Iljin and Serratula coronata L. Due to dry mineralization and calculations of molar extinction coefficient it was possible to determine percentage of inorganic contaminants content and their types in solid form. Extraction and identification of anthocyanins is a long lasting process, which requires optimization of many factors.

J Med Plants Res 3 The attempt of receiving high purity anthocyanins in solid form was shown. The most optimal was chosen: Anthocyanins are extracted using solvent like methanol, ethanol or acetone, acidified with HCl to prevent these compounds from degradation.

The basic structure of anthocyanins is flavylium ion, to which saccharide residues are often added. It was found that type of compound, solvent and time of extraction have influence on efficiency of anthocyanins isolation process.

The determination of the exact composition and comcentration of metabolites in the plant tissues is an important chromayografia of cognitive. Colour of solid anthocyanins was black with shade of violet and absorption spectrum indicates that anthocyanins did not decompose during the process so this method seems to be efficient.
