A COMPARATIVE STUDY OF SUBSTANCES-MARKERS ACETONITRILE FRACTION OF LEAVES AND FRUITS OF MALUS SYLVESTRIS
The analysis of new plant raw materials of leaves, fruits Malus sylvestris showed the content of extractive substances extracted with acetonitrile, which amounted to 4.7-5.4% for leaves and 2.3-2.8 % for fruits. The obtained extracts were used to identify substances, the presence of which is specifi c for this plant material and can be used in the future to identify raw materials in crushed and powdered form. It was found that acetonitrile extract from the fruit Malus sylvestris is characterized by the presence of 10 peaks, and for the leaves - 22 peaks, which can be considered as markers for the identifi cation of medicinal plant materials.
