Tagetes Erecta L

Steam distillation oil (SDO) and simultaneous distillation oil (SDEO) were obtained from Tagetes Erecta L. leaf of Heilongjiang province by steam distillation method and simultaneous distillation method, respectively. The yields were 0.0943% and 1.005%. Compared the differentiation of essential oil through the GC-MS analysis, the result indicated that there were twenty-nine kinds of compounds can be confirmed from SDO and fifty-one kinds can be confirmed from SDEO. The two kinds of essential oil were assayed for affinity to scavenge sodium nitrite for the purpose of characterizing mechanisms of nitrite cleaning activity. Both show strong nitrite cleaning activity up to a concentration of 0.1mL.The maximum scavenging rate was 95.18% (SDO) and 54.28% (SDEO).

Orange Peels

Kisar sweet orange is an endemic fruit and primary commodity from Kisar Island, Southwest Maluku Regency - Maluku Province. Currently, Kisar sweet orangeswere only consumed as fresh fruit during this time, partially processed into juice and the peels were discarded as wastes. Kisar sweet orange peels can be processed into essential oil to increase their economic value. The essential oil made from orange peels is highly preferable, especially for the middle to upper-class consumers, for health and air-freshening purposes.  This essential oil has a higher selling value. This research aims at isolating and identifying the chemical components and quality of essential oil made from Kisar sweet orange peels. This essential oil was isolated using a steam distillation method, and its chemical components were identified using GC-MS instruments.. The research results showed that the essential oil made from Kisar sweet orange peels dried with a cabinet dryer for two days utilizing the steam distillation method provides a yield of 0.53%, with its properties of specific gravity of 0.8457, refractive index of 1.4651 (20°C), acid number of 1.92, ester number of 8.05, and solubility in alcohol of 1:9. The main chemical component of the essential oil made from Kisar sweet orange peels detected by GC-MS is limonene (70.80%).

Essential Oil Yield

In present study, a steam distillation method has been adopted for extraction of the essential oil from Vietnamese lemon (Citrus aurantifolia) peel harvested from Tien Giang Province, Vietnam. Various extraction conditions influencing the oil yield were investigated. The resulting essential oil was evaluated for physico-chemical characteristics and antibacterial activities. The chemic al composition of oil was investigated by GC-MS. The results showed that with grinded lemon peel, a ratio of water and lemon peels of 3:1 (mL/g), extraction time of 90 min at 120 ºC, the highest essential oil yield was attained at 2.1 %. Bioactive components found at high content included limonene (64.90 %), γ-terpinene (13.70 %), β-pinene (11.89 %), α-pinene (2.11 %), β-cymene (1.80 %) and sabinen (1.52 %). The lemon essential oil in this study was found to inhibit five bacteria strains including Staphylococcus aureus, Bacillus cereus, Escherichia coli, Salmonella enterica and Pseudomonas aeruginosa.

Anti Inflammatory

Essential oil extracted from Melaleucagenus has been widely used worldwidefor many purposes. Most of the its has been reported as the source of phytochemical compound where mostly have anti-inflammatory, antiulcer, antioxidant, antimicrobial and insecticide properties. Thus, three objectives that have been highlighted in this study are (1) to extract essential oil (cajuput oil) from fresh leaves of MelaleucacajuputiPowell using simple steam distillation,(2) to determine the chemical components of MelaleucacajuputPowell essential oil using GCMS and (3) to compare the chemical compound and its percentage with the previous study.Results found that there were 41 chemical compounds that have been identified. The chemical compounds were monoterpenes such as α-terpinolene, α-pinene, sabinene, 4-terpineol and γ-terpinene. The highest chemical compounds found were caryophyllene (20.16%), α-terpinolene (17.0%),α-humulene (11.91%), βelemene (7.62%) and γ-terpinene (5.62%). In previous research, 1,8-cineole chemical compound was foundhowever, in this study a different chemical compound found, it was caryophyllene, this is due to different geographic area.As a conclusion, most of the compounds found was aromatic, antibacterial andinsecticide properties.

The steam distillation method was used to obtain samples of essential oil of some species of genus Agastache L. introduced in Belarus. More than 20 components have been identified and determined in the essential oils of Agastache pallidiflora ssp.neomexicana L., Agastache aurantiaca L., Agastache mexicana L., Agastache foeniculum L. by gas liquid chromatography.The quantitative composition of the samples of essential oils depends on the type of plant material. The main its components are limonene, 1.8-cineol, mentone, isomentone, methyl chavicol, methyeugenol. The main component of essential oils Agastache pallidiflora ssp. neomexicana L. и Agastache aurantiaca L is mentone (40–65 %). Essential oil Agastache foeniculum L. is enriched with pulegone and isomentone. Methyl chavicol and methyleugenol dominate in Agastache mexicana essential oil. Distribution of the enantiomers of limonene, menthone and pulegone are shown. Regardless of the plant species, the samples are optically pure in the (+)-pulegone. The nature of the distribution of the enantiomers of limonene and menthone is an individual characteristic of the studied Agastache L. essential oils.

Essential oil was obtained in a yield 1.1%, w/w, by steam distillation of Elionurus tristis leaves from Madagascar. The chemical composition was analyzed qualitatively and quantitatively by GC-MS and GC-FID, respectively. To the best of our knowledge, this is the first chemical analysis of this essential oil. Seventy-three compounds were identified, corresponding to 94.9% of the total essential oil. The principal compounds were sesquiterpenes and the more represented were β-gurjunene (18.4%), neoclovene (15.8%) and nootkatone (10.4%). Through a comparative study, we observed a large variability between the components of E. tristis essential oil and those from others species of the same genus. Evaluation of the antioxidant (ABTS and DPPH assays) and anti-tuberculosis activities of the essential oil showed weak antioxidant potency but an interesting anti-tuberculosis activity with a MIC of 32 mg/L. This activity prompted us to evaluate individually the major components for the treatment of tuberculosis.

The aim of this research was to examine the larvicidal activity of essential oil (EO) extracted from nutmeg (Myristica fragrans Houtt) leaves and fruits by steam distillation, and to analyze its chemical compounds. The EO yield of nutmeg leaves and fruits collected from the same tree was 0.66% and 0.30%, respectively. Larvicidal tests with the EO were carried out against Aedes aegypti (L.) (Diptera: Culicidae). The concentrations of nutmeg EO used for the larvicidal assay were 50, 100, 150, 200, and 250 μg/mL. The results showed that fruit oil was more toxic than the leaf oil. LC50 values of leaf and fruit EOs were 133.8 and 110.1 µg/mL, respectively. The chromatogram of GC-MS showed that the chemical components in nutmeg leaf and fruit EOs were dominated by α-pinene, sabinene, β-pinene, delta-3-carene, limonene, β-phellandrene, α-terpinolene, linalool, safrole, croweacin, and myristicin.
