyzed by GC and GC/MS. Samples growing in different types of soil were gathered at the same phenological state. A total of 84 compounds have been identified from the different samples under analysis. Qualitative and quantitative differences were found between inflorescences (I) and stems and leaves (SL) of the different populations. The main constituents of the inflorescences were identified as germacrene D (30.3-40.3%), β-curcumene (0.7-22.2%), myrcene (3.0-21.7%) and ( E)-β-farnesene (0.1-19.0%). The type of soil seemed to exert an influence on the chemical composition of the oils of this species. Whereas high concentrations of myrcene were found in the populations growing in acid soil, its concentration was significantly lower in the alkaline populations. β-Curcumene concentration was higher in the populations growing in alkaline soil and was practically absent from the acid soil population. Regarding the stems and leaves, only germacrene D (31.1-42.4%) and myrcene (0.5-23.15) were considered as main constituents, their composition not being affected by the type of soil. However, terpenoid distribution was clearly influenced by the soil, with the population growing in acid soil containing a greater amount of monoterpenes than that of the population growing in alkaline soil. A more exhaustive study needs to be carried out in order to confirm if the biosynthesis of these compounds could be influenced by the availability of Ca2+ in the soil.

This study reports the essential oil composition and headspace volatiles profile of Achillea coarctata Poir. from Serbia. The inflorescences, stems and leaves, and the aerial parts of A. coarctata were analyzed separately. Germacrene D, α-terpineol and 1,8-cineole were the main constituents of the aerial parts essential oil; 1,8-cineole, cis-cadin-4-en-7-ol and α-terpineol were the most dominant compounds in the inflorescence essential oil, while the most abundant components in the stem and leaf oil were germacrene D, cis-cadin-4-en-7-ol and ledol. The percentages of monoterpenoids and sesquiterpenoids in the aerial parts were the same, while there were differences in distribution of these compound classes in inflorescence and stem and leaf essential oils. The major components of the headspace volatiles were the same for aerial parts, inflorescence and stem and leaves: 1,8-cineole, β-pinene and α-pinene.

The essential oils from fresh aerial parts of Monticalia greenmaniana (Hieron) C. Jeffrey (Asteraceae) collected in March, were analyzed by GC/MS. Oil yields (w/v) of 0.1% (flowers), 0.07%, (stems) and 0.1% (leaves) were obtained by hydrodistillation. Thirteen, sixteen and eighteen components, respectively, were identified by comparison of their mass spectra with those in the Wiley GC-MS Library data base. The major components of the flower and stem oils were 1-nonane (38.8% flowers; 33.5% stems), α-pinene (29.0% flowers; 14.8% stems) and germacrene D (15.6% flowers; 18.6% stems). However, in the leaf oil, germacrene D was observed at 50.7%, followed by β-cedrene at 8.4 %. The leaf essential oil showed a broad spectrum of antibacterial activity against the important human pathogenic Gram-positive and Gram-negative bacteria Staphylococcus aureus (ATCC 25923), Enterococcus faecalis (ATCC 19433), Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853) and Klebsiella pneumoniae (ATCC 25955) with MIC values ranging from 75 to 6000 ppm.

Hyptis colombiana is an aromatic shrub native to the Colombian and Venezuelan Andes. Aerial parts were collected in Mérida State at about 3100 m above sea level in February 2005, and May and October 2006. The essential oil was found to contain germacrene D and β-caryophyllene as main constituents (about 50%). The February 2005 and October 2006 oils were found to have antibacterial activity against Staphylococcus aureus, but not the May 2006 oil, probably due to the lack of some minor constituent.

