Abstract (english)

The quantitative analysis of phenolic compounds (phenolic
acids, flavonoids, total polyphenols, nontannic polyphenols and tannins) was
carried out in the samples of stems, leaves and flowers of Inula viscosa. The content
of all investigated compounds was determined using spectrophotometric
methods. The quantity of phenolic acids ranged from 1.71 to 5.92%, while the
content of flavonoids varied between 0.157 and 0.498%. The leaves contained
the highest quantity of phenolic acids. The content of total polyphenols ranged
from 4.56 to 11.30%. The quantity of polyphenols unadsorbed on hide powder
(nontannic polyphenols) was between 2.65 and 7.37% while the quantity of tannins
ranged from 1.91 to 3.93%. Statistical analysis was assessed by Student's t-
-test. The content of all investigated compounds depended on the plant organ and
climatic factors.
