Evaluation of Tanacetum larvatum for an anti-inflammatory activity and for the protection against indomethacin-induced ulcerogenesis in rats
(Elsevier Ireland Ltd, Clare, 2003)
Oral administration of the chloroform extract from Tanacetum larvatum (Griseb. ex Pant.) Kanitz caused a dose-dependent anti-inflammatory effect in the carrageenan-induced rat paw oedema test. The obtained anti-inflammatory ...
Photochemical degradation of solid-state nisoldipine monitored by HPLC
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
The photochemical degradation of solid-state nisoldipine, 1,4-dihydropyridine calcium antagonist, was investigated under daylight and UV light conditions. Degradation products were identified by using the retention times ...
Trace elements analysis of Echinacea purpurea - herbal medicinal
(Elsevier Science BV, Amsterdam, 2003)
Elemental composition of Echinacea purpurea (Asteracae), grown in Serbia under strongly controlled conditions, has been studied. To distinguish elemental patterns of different parts of the plant, the content of Zn, Fe, Cu, ...
Determination of all pK(a) values of some di- and tri-carboxylic unsaturated and epoxy acids and their polylinear correlation with the carboxylic group atomic charges
(Scientific Reviews Ltd., 2003)
For a series of seven unsaturated and seven epoxy di- and tricarboxylic acids, pK(a)(a) values were determined potentiometrically in aqueous media at 25 degreesC and an ionic strength of 0.1 M (NaCl). The thermodynamic ...
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 ...
