Abstract

Annotation. The total anthocyanins content, total carotenoid content and total content of chlorophylls a and b in leaves of fruit and berry crops common to the Western Kazakhstan region were analyzed using UV-vis spectrophotometry. Twelve plant species were studied in this work. Anthocyanins level in leaves varied from 0.041 to 0.532 mg/g, carotenoid levels were from 0.56 to 3.87 μg/g dry weight. The range of chlorophylls a and b content is significantly wider (2.15 to 14.07 and 1.8 to 9.1 µg/g respectively). Among the investigated plants R.canina has the highest levels of natural pigments. It has been observed that P.armeniaca is the plant richest in anthocyanins, in turn R.canina and A.ovalis was found to be richest in carotenoids. It was also found that the pigments content depends on plant species and the content of chlorophyll a exceeds the content of chlorophyll b from 1.19 to 2.75 times.
