The chemical compositions of the essential oil of the rhizome, leaf and stem of Hornstedtia leonurus Retz., collected from Negeri Sembilan, Malaysia, are reported for the first time. The essential oils were extracted using hydrodistillation and analyzed by gas chromatography (GC-FID) and gas chromatography/mass spectrometry (GC/MS). Seventeen (96.4%), thirteen (89.2%) and nine components (98.8%) were successfully identified from the rhizome, stem and leaf oils, respectively. Phenylpropanoids were found to be the major fraction, with methyleugenol being the most abundant compound in all oils with percentage compositions of 76.4% (rhizome), 80.3% (stem) and 74.5% (leaf).

The essential oil ofBetula pendulaRoth. buds was obtained using both hydrodistillation and microdistillation techniques and their chemical compositions were analyzed using both gas chromatography (GC) and gas chromatography–mass spectrometry (GC-MS). Overall, more than 50 compounds were identified representing 80% and 92% for hydrodistillation and microdistillation, respectively. The main components (by hydrodistillation and microdistillation, respectively) found were α-copaene (12% and 10%), germacrene D (11% and 18%) and δ-cadinene (11% and 15%) in the analyzed essential oils. The microdistillation technique proved to be a useful tool and compliant alternative when compared to hydrodistillation.

Oleogum resins of B. papyrifera, B. neglecta, and B. rivae were collected from northwestern, southern, and southeastern Ethiopia, and their respective methanol extracts and essential oils were extracted and analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The investigation on essential oils led to the identification of 6, 7, and 8 constituents for B. papyrifera, B. neglecta, and B. rivae, respectively. The essential oil of B. papyrifera is mainly characterized by the presence of octyl acetate (57.1–65.7%) and n-octanol (3.4–8.8%). B. neglecta is rich in α-pinene (32.6–50.7%) followed by terpinen-4-ol (17.5–29.9%) and α-thujene (12.7–16.5%), whereas B. rivae was predominated by α-pinene (32.5–66.2%) followed by p-cymene (5.7–21.1%) and limonene (1.1–19.6%). Methanol extracts of the three Boswellia species were found to consist of diterpines (incensole, incensyl acetate and verticilla-4(20),7,11-triene), triterpenes (β-amyrin, α-amyrin, β-amyrenone, and α-amyrenone), nortriterpenes (24-noroleana-3,12-diene and 24-norursa-3,12-diene), and α-boswellic acid. The investigation on the methanol extract showed that only B. papyrifera contains diterpenes and nortriterpenes, whereas B. rivae and B. neglecta consist of only triterpenes. The results indicate that the three Boswellia species were characterized by some terpenes and these terpenoic constituents could be recognized as chemotaxonomical markers for each species.

The essential oil composition from the aerial parts of three Anacardiaceae growing in Bahía Blanca, Argentina was studied by gas chromatography and gas chromatography-mass spectrometry. The essential oils of S. longifolia and S. fasciculata have been studied for the first time. The major constituents were α-pinene (46.5%), β-pinene (15.1%) and α-phellandrene (10.1%) for S. longifolia and limonene (10.9%), β-phellandrene (6.16%) and α-phellandrene (5.6%) for S. fasciculata. The major components of the essential oil of S. areira were limonene (28.6%), α-phellandrene (10.1%), sabinene (9.2%) and camphene (9.2%) differing from the literature data. The essential oils from S. areira and S. longifolia exhibited a high biotoxicity in a brine shrimp assay with Artemia persimilis.

