Thin-layer chromatography of several antihypertensive drugs from the group of angiotensin converting enzyme inhibitors / Tankoslojna hromatografija nekih antihipertenziva iz grupe angiotenzin konvertujućih enzim inhibitora
(Srpsko hemijsko društvo, Beograd, 2001)
A rapid and simple method for the chromatographic separation of pharmacologically active components contained in some antihypertensive drugs has been developed employing thin-layers of silica gel and polyacrylonitrile ...
Salting-out thin-layer chromatography of some angiotensin converting enzyme inhibitors on different sorbents
(Vieweg, Wiesbaden, 2001)
Chromatographic behaviour of six anti hypertensive drugs from the class of ACE inhibitors was studied under conditions of salting-out thin-layer chromatography on silica-gel, cellulose and polyacrylonitrile (PANS) as ...
Chemical composition of the essential oil of the species Artemisia eriantha Ten. (Asteraceae) from Yugoslavia
(Taylor & Francis Inc, Philadelphia, 2001)
The essential oil of Artemisia eriantha Ten. (Asteraceae) from two localities on the mountain Durmitor in Montenegro (Yugoslavia) was studied using GC/MS. The oil yield was 0.7% and the major constituents were identified ...
Variability of essential oils of Satureja montana L. and Satureja kitaibelii Wierzb. ex Heuff. from the central part of the Balkan peninsula
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
The results of the essential oil composition confirm that there are differences between populations within the same subspecies (Satureja montana ssp. montana), between the subspecies (Satureja montana ssp. montana and ...
Synthesis of new stereoisomeric nitrate esters derived from isosorbide-mononitrate II: Bicyclic delta-lactams and tetrahydrofuran derivatives
(Georg Thieme Verlag, 2001)
The synthesis of the diastereomeric nitrate esters (3R,4R)-(2-hydroxy-4-nitrooxytetrahydrofuran-3-yloxy)acetonitrile (5b) and (3R,4S)-(2-hydroxy-4-nitrooxytetrahydrofuran-3-yloxy)acetonitrile (9) was achieved by the Beckmann ...
The use of a response surface methodology on HPLC analysis of methyldopa, amiloride and hydrochlorothiazide in tablets
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
A multifactor optimisation technique is successfully applied to develop a new HPLC method in which methyldopa, hydrochlorothiazide and amiloride were analysed and determined on a C18 column with detection at 286 nm. The ...
A preliminary study of beta-cyclodextrin/metoprolol tartrate inclusion complex for potential enantiomeric separation
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
The inclusion complex formation between Metoprolol tartarata (MeT) and beta -cyclodextrin (beta -CD) has been investigated using hyperchromic shift at lambda (max) 274.4 nm of MeT. Different parameters such as stirring ...
Composition of the essential oils of seven Teucrium species from Serbia and Montenegro
(Allured Publ Corp, Carol Stream, 2001)
The essential oils of seven Teucrium species (T. arduini L., T. botrys L., T. chamaedrys L., T. flavum. L., T. montanum L., T. polium L., T. scordium L.) growing wild in Serbia and Montenegro were studied by GC and GC/MS. ...
Simultaneous HPLC determination of nitrendipine and impurities of the process of synthesis
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
A method has been developed for separation of nitrendipine and its impurities of reaction partners and side reaction products by high-performance liquid chromatographic method on a RP-ls column and detection at 238 nm. The ...
Essential oil from the leaves of Eucalyptus camaldulensis Dehn., Myrtaceae from Jerusalem
(Allured Publ Corp, Carol Stream, 2001)
The leaves of Eucalyptus camaldulensis Dehn., Myrtaceae, collected in Jerusalem, contained 0.5% of essential oil. Using GC and GC/MS, 41 components were identified. The major constituents were p-cymene (24.2%) and spathulenol ...
