Compositional changes of Citrus tamurana Hort. ex Tanaka (hyuganatsu) essential oil were analyzed after storage for 1, 3, 6, and 9 weeks at -21, 5, 20, and 30 degrees C. The total amount of oxides increased greatly. The contents of monoterpene alcohols and ketones also increased. The total amount of monoterpene hydrocarbons was unchanged up to 30 degrees C. However, the contents of myrcene, gam...
The emission enhancement behavior and photocleavage activity of a ruthenium(II) arene complex, [(η(6)-p-cymene)Ru(dppn)(py)](2+) (1) (dppn = 4,5,9,16-tetraaza-dibenzo[a,c]naphthacene, py = pyridine), towards DNA were compared with [(η(6)-p-cymene)Ru(bpy)(py)](2+) (2), [Ru(bpy)2(dppz)](2+) (3) and [Ru(bpy)2(dppn)](2+) (4) (bpy = 2,2'-bipyridine, dppz = dipyrido-[3,2-a:2',3'-c]phenazine). It was ...
Thyme (Thymus vulgaris L.) is an important plant of family Lamiaceae and its essential oil is famous among 10 essential oil of medicinal plant. In present study, effects of nitrogen application methods was evaluated at two moderate and semi arid zones for distinguishing the best nitrogen application method in each habitat considering the growth differentiation balance (GDB) for vegetative produ...
Thermolysis of a xylene solution of Cp2Fe2(CO)4 and PPh3 yields primarily Cp4Fe4(CO)4 (1) together with smaller amounts of (C5H4Ph)Cp3Fe4(CO)4 and Cp3Fe3(CO)3(PPh2). Cluster 1 can be alkylated and arylated by using organolithium reagents to give the derivatives (C5H4R)Cp3Fe4(CO)4. This reaction is competitive with reduction of 1 by the organolithium reagent. A more versatile method for function...
Black cumin (Nigella sativa L., Ranunculaceae) is an annual herb commonly used in the Middle East, India and nowadays gaining worldwide acceptance. Historical and traditional uses are extensively documented in ancient texts and historical documents. Black cumin seeds and oil are commonly used as a traditional tonic and remedy for many ailments as well as in confectionery and bakery. Little is k...
Lippia sidoides Cham is a typical herb species of Northeast Brazil with widespread use in folk medicine. The major constituents of the essential oil of L. sidoides (EOLs) are thymol, p-cymene, myrcene, and caryophyllene. Several studies have shown that the EOLs and its constituents have pharmacological effects, including antibacterial, anti-inflammatory, antioxidant and neuroprotective activity...
The major components of oregano and thyme essential oils that had previously been shown to inhibit Escherichia coli O157:H7 were determined by high-performance liquid chromatography with UV detection and liquid chromatographic tandem mass spectrometry. The MICs and MBCs of carvacrol, thymol, p-cymene, and gamma-terpinene against a strain of E. coli O157: H7 phage type 34 isolated from bovine fe...
Background: Thymus deanensis is a known aromatic plant which grows widely in Iran and many mediterranean regions. In previous studies composition of essential oils of many species of Thymus genus reported which they were rich of phenols like Thymol and Carvacrol. Methods: Water distilled essential oils from aerial parts of Thymus deanensis var. deanensis from three different localities in Iran...
to investigate the antifungal effects of essential oils of khuzestani savory (satureja khuzistanica jamzad), rechingeri savory (s. rechingeri jamzad), carvacrol and benomyl on botrytis cinerea, this study was carried out in a pda medium, and on grapes, kiwi fruits and strawberry. the experiment was laid out factorially based on a completely randomized design with three replications. the results...
With the aim of exploring the anticancer properties of organometallic compounds with bioactive ligands, Ru(arene) compounds of the antibacterial quinolones nalidixic acid (2) and cinoxacin (3) were synthesized, and their physicochemical properties were compared to those of chlorido(η(6)-p-cymene)(ofloxacinato-κ(2)O,O)ruthenium(II) (1). All compounds undergo a rapid ligand exchange reaction from...
