“…Compounds for example ß-Citronellol, Elemol, α -Selinene, 4-terpinenol, 4,11-Selinadiene, Carvyol acetate (z), Citronellol, Decanal, E-Nerolidol, Farnesol, Farnesyl acetate, Globulol, Menthol and Perillaldehyde have positive correlation with elevation. This result is in accordance with Melito et al (2016). With a place at high altitude from sea level have less temperature and more average precipitation the oil components increase in their number and percent composition.…”

“…With a place at high altitude from sea level have less temperature and more average precipitation the oil components increase in their number and percent composition. Similar results were observed by Melito et al (2016). They found that altitude level and climatic condition affected the chemical composition of this species, determining the differentiation of two different chemotypes which correspond to specific environmental conditions.…”

Citrus peel is an important source of essential oil that is used in various fields such as cosmetics, perfumes, backers and medicine. The citrus peel essential oils have diversification in chemical constituents. The aim of this experiment was to observe the effect of topographical locality of orchards on composition of essential oil in citrus peel. Fruit of three citrus cultivars named as Citrus paradisi (Shamber grapefruit), Citrus reticulata (Kinnow mandarin) and Citrus sinensis (Musambi sweet orange) were collected from five different localities i.e. Rahim Yar Khan Layyah, Faisalabad, Sargodha and Abbottabad (Pakistan). The citrus peel essential oil extracted from steam distillation methods at Rosa Oil Extraction Plant and physiochemical characteristics were calculated through the course of study. A noteworthy variation in bioactive compounds availability in essential oils of citrus peel were found recorded geographical locations as well as among the cultivars. Maximum oil percentage (0.321%) was measured in Shamber from Rahim Yar Khan and minimum (0.271%) was seen in Musambi fruit collected from Abbottabad. Maximum oil density (0.834 mg cm-3) was noted in Shamber and Musambi peel essential oils that showed the similar values and minimum oil density of 0.822 mg cm-3 noted in Shamber from Abbottabad location. Limonene was the major part of citrus peel essential oils that was found in higher concentrations in all three citrus cultivars of five different localities. Layyah region observed to produce maximum peel essential oils in all citrus cultivars. All the chemical compounds except limonene showed positive correlation with the elevation while limonene showed negative correlation with elevation. Four compounds have statistically negatively correlation with maximum temperature for three citrus cultivars. In conclusion, the citrus peel essential oil has a higher amount of bioactive compounds. This composition is closely associated with the varietal and seasonal characteristics. These findings disclose that the production of essential oils of Citrus can be high value in future for satisfying local needs. As the consumption of aromatic oils is on an increasing line day by day.

“…Other studies have reported different compositions containing either neral 32Á9%, sabinene 14Á2%, linalool 9Á5%, limonene 9Á2% from Hue province (central region of Vietnam) (Son et al 2014), or a mixture of 1,8-cineole (13Á97%), c-elemene (8Á27%), caryophyllene (8Á04%), linalool (6Á94%), limonene (6Á78%) from samples collected in China . Altitude has been described as one of the most important factors affecting the composition and yield of EOs (Melito et al 2016). In our study, 1,8-cineole-rich EOs were mostly found in Ha Giang, Lao Cai and Yen Bai at a higher altitude (1000 m) than linalool-rich samples which were found at 300 m in Tam Dao, Ba Vi and Phu Tho (Table 1).…”

This study aimed to characterize the chemical diversity of Litsea cubeba leaf essential oil (EO) and its impacts on its antibacterial activity. Two major chemotypes (1,8-cineole or linalool rich) were identified in North Vietnam and both were bactericidal against several pathogenic bacteria. A distinct inhibitory effect of EO samples on Escherichia coli was observed. 1,8-cineole-rich sample (LC19) affected cell membrane, led to cell filamentation and perturbation of cell width, while the linalool-rich one (BV27) induced damages in the cell membrane and changes in the nucleoid morphology. The study demonstrates the importance of considering chemotype variations in terms of chemical composition as well as the mode of action.

“…2 Antibacterial, [3][4][5] antifungal, 6,7 anticancer, 8,9 and antioxidant [10][11][12][13] proprieties have been found in the EO extracted from its leaves. The production of secondary metabolites is affected, as in many other plants, 14 by environmental conditions; in literature are reported examples of the variability of both polar fraction 15 and volatile organic compounds. 16,17 On the basis of EO composition and the principal compounds characterizing the volatile fraction of rosemary, 3 principal chemotypes can be identified 18 : chemotype I, with a high content of 1,8-cineole; chemotype II, with a content of camphor >20%; chemotype III, with a content of verbenone >15%.…”

Rosmarinus officinalis L. is an aromatic plant belonging to the Lamiaceae family widely distributed in the Mediterranean area. The interest on this species is related to the multiple uses of the plant as a food ingredient, in the pharmaceutical and cosmetic industries. The chemical composition of essential oil (EO) from 5 accessions of R. officinalis L., collected monthly through a full year in Sardinia, has been studied by gas chromatography (GC) and GC-mass spectrometry technique. The EO ranged from 0.29% to 0.89%. The qualitative determinations revealed the presence of 27 compounds belonging to 6 chemical groups (hydrocarbon monoterpene, alcohols, aldehydes, ketones, esters, hydrocarbon sesquiterpene). Overall the GC-flame ionization detector analysis showed the presence of 7 major compounds: α-pinene (26%-28%), camphene (5%-8%), 1,8-cineole (15%-25%), borneol (5%-11%), camphor (3%-12%), verbenone (6%-15%), and bornyl acetate (4%-7%). Chromatographic data were also subjected to a chemometric approach that evidenced discrimination of the samples according to the site of collection.
