Annotation:
In the southern region of Kyrgyzstan, the plant Prangos pabularia is
widely distributed, and has a valuable forage, medicinal, honey-bearing, soil-protective
and water-regulating value. But the chemical composition is very poorly understood.
Based on this, the roots of the Prangos pabularia plant after the growing season from the
Kara-Shoro National Park of the Uzgen district were used as the object of research. As a
result, two individual compounds were isolated and identified with previously isolated
substances from plants of other species of the umbrella families.
- Root extraction was carried out with ethanol.
- To isolate individual compounds, the following methods were used: fractionation
by polarity, column chromatography (KX) using silica gel of the KSK brand as an
adsorbent.
- Fractions were collected in 20-100 ml, the uniformity and purity of the fraction was
checked by thin-layer chromatography (TLC) on plates "SilifolUV-254" produced in
Sweden in the hexane-ethyl acetate system.
- The melting point was determined visually, the rotation angles were obtained on the
polarimeter PolamatA.
Conclusions:
1.
The coumarin composition of the roots of Prangos pobularia growing in the
South of Kyrgyzstan has been studied.
2.
As a result of studies of the chemical composition of prangos roots, 2 individual
compounds were identified: substance I and substance II.
3.
The physicochemical constants and chemical properties of the isolated substances
were determined, as a result, they were identified with previously known
compounds: substance I - karatavicin, substance II–fecalone.
