THE STUDY OF ELEMENT COMPOSITION OF PEAR LEAVES OF NOIABRSKA CULTIVAR
Introduction. Mineral elements are enzyme cofactors, constituents of vitamins, hormones, all body cells and tissues, they are essential for its normal metabolism: homeostasis support, progress of biochemical, enzymatic, plastic, hormonal, regulatory and metabolic processes, being a necessary and vital part of human diet. Their deficiency, excess or imbalance in the body may cause certain diseases, syndromes, disorders or pathological states.
The object of the study were pear leaves of Noiabrska cultivar, collected in Ivano-Frankivsk region in August 2018. Pears of this cultivar are widely cultivated on the territory of Ukraine in private households or farms, especially in Western and Transdniester regions.
The aim of the study – research on the qualitative composition and quantitative content of mineral elements in pear leaves of Noiabrska cultivar.
Research Methods. The element composition of pear leaves of Noiabrska cultivar was studied using atomic-absorption spectrometry at the department of analytical chemistry of the State Scientific Institution “Institute for Single Crystals” of National Academy of Sciences of Ukraine.
Results and Discussion. The obtained results of experimental research carried out show the presence of 19 mineral elements in pear leaves of Noiabrska cultivar. K (2185 mg/100 g), Ca (1140 mg/100 g), Mg (380 mg/100 g), P (85 mg/100 g), Si (76 mg/100 g) and Al (62 mg/100 g) were accumulated in the highest amount in the plant material, while Cu (0.23 mg/100 g), Ni (0.11 mg/100 g) and Mo (0.047 mg/100 g) – in the lowest. The content of heavy metals was within the limits of permissible concentration.
Conclusions. 19 mineral elements were identified in pear leaves of Noiabrska cultivar, and their content was determined by the means of atomic-absorption spectrometry. The received experimental data will be used in further work at predictive modeling of pharmacological activity of the plant material studied, medicinal agents on its basis, as well as at standardization and development of quality control methods for the plant material.
