Determination of nabumetone in pharmaceutical formulation by flow injection analysis (FIA) with UV-detection
(Govi-Verlag GMBH, 2003)A precise and accurate FIA method for the quantification of nabumetone (NAB) in pharmaceuticals is described. The best suitable carrier solvent system consisted of ethanol: water (30: 70 v/v). Sample solution (4.7 x 10(-6) ... -
Determination of the free radical scavenging activity of Lycium extracts
(Consultants Bureau, 2003)Lycium species growing in Turkey have not so far been studied sufficiently. For this reason, non-polar and polar extracts obtained from the fruits of Lycium barbarum L. and L. ruthenicum Murray (Solanaceae) were assessed ... -
The essential oil of Achillea falcata L.
(John Wiley & Sons LTD, 2003)Water-distilled oils of Achillea falcata L. collected from two different localities in Turkey were analysed by GC-MS. Fifty-two and 60 components were identified, representing 95% and 90%, respectively, of the total oil. ... -
