1.1. 4,8,12-Trimethyltridecanoic acid has been isolated and identified from a sample of sheep perinephric fat which earlier yielded phytanic and pristanic acids. This acid had formerly been isolated in the pure state from marine fish oil1 and whale oil2.2.2. The present finding, supported by det...

A two-dimensional non-comprehensive high-performance liquid chromatographic (HPLC) system coupled to electrospray ionization tandem mass spectrometry was developed for the determination of skin allergenic hydroperoxides of limonene and linalool. These compounds are some major components behind s...

Linalool is a major volatile component of tea aroma. It occurs naturally as R-(−)- and S-(+)-linalool enantiomers, which exhibit entirely different sensorial properties. Using headspace solid-phase microextraction with chiral gas chromatography, we quantitated R-(−)- and S-(+)-linalool in teas. ...

Linalool is a major constituent of the essential oil of several plant species and possesses several biological activities. In this work, we studied the effects of linalool on excitability of central neurons of land snail Caucasotachea atrolabiata and tried to elucidate the underlying mechanisms....

Cinnamomum osmophloeum ct. linalool (土肉桂 tǔ ròu guì) is one chemotype of the indigenous cinnamons in Taiwan. This study examined the anxiolytic potency of leaf essential oil (LEO) from C. osmophloeum ct. linalool and its main constituent on 4-week ICR mice using an open field test (OFT), a...

The most commonly used drugs against visceral leishmaniasis are based on pentavalent antimonial compounds, which have played a fundamental role in therapy for over 70 years. However, the treatment is painful and has severe toxic side effects that can be fatal. Antimonial resistance is spreading ...

Famous oolong tea (Oriental Beauty), which is manufactured by tea leaves (Camellia sinensis) infected with tea green leafhoppers, contains characteristic volatile monoterpenes derived from linalool. This study aimed to determine the formation mechanism of linalool in tea exposed to tea green lea...

Jasminum species are among the most preferred fresh cut flowers in India since ancient times. The plant produces small and fragrant flowers, which are of great demand in the preparation of fragrant garlands and also in perfume industries. Floral volatile of Jasminum grandiflorum L. (Family: Olea...

Linalool (I) was extracted from Zingiber officinale. The oxidation of linalool using m-chloroperbenzoic acid at room temperature gave the mixture of 2,2,6-trimethyl-6-vinyl-tetrahydro-pyran-3-ol (IIa) & 2-(5-methyl-5-vinyl- tetrahydro-furan-2-yl)-propan-2-ol (IIa′), which cannot be separated. W...

Cinnamomum osmophloeum (土肉桂 tǔ ròu guì) ct. linalool is one of the chemotypes of the indigenous cinnamon in Taiwan. S-(+)-linalool is the major constituent of leaf essential oil (LEO) of C. osmophloeum ct. linalool. This study aimed to investigate its physiological effects including body w...

Several new compounds containing both chloro and dimethylamino groups linked to silicon have been prepared. The general method involved reacting a solution of the appropriate polychlorosilane in ether at ca. - 50° with a chilled ethereal solution of dimethylamine. Prepared in this fashion were ...

Seven novel binuclear Pt(II) metalated complexes based on substituted 3,6-diphenylpyridazines have been synthesized and structurally characterized using XRD crystallography, NMR spectroscopy and HR ESI mass-spectrometry. Three of these complexes contain two {Pt(CˆN)} metalated fragments located ...

The design of environmentally benign methods for preserving wood in service requires an understanding of the precise sequence of the biochemical events that occur as wood is colonized. We hypothesize that in-situ precipitation of existing calcium ions in association with pectin in wood may preve...

The hydroxamic acids R·CO·(NH·OH) have been investigated, in which R is H; CH3; CH2C1; CH3(CH2)10; CH3(CH2)14 and C6H5, respectively. Included in this work are some O- and N-derivatives of hydroxamic acids, and of methyl benzimidate. The spectra of the hydroxamic compounds are interpreted by ...

A new cyclic diaza-dihydroxamic acid, 1,4-diazacycloheptane-N, N′-bis(N-methyl-acetohydroxamic acid) (DACHDMAHA) has been synthesized and studied. This paper is the second one devoted to finding synthetic ferric sequestering agents suitable for mimicking chemical and biological properties of th...

A thermodynamic cycle to calculate pKa values (Minus log of acid dissociation constants) of hydroxamic acids is presented. Hydroxamic acids exist mainly as amide isomers in the aqueous medium. The amide form of hydroxamic acids has two deprotonation sites and may yield either an N-ion or an O-io...

Separation process facilitated by selective adsorption of chemical reagents can be modulated through an in-depth understanding of reagent-surface interaction, which is of both fundamental and practical importance in a wide range of industrial applications. Hydroxamate is a class of widely used r...

The reaction between medium and long chain fatty acyl thioesters and neutral hydroxylamine results in the formation of acyl hydroxamic acids. Separation and identification of acyl hydroxamates is facilitated by conversion of these compounds to their acetyl derivatives. Thin-layer chromatoplate a...

Hydroxamic acids (HA), with the general formula R–CO–NHOH, are chelating agents which may be used in a number of interesting applications, such as medicine and waste water treatment. In this paper, we describe the enzymatic synthesis of HA with various chain lengths (from C2 to C18), using thr...

The extraordinary ultrafast tunable saturable absorption properties of metal complexes M(PAAL)2 (M = Co, Ni, Cu, Zn) containing redox-active 1-(2-pyridylazo)-2-acenaphthequinol ligands (PAAL) were investigated by Z-scan and pump-probe system. The obtained third-order nonlinear optical (NLO) abso...
