Materials (Basel). 2017 Sep 18;10(9). doi: 10.3390/ma10091094.

Crosslinked pyrrolidinium-based poly(ionic liquids) (Pyrr-PILs) were synthesized through a fast, simple, and solventless photopolymerization scheme, and tested as solid phase microextraction (SPME) sorbents. A series of Pyrr-PILs bearing three different alkyl side chain lengths with two, eight, and fourteen...

Essential oil composition of Hypericum triquetrifolium Turra growing wild in Iran.

Research in pharmaceutical sciences

Sajjadi SE, Mehregan I, Taheri M.
PMID: 26430462
Res Pharm Sci. 2015 Jan-Feb;10(1):90-4.

The chemical composition of the volatile oil from aerial parts of Hypericum triquetrifolium Turra was studied by GC-MS. Fifty components (97.1% of the total composition) were detected in the volatile oil. Germacrene-D (21.7%), β-caryophyllene (18.3%), δ-cadinene (6.4%), trans-β-farnesene (4.3%),...

Monoterpenes as nitrofurantoin resistance modulating agents: minimal structural requirements, molecular dynamics simulations, and the effect of piperitone on the emergence of nitrofurantoin resistance in Enterobacteriaceae.

Journal of molecular modeling

Shahverdi AR, Mirzaie S, Rafii F, Kakavand M, Foroumadi A.

J Mol Model. 2015 Aug;21(8):198. doi: 10.1007/s00894-015-2741-y. Epub 2015 Jul 15.

The effects of different monoterpenes and 2-cyclohexen-1-one on the antibacterial activity of nitrofurantoin against resistant Enterobacter cloacae, were compared and the minimal structural component of monoterpene required for the highest level of resistance-modulating activity was determined. Subinhibitory concentrations of...

Speciated particle-phase organic nitrates (pONs) were quantified using online chemical ionization MS during June and July of 2013 in rural Alabama as part of the Southern Oxidant and Aerosol Study. A large fraction of pONs is highly functionalized, possessing...

Computational Study of the Clustering of a Cyclohexene Autoxidation Product C6H8O7 with Itself and Sulfuric Acid.

The journal of physical chemistry. A

Elm J, Myllys N, Hyttinen N, Kurtén T.

We investigate the molecular interactions between sulfuric acid and a recently reported C6H8O7 ketodiperoxy acid formed through autoxidation from cyclohexene and ozone. Structurally similar but larger ELVOC (extremely low volatility organic compound) products formed from autoxidation of monoterpenes are...

Diurnal regulation of the floral scent emission by light and circadian rhythm in the Phalaenopsis orchids.

Botanical studies

BACKGROUND: Phalaenopsis bellina and its closely related species, P. violacea, emit linalool, geraniol and their derivatives as the predominant monoterpenes at the full-bloom stages. Geranyl diphosphate synthase (PbGDPS) is the key enzyme that converts precursors for monoterpene biosynthesis. Besides...
