Experimental studies were carried out under invitro conditions to examine the effect of Callistemon viminalis essential oil (EO) against the Echinochloa crus-galli L., Amaranthus viridis and Phalaris minor. EO composition was analysed by gas chromatography/mass spectrometry, revealing that EO was rich in monoterpenes and sesquiterpenes like eucalyptol, D-limonene, α-terpineol and caryophyllene oxide. EO applied in the concentration range of 0.5, 1, 2 and 4 μl against Amaranthus viridis, Echinochloa crus-galli L. and Phalaris minor drastically affected the germination of all test plants and inhibited root and shoot development. Not only seedling growth, even the chlorophyll content also reduced appreciably. This led to the demonstration that Callistemon viminalis EO was negatively affecting the photosynthetic process. Upregulation of antioxidant enzymes activities indicated that these enzymes were providing protection against Callistemon viminalis EO induced stress. Amaranthus viridis was reported to be more sensitive in comparison to Echinochloa crus-galli L. and Phalaris minor.

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.

The composition of the essential oils of Murraya koenigii(L.) Spreng, cultivated at six locations in Peninsula Malaysia and Borneo are presented. The oils were obtained from fresh leaves by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS); 61 compounds were identified, of which eleven were present in all the specimens analyzed. The two major volatile metabolites were identified as β-caryophyllene (16.6-26.6%) and α-humulene (15.2-26.7%) along with nine minor compounds identified as β-elemene (0.3-1.3%), aromadendrene (0.5-1.5%), β-selinene (3.8-6.5%), spathulenol (0.6-2.7%), caryophyllene oxide (0.7-3.6%), viridiflorol (1.5-5.5%), 2-naphthalenemethanol (0.7-4.8%), trivertal (0.1-1.0%) and juniper camphor (2.6-8.3%). The results suggest that β-caryophyllene and α-humulene could be used as chemotaxonomical markers for Malaysian M. koenigii, hence these specimens could be of the same stock and different from the ones in India, Thailand and China.

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.
