Myristica fragrans (f. Myristicaceae) seeds are better known as a spice, but their chemical compounds may have a pharmacological effect. The yield of their composition of extracts and essential oils differs due to different methodologies. The aim of this study was to evaluate an excipient material—magnesium aluminometasilicate—and to determine its influence on the qualitative composition of nutmeg extracts and essential oils. Furthermore, we wanted to compare the yield of essential oil. The extracts were prepared by maceration (M) and ultrasound bath-assisted extraction (UAE), and the essential oil—by hydrodistillation (HD). Conventional methods (UAE, HD) were modified with magnesium aluminometasilicate. The samples were analyzed by gas chromatography-mass spectrometry (GC-MS) method. From 16 to 19 chemical compounds were obtained using UAE with magnesium aluminometasilicate, while only 8 to 13 compounds were obtained using UAE without an excipient. Using our conditions and plant material, for the first time eight new chemical compounds in nutmeg essential oil were identified. Two of these compounds (γ-amorphene and cis-α-bergamotene) were obtained with the use of excipient, the other six (β-copaene, bergamotene, citronellyl decanoate, cubebol, cubenene, orthodene) by conventional hydrodistillation. Magnesium aluminometasilicate significantly increased the quantity of sabinene (from 6.53% to 61.42%) and limonene (from 0% to 5.62%) in essential oil. The yield of the essential oil from nutmeg seeds was significantly higher using magnesium aluminometasilicate; it increased from 5.25 ± 0.04% to 10.43 ± 0.09%.

Essential oil is a hydrophobic concentrated liquid which contains volatile aroma compounds from plants. Bambusa vulgaris grows widely in the tropical and subtropical regions and has been reported to have different ethnomedicinal values such as antimalaria and antioxidant. It is also known to be an ornamental plant. The essential oil was extracted from both the fresh and dried leaves of Bambusa vulgaris by hydrodistillation method using a Clevenger apparatus. The chemical constituents of the essential oils were characterized using gas chromatography and gas chromatography-mass spectrometry. The essential oils obtained are colourless with an herbal odour giving a yield of 0.64 w/w for the fresh sample and 1.08 w/w for the dried sample. A total of thirty-nine (39) compounds were identified from the essential oils of both samples. The major constituents in the fresh leaves were 3-aminodibenzofuran (19.2%), ?-ocimene (11.1%), undecane (9.6%), tridecane (8.6%), [3,2-b] pyridin-6-octahydropyrano (7.1%), 2-mono laurin (6.9%) and vinyl decanoate (5.9%). Prominent compounds of the essential oil in the dried leaves were chlorophenoxymethylenimino sulfur pentafluoride (74.5%) and 2,2,6,6-tetramethyl-3,5-heptanedione (17.3%). Undecane, tridecane, hexadecane and octadecane were found both in the fresh and dried leaves. The chemical constituents of the essential oils from Nigeria Bambusa vulgaris were reported in this study for the first time to the best our knowledge and this could be useful in aromatherapy.

Essential oils have emerged as viable alternatives to synthetic insecticides for control of mosquito-borne pathogens. The leaf essential oils of eight species of Premna (Lamiaceae) growing in central Vietnam have been obtained by hydrodistillation and analyzed by gas chromatography–mass spectrometry. Sesquiterpene hydrocarbons dominated most of the Premna essential oils, with the notable exception of Premnamekongensis from Ngoc Linh Nature Reserve, which had α-pinene as the major component. Larvicidal activities against Aedes aegypti have been determined and all of the Premna essential oils showed larvicidal activity with 24-h LC50 < 65 μg/mL. The leaf essential oils of Premnacambodiana from Chu Mom Ray National Park and Premnamekongensis from Ngoc Linh Nature Reserve showed the best larvicidal activities with 24-h LC50 of 16.8 and 18.0 μg/mL, respectively. The essential oil compositions and larvicidal activities of P. cambodiana, Premna flavescens, Premnamaclurei, P. mekongensis, and Premnapuberula are reported for the first time. Although the larvicidal activities of Premna leaf essential oils are promising, the essential oil yields are relatively low (0.10–0.25%).