Heracleum lasiopetalum belongs to the Apiaceae family and is native to Iran. The fruits and seeds of the herb are used as spices and food additives. The genus has significant pharmacological activities. In order to study the phytochemicals of H. lasiopetalum, aerial parts of the plant were conducted to a separation process. Different chromatographic techniques were employed for the purification of its natural products. The chemical structure of the isolated metabolites was determined using spectroscopic methods such as NMR and IR as well as elemental analysis. Moreover, the essential oil composition of roots and aerial parts of the herb were characterized using GC-MS analysis. The purified compounds were elucidated as beta-sitosterol (plant steroid) and suberosin (coumarin). Identification of essential oil composition showed that 17 and 12 volatile compounds were present in the aerial parts and roots of the herb, respectively. Germacrene D, falcarinol, farnesol, and octanal were found as the major components. Findings showed that H. lasiopetalum contains important natural products such as steroids, coumarins, monoterpenoids, and sesquiterpenoids. According to its bioactive products, this herb could be considered for more applications in the cosmetics and pharmaceutical industries.

Abstract- The essential oil composition from the aerial parts of Ormenis africana (Asteraceae), an endemic species from Morocco, has been investigated by GC/MS. A total of 31 compounds were identified, representing 77%. After fractionation by column chromatography, the main compound was isolated and its structure elucidated by NMR spectroscopy. The essential oil was dominated by oxygenated compounds with spathulenol (45.8%) followed by camphor (7.1%), -cadinol (5.9%) and -bisabolol (5.9%) as the main compounds. This oil can be classified as spathulenol-type according to its spathulenol content. In vitro the antibacterial activity of the whole essential oil against three Gram positive (Bacillus cereus, Enterococcus faecalis, Streptococcus C) bacteria and three Gram negative (Proteus vulgaris, Escherichia coli, Pseudomonas aeroginosa) bacteria, showed significant results. Keywords: Asteraceae, Ormenis africana, Essential oil, Spathulenol, Antibacterial activity.

The leaf essential oils of five species of Beilschmiedia from Monteverde, Costa Rica (Beilschmiedia alloiophylla, B. brenesii, B. costaricensis, B. tilaranensis, and an undescribed Beilschmiedia species “chancho blanco”) have been obtained by hydrodistillation and analyzed by GC-MS in order to discern the differences and similarities between the volatile chemical compositions of these species. The principal constituents of B. alloiophylla leaf oil were germacrene D (18.9%), cis- and trans-β-ocimene (18.8% and 9.3%, respectively), α-pinene (11.8%), and bicyclogermacrene (9.1%). The leaf oil of B. brenesii was composed largely of the sesquiterpenes germacrene D (19.3%), β-caryophyllene (13.4%), α-copaene (9.0%), α-humulene (8.1%), and δ-cadinene (5.8%), and the carbonyl compounds 2-undecanone (12.8%), trans-2-hexenal (8.8%), and 2-tridecanone (3.8%). α-Bisabolol (72.1%) dominated the leaf oil of B. costaricensis, while B. tilaranensis had germacrene D (54.9%), β-caryophyllene (14.8%), and δ-cadinene (5.1%) as major components. Beilschmiedia “chancho blanco” leaf oil was composed largely of β-caryophyllene (16.6%), bicyclogermacrene (14.1%), and α-pinene (12.1%).

The essential oils from the different parts [inflorescences (E.a.I), stems + leaves (E.a.SL) and roots (E.a.R)] of E. aquifolium Cav. gathered in Cádiz (Spain), have been extracted by steam distillation and analyzed by gas chromatography and gas chromatography coupled to mass spectrometry. Quantitative and qualitative differences have been found between the analyzed plant parts. A total of 107 compounds have been identified. The main constituents were germacrene D (30.3%) and sesquicineole (26.7%) for E.a.I fraction, germacrene D (46.0%) and myrcene (13.8%) in the E.a.SL, while E.a.R showed phyllocladene isomer (63.6%) as a unique major compound. The percentage composition of the other constituents was lower than 5.5% in all the analyzed fractions. In agreement with other Eryngium species, no specific compound could be used as a marker for the chemotaxonomy of E. aquifolium. However, similarities in volatile composition were found between E. aquifolium and other species growing under similar environmental conditions. As far as we know, this is the first report on the essential oil of this species.
