Determination Of Antioxidant Composition In Berry Juices Using Solid Phase Extraction With Copper Phthalocyanine

摘要

The paper studies selective extraction of organic fractions with antioxidant activity from plant raw materials on the new sorbent with surface layer of phthalocyanine metal complexes and further HPLC determination. The possibility of sorption concentration of the antioxidant substances amount, which include mostly vitamin B groups, on the layer of copper phthalocyanine on polymer sorbent Polysorb-2. We determined antioxidant composition of honeysuckle, huckleberry and cowberry juice, namely, gallus, gentisinic, chlorogenic, caffeic, cumaric and p-methoxybenzoic acids; epicatechin and quercetine. Detection limit of this technique is 5 mg/1 using copper phthalocyanine in the concentrator.