Nutmeg Essential Oil

Myristica fragrans Houtt., commonly known as nutmeg, is an Indonesian indigenous dioecious evergreen tree which contains 5-15% volatile oil. The oil is usually produced from the seed or mace.  Nutmeg oil has been extensively utilized in aromatherapy, natural medicine, and the perfume industry. This article provides an overview of the chemical compounds, biological potency, and toxic effects of nutmeg essential oil compiled from recent literature (2000–2020). Nutmeg oil mainly comprises monoterpenes and phenylpropanoids. Several reports on gas chromatography-mass spectrophotometry analysis of nutmeg oil showed that there were 27–38 chemical constituents detected at various concentrations. Many secondary metabolites of nutmeg oil reported to show biological activities that possibly substantiate its utilization in natural medicine. Numerous studies reported the biological activities of this volatile oil such as antioxidant, analgesic, antiinflammation, anticonvulsant, antibacterial, antiparasitic, insecticidal, and anticancer activity. But large intake of nutmeg oil could cause intoxication which is shown through symptoms in cardiovascular, central nervous system, anticholinergic, and local effects in the stomach. These symptoms are mainly attributed to the effect of myristicin, safrole, and elemicin overdose. This updated review paper intends to attract more attention to nutmeg oil and its potential to be developed into a medicinal product for the prophylaxis and therapy of diseases.

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 essential oils from two members of the Asteraceae ( Acanthospermum hispidum DC. aerial parts, and leaves of Tithonia diversifolia (Hemsley) A. Gray), growing wild in Osun State, Nigeria, have been characterised by combined gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analyses. Twenty-nine components have been fully identified and grouped into monoterpene hydrocarbons (22.2%), oxygenated monoterpenes (4.6%), sesquiterpenes hydrocarbons (58.2%) and oxygenated sesquiterpenes (10.8%) in A. hispidum. The main constituents of the oil were β-caryophyllene (28.0%), α-pinene (15.9%) and bicyclogermacrene (11.0%) among the hydrocarbon compounds, and bisabolol (8.9%) and carvacrol methyl ether (4.1%) among the oxygenated components. Tithonia diversifolia essential oil comprised seventeen components and was characterised by a predominant content of monoterpene hydrocarbons (87.9%), cis-β-ocimene (43.7%), α-pinene (28.6%) and limonene (12.0%) being the main compounds. Sesquiterpenes represented ca. 10% oil, as sum of hydrocarbons and oxygenated components. A new chemotype is established for T. diversifolia, while the Nigerian A. hispidum is being reported for the first time as a new source of essential oil with some distinction in composition from those of other sources.

ABSTRACT: The Annonaceae family consists of ~135 genera with diverse species and a large number of chemical compounds arising from the secondary metabolism. However, the chemical composition of the essential oil of several species of the family such as Cardiopetalum calophyllum has not been completely determined. In this study, the essential oils extracted from the leaves, flowers, and fruits of C. calophyllum , collected in typical areas of the Cerrado of Goiás, were characterized. The essential oil was extracted by hydrodistillation for 4h using a Clevenger apparatus. The chemical analysis was carried out by gas chromatography-mass spectrometry (GC-MS), and the constituents were identified by comparing the spectra and retention index obtained with those available in the literature. Twenty three compounds were identified in the essential oil of leaves; the oxygenated sesquiterpene, spathulenol (28.78%), was the major compound. Twenty five compounds were identified in the flowers, mainly comprising sesquiterpene hydrocarbons, germacrene-D (37.03%) and germacrene-B (13.72%). Seventeen compounds were reported in fruits, mainly comprising sesquiterpene hydrocarbons, germacrene-D (28.19%) and germacrene-B (20.90%), and an oxygenated sesquiterpene, spathulenol (11.53%). This is the first report on the chemical composition of the essential oils from leaves, flowers, and fruits of C. calophyllum.

Numerous articles on Salvia officinalis L. have been published regarding the composition of their essential oil. The considerable variation found may be due to the quality of the plant material as well as to the methods used for analysis. A simple GC-MS method was developed and optimized in the QbD approach, for the determination of sage essential oils. The optimization of GC-MS analysis was performed using different mobile phase flows, injection volumes, split ratios and temperature programs. The optimized method proved to be simple and can be successfully applied for the determination of sage essential oils.
