The quantitative determination of some phenolic acids in Delphinium formosum by HPLC
(Marcel Dekker Inc, 1999)Some phenolic acids from the flowers of Delphinium formosum have been determined quantitatively by reversed-phase high-performance liquid chromatography with diode-array detection. A comparative study was performed by ... -
Recent studies on the alkaloids of anatolian Thalictrum species
(2001)Studies which have been conducted in the last 25 years on the alkaloids of 9 Thalictrum taxa out of 11 growing in Turkey are reviewed. 58 alkaloids including 12 new alkaloids have been isolated and characterized by ... -
Selective preconcentration of thorium in the presence Of UO22+, Ce3+ and La3+ using Th(IV)-imprinted polymer
(Elsevier Science BV, 2005)We have prepared Th(IV) ion-imprinted polymers, which can be used for the selective preconcentration of Th(W) ions, represented by uranium and lanthanides. N-methaeryloyl-(L)-glutamic acid (MAGA) was chosen as the complexing ... -
Selective separation of thorium using ion imprinted chitosan-phthalate particles via solid phase extraction
(Taylor & Francis Inc, 2006)We have studied a new method for the preparation of Th(IV)-imprinted chitosan-phthalate particles, which can considerably enhance the adsorption capacity and selectivity of thorium ions. In this study, chitosan-phthalate ... -
Simultaneous depletion of albumin and immunoglobulin G by using twin affinity magnetic nanotraps
(Taylor & Francis Inc, 2016)For biomarker discovery, simultaneous removal of albumin and immunoglobulin G (IgG) become more important for both concentrating other species including potential biomarkers and getting rid of their masking effect. In this ... -