Coriander and cilantro, the fruit and herb of Coriandrum sativum, are popular additives in various cuisines worldwide. The essential oils derived from coriander and cilantro are also popular and have shown some remarkable biological properties and health benefits. In this report, we have analyzed the essential oil compositions of 19 commercial coriander and 28 commercial cilantro essential oil samples by gas chromatography–mass spectrometry (GC–MS) techniques. In addition, 5 coriander and 4 cilantro commercial essential oil samples were analyzed by chiral GC–MS. Commercial coriander essential oil is dominated by linalool (62.2%-76.7%) with lesser quantities of α-pinene (0.3%-11.4%), γ-terpinene (0.6%-11.6%), and camphor (0.0%-5.5%). Commercial cilantro essential oil is composed largely of (2 E)-decenal (16.0%-46.6%), linalool (11.8%-29.8%), (2 E)-decen-1-ol (0.0%-24.7%), decanal (5.2%-18.7%), (2 E)-dodecenal (4.1%-8.7%), and 1-decanol (0.0%-9.5%). The enantiomeric distribution of linalool was 87% (+)-linalool:13% (−)-linalool in both coriander and cilantro essential oils, while α-pinene was 93% (+):7% (−) in coriander, 90% (+):10% (−) in cilantro; and (+)-camphor:(−)-camphor was 13%:87% in both essential oils. Chiral GC–MS analysis was able to detect an adulterated coriander essential oil sample. The data provided in this study serves to establish a baseline for future evaluations of these essential oils as well as a screen for authenticity or adulteration.

The essential oils of Ziziphora clinopodioide Lam. from four different production areas (Banfang ditch; Altay mountains; Tuoli; Terks) were investigated. The oils were extracted by hydro-distillation and analyzed by gas chromatography-mass spectrometry (GC-MS). Seventeen constituents were identified in the essential oil from Banfang ditch, 20 in that from the Altay mountains, 12 in the Tuoli essential oil, and 9 in the Terks sample. The major components of the oils were pulegone (67.6%, 32.5%, 86.4%, and 82.1%) and p-menthanone (14.8%, 43.7%, 3.2%, and 8.2% from the Banfang ditch, Tuoli, Altay mountains, and Terks samples, respectively).

Here we report for the first time hydrodistillation of leaf essential oils from Phebalium squamulosum subsp. verrucosum, P. glandulosum subsp. eglandulosum, P. glandulosum subsp. nitidum and P. glandulosum subsp. angustifolium (Rutaceae: Boronieae). Essential oils were analysed using gas-chromatography/mass spectrometry (GC-MS) and nuclear magnetic resonance spectroscopy (NMR). With the exception of P. glandulosum subsp. angustifolium, all taxa yielded essential oils in relatively high amounts (1–3%, w/w) made up predominantly of 2,6-dimethyloct-7-en-4-one (dihydrotagetone). The essential oil from P. squamulosum subsp. verrucosum contains either (+)-dihydrotagetone ( ee 94–100%) or (-)-dihydrotagetone ( ee 17–18%). Taxonomically, these results support the proposal that P. squamulosum subsp. verrucosum may be specifically misplaced, phytochemically resembling the P. glandulosum complex. Similarly, P. glandulosum subsp. angustifolium phytochemically resembles P. distans or P. longifolium and also appears to be assigned incorrectly to the P. glandulosum group.

The Relationship

The chemical compositions of the essential oils of the fresh and dried leaves of Ipomea pes-caprae from Mauritius were studied for the first time by gas chromatography-mass spectrometry and 70 compounds were identified. The major components were found to be 8-cedren-13-ol (13.0%), (E)-nerolidol (7.0%), guaiol (6.2%), α-cadinol (6.2%) and limonene (6.1%) in fresh leaves and β-caryophyllene (36.6%), α-copaene (8.0%), germacrene D (7.3%), phytol (5.8%), δ-cadinene (5.7%), and α-humulene (5.4%) in the dried leaf samples. The relationship between the anti-hemorrhoidal activity of Ipomea pes-caprae, one of its traditional uses in Mauritius, and the chemical composition of the essential oil samples is also discussed.

The chemical composition of the essential oils of Ziziphora clinopodioides Lam. from the aerial flowering parts, collected during two different years, were obtained by hydrodistillation and analyzed by gas chromatography – mass spectrometry. Forty-five components representing 100% and 94.7% of the total oil were identified. The main constituents of the essential oils were pulegone (72.8 and 35.0%), neomenthol (6.5 and 23.1%), menthone (6.2 and 13.3%), p-menth-3-en-8-ol (1.7 and 3.5%), piperitenone (2.6 and 1.1%) and piperitone (0.7 and 1.2%). A cluster analysis was carried out on the essential oil compositions of Z. clinopodioides.
