Ring closing metathesis/fragmentation route to (Z)-configured medium ring cycloalkenes. Total synthesis of (+/-)-periplanone C
(Amer Chemical Soc, Washington, 2006)
The combination of ring closing metathesis and beta-fragmentation offers an efficient entry into (Z)-configured medium ring cycloalkenes. The fragmentation step can be effected under anionic or radical conditions. The ...
Development and validation of liquid chromatography method for the separation of valdecoxib and its SC-77852 impurity
(Taylor & Francis Inc, Philadelphia, 2006)
A reversed-phase liquid chromatography method has been developed for the separation of valdecoxib and impurity SC-77852. The best results were achieved using a mobile phase-methanol: 1% water solution TEA (52 : 48 v/v), ...
Composition of essential oil of Artemisia campestris L. from Serbia
(Taylor & Francis Inc, Philadelphia, 2003)
The essential oil yield from the aerial parts of A. campestris was 0.2% (mL/g dried plant). The oil was analyzed using GC and GUMS and 38 compounds were identified. The principal components were sesquiterpene alcohols: ...

Polymer-stabilized emulsion systems: Structural characteristics and physical stability evaluation
(Taylor & Francis Ltd, Abingdon, 2003)
In the course of investigation of the effects of polymeric emulsifier (Simulgel(R)A) on the structural characteristics and physical stability (during storage time) of semisolid o/w emulsion systems with different emulsifier ...
Liquid chromatographic-mass spectrometric method for the determination of fluoxetine and norfluoxetine in human plasma: Application to clinical study
(Elsevier Masson SAS, 2005)
A selective, sensitive, simple, and rapid method for the simultaneous determination of fluoxetine (FL) and norfluoxetine (nor-FL) was developed and validated, and further applied to analyze plasma samples obtained from ...
Study on protolytic equilibria of lorazepam and oxazepam by UV and NMR spectroscopy
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
Protolytic equilibria in homogeneous and heterogeneous systems of lorazepam and oxazepam, which are sparingly soluble ampholytes from the class of 1,4-benzodiazepines, were studied at 25 degreesC and ionic strength of 0.1 ...
Quantitative analysis of nimesulide in plasma by thin-layer chromatography: Application to pharmacokinetic studies in man
(Research Inst Medicinal Plants, Budakalasz, 2003)
A thin-layer chromatographic (TLC) method for quantitative analysis of nimesulide in human plasma has been developed, validated, and applied to a pharmacokinetic study of healthy volunteers. A previously published method ...
