Standardization of Eucalyptus globulus leaves and Cetraria islandica slan

Keywords: 1,8-cineole, chlorophylls, polysaccharides, phytochemical screening


The aim. The aim of this study was to propose methods of standardization of Eucalyptus globulus leaves and Cetraria islandica slan by the main group of biologically active substances (BAS). This was done for further development of complex medicines based on Eucalyptus globulus leaves and Cetraria islandica slan.

These studies provide an opportunity for further development and standardization of extracts from these plants, and the main aim of this study is the development and standardization of a complex medicine.

Materials and methods. Thin layer chromatography was used to determine the presence of these markers. Quantitative values of these biologically active substances were determined by spectrophotometric method according to the relevant methods of the State Pharmacopoeia of Ukraine.

Results. Markers for the certification of Cetraria islandica and Eucalyptus globulus have been proposed in this study. Chlorophylls and 1,8-cineole were chosen as a marker for the study of Eucalyptus globulus, and polysaccharides were chosen as a marker for Cetraria islandica. The qualitative and quantitative content of these markers in the studied objects was studied.

Further research in this direction will be aimed at developing methods for control and standardization of water and alcohol extracts from these plants.

Conclusions. Biologically active substances in medicinal plant raw materials were studied. It is proposed to study extracts and finished products from Eucalyptus globulus leaves and Cetraria islandica slan using these methods.

The method of qualitative and quantitative determination of polysaccharides in Cetraria islandica slan is easy to apply and easily reproducible. It is important to be able to standardize Eucalyptus globulus leaves for essential oils and chlorophylls.

The biologically active substances-markers found in Eucalyptus globulus leaves and Cetraria islandica slan will be used for the development of herbal medicines, the standardization of which will be carried out for the same compounds.
