Type: article
Abstract: In this work, the lake pigments aluminium, tin, iron, aluminium-calcium, tin-calcium and iron-calcium ararat kermes were obtained by means of KAl(SO4)2.12H2O (alum), SnCl2.2H2O, FeSO4.7H2O and Ca(NO3)2.4H2O solutions from Ararat kermes (Porphyrophora hameli Brand) dye insects. A reversed phase high performance liquid chromatography (HPLC) with diode-array detection (DAD) method was utilized for the identification of red anthraquinone dyes present in the lake pigments. The extraction of dyes from the lake pigments was carried out with HCl / MeOH / H2O (2:1:1; v/v/v) solution. HPLC analysis shows that carminic acid and flavokermesic acid were identified in the acid hydrolysed Ararat kermes extract (1), the non - hydrolysed Ararat kermes extract, aluminium - ararat kermes lake pigment, aluminium - calcium - ararat kermes lake pigment. CIELAB values of the lake pigments were measured.
