The essential oil from leaves and stems of clove (Syzigium Aromaticum) growing in Siwa (South Sulawesi, Indonesia), was obtained by hydrodistillation and gas chromatography-mass spectrometry (GC-MS) was used to identify the constituent of the sample. There were five most compounds bioactive contained in the clove oil of the leaves and stems, namely eugenol, b-caryophyllene, 1,4,7- cycloundecatriene-1,5,9,9 tetramethyl, caryophyllene oxide, and cadinene. The eugenol compound, which is contained in the stems is 55.83% bigger than the leaves, which is 45.3%. But on the contrary, other compounds in the leaves are b-caryophyllene (25.57%), 1,4,7- cycloundecatriene-1,5,9,9 tetramethyl (8.65%), caryophyllene oxide (4.64%) and cadinene (2.31%) greater than the other compounds in the stems, namely b-caryophyllene (19.72%), 1,4,7- cycloundecatriene-1,5,9,9 tetramethyl (4.38%), caryophyllene oxide (3.48%) and cadinene (0.5%). Eugenol is the major constituent of the clove oil that can be used in pharmacology as antivirus, antimicrobial, antiseptic, and industry of perfume.

Sensitive Method

Linalool acetate, one of the major constituent of several essential oils, is heat-labile and decomposes upon exposure to the high injector temperature during gas chromatography. Here we report the development of an improved method for detection of this compound by gas chromatography mass spectrometry (GCMS) using cold on-column injection of the sample. By using this sensitive method, it has been demonstrated that a lavandin (L.x intermedia) mutant accumulates trace quantities of linalool acetate and camphor and higher amounts of cineole and borneol compared to its parent. This plant, which very likely carries a point mutation in one or more of the genes involved in essential oil production, provides a unique tool for investigating regulation of essential oil biogenesis in plants.

Optimum Extraction

Gas chromatography (GC) and gas chromatography–mass spectrometry (GC–MS) were used to compare between the essential oil components from needles of Pinus armandii Franch versus P. tabulaeformis Carr., growing on the same site at Taibai Mountain, China. Under optimum extraction and analysis conditions, 65 and 66 constituents each were identified in P. armandii and P. tabulaeformis, which accounted for 87.9% and 87.1%, respectively, of their oils. Based on their terpene compositions, we concluded that these species belong to a high-caryophyllene chemotype, with sesquiterpenes comprising 54.4% to 54.8% of the total contents. We also determined minor qualitative and major quantitative variations in some compounds. Compared with that from P. tabulaeformis, P. armandii oil had more γ-muurolene (7.5%), terpinolene (5.8%), and longifolene (5.7%). In contrast, α-pinene (8.6%) and caryophyllene oxide (7.4%) were the dominant compounds in P. tabulaeformis.

AbstractChemical composition and anticholinesterase activity of the essential oil of Pavetta graciliflora Wall. ex Ridl. (Rubiaceae) was examined for the first time. The essential oil was obtained by hydrodistillation and was fully characterized by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). A total of 20 components were identified in the essential oil, which made up 92.85% of the total oil. The essential oil is composed mainly of β-caryophyllene (42.52%), caryophyllene oxide (25.33%), β-pinene (8.67%), and α-pinene (6.52%). The essential oil showed weak inhibitory activity against acetylcholinesterase (AChE) (I%: 62.5%) and butyrylcholinesterase (BChE) (I%: 65.4%) assays. Our findings were shown to be very useful for the characterization, pharmaceutical, and therapeutic applications of the essential oil from P. graciliflora.
