The hydro-distilled essential oil of Citrus reticulata Blanco var. kinnow was analyzed by Gas chromatography-mass spectrometry (GC-MS). Five constituents out of fifteen constituents were identified from seeded C. reticulata oil representing 74.66% of the oil. The major constituent of the oil was ?- phellandrene (62.00%). ?-pinene(6.53%), ?-myrcene(2.81%), limonene(2.81%) and caryophyllene(0.51%) were present in considerable amount. From the low seeded C. reticulata oil, six components out of seventeen compounds were identified constituting 54.74% of the oil and the main component was ?-phellandrene (37.35%). ?-pinene(2.79%), ?-pinene(3.26%), ?-myrcene(4.16%), limonene(5.77%), caryophyllene(1.41%) were present in considerable amount.

The essential oil from the twig of Litsea mollis was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by gas chromatography–mass spectrometry (GC-MS). A total of 39 compounds were identified, representing 89.27% of the oil. Among the twig oil compounds, oxygenated monoterpenes (39.06%) and sesquiterpene hydrocarbons (36.62%) were predominant (75.68% in total). Among the oxygenated monoterpenes, eucalyptol (9.9%), (R)-citronellol (7.23%), (R)-citronellal (7.0%), and (Z)-citral (5.03%) were the major compounds. Of the sesquiterpene hydrocarbons, β-caryophyllene (7.96%), (-)-α-panasinsene (6.31) and à-Caryophyllene (6.28%) were the main components.

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.

Satureja Montana

The aim of the studies was to determine the optimal term of harvest for Satureja montana L. (winter savory) in order to obtain the essential oil rich in antioxidative compounds such as carvacrol, p-cymene, γ-terpinene and β-caryophyllene. Essential oils of S. montanaaerial parts were obtained by hydrodistillation in Deryng-type apparatus and analyzed by gas chromatography/mass spectrometry (GC/MS). In total, 30 compounds were identified in the savory volatile oil under different harvesting terms (before flowering, during flowering and after the flowering), that represented 94.61 to 97.55% of the oils. The major components were carvacrol (65.43 to 69.99%), its precursors: p-cymene (3.69 to 9.69%) and γ-terpinene (1.51 to 5.92%) as well as β-caryophyllene (2.74 to 4.71%). Moreover, the term of harvest had a significant effect on the content of main essential oil constituents. The highest concentrations of carvacrol, γ-terpinene and β-caryophyllene were observed in the herb collected before flowering, while the highest amounts of p-cymene were noted after the flowering.
