Abstract

The genus Berberis (Berberidaceae) is present in Kazakhstan Flora by eight species, two of which Berberis karkaralensis Kornil. & Potapovand B. Iliensis are listed in theRedBook of Kazakhstan. But, the phytochemical studies of Kazakhstan barberry species conducted is insufficient until today. Thispaper presents the phytochemical analysis and antioxidant activity of fruit pulp of Berberis iliensis M. Pop and Berberis integerrima Bunge. Qualitative and quantitative chemical analysis revealed that the fruits of B. iliensisand B integerrima Bunge contained alkanes, alkenes, alkadienes, cyclic hydrocarbons, aldehydes,fatty alcohols, triterpenoids, ketones, silicones, free monosaccharides, fatty acids and their esters. Amides and vitamin (K1) were found in some samples. The antioxidantactivity of the fruit pulps was investigated by Trolox Equivalent Antioxidant Capacity(TEAC), CUPric Reducing Antioxidant Capacity (CUPRAC) and 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) Free Radical Scavenging Activity methods. All six barberry accessions investigated showed high antioxidant activity, especially B. iliensis.
