THE STUDY OF LIPOPHILIC SUBSTANCES OF TARAXACUM OFFICINALE WIGG HERB
In our paper, we provide some results of the research of photosynthetic pigments of Taraxacum officinale herb which grows in Altai region. The yield of lipophilic fraction was determined in different vegetation phases of the studied raw-material. By the TLC and spectrophotometry the following compounds were identified: β-carotene, lutein, violaxanthin, neoxanthin, taraxanthin, chlorophyll a and chlorophyll b. For the TLC analysis, the mobile phase of acetone-petroleum ether (3:7) proved to be the most efficient. The TLC method proposed in the paper can be used for inclusion dandelion (Taraxacum officinale) into the modern normative documents on medicinal raw material. The conditions of spectrophotometric method of pigments determination in Taraxacum officinale herb were experimentally chosen. The total amount of carotenoids and total amount of chlorophyll were determined for different vegetation phases of Taraxacum officinale herb. For using as a carotenoids source the most optimal vegetation phase for collection of raw material is the budding phase. The studied medicinal plant may find future application in clinical treatment of various diseases.
