“…The work of H. Lian et al indicated that the MorinAluminum complex was satisfactorily separated on a Spherisorb 18 ODS 2, 5 mm, 150x4.6 mm column using mobile phase as methanol-water (30:70) adjusted to pH 1.0 with perchloric acid [16]. Perchloric acid was chosen due to low complexation power to Al.…”

“…In chromatographic system dissociation, hydrolysis, ion or ligand exchange can make the separation difficult. The problem is concerned with the stability of the complexes (16,17). Therefore, in this study, the stability constants of the copper (II) and aluminium(III) complexes of quercetin were determined potentiometrically by using Calvin-Bjerrum and Irwing Rossotti methods (18,19).…”

“…It was reported that the most probable stoichiometry of Al:morin is 1:2 in methanol and 1:1 in acidic media [29]. It was reported in literature to utilize the strong chelating power of flavonoids with Al 3+ to quantify flavonoids or aluminum with low detection limits based on fluorescence [30][31][32].…”

“…Recently, high-performance liquid chromatography interfaced to flame atomic spectrometry (HPLC–FAAS) [10] and a post-column derivatization procedure with 4,5-dihydroxy-1,3 benzene disulfonic acid disodium salt [11] have been used to quantify aluminium fluoride complexes in groundwater samples. Several high-performance liquid chromatography methods have been reported for the analysis of aluminium in various matrixes (aqueous, serum and wine samples), the majority of which include pre-column derivatization with lumogallion [12–14], morin [15], quercetin [16], N - o -vanillidine-2-amino-p-cresol [17] and 8-hydroxyquinoline [18, 19]. Flow and sequential injection methods have been reported for the spectrofluorimetric determination of aluminium in pharmaceutical formulations using chromotropic acid as chromogenic reagent [20].…”
