| Sumario: | For the first time, the composition and content of phenolic compounds (PC) of plant leaves of an endemic rare species of the Xiphidium Bunge section of the genus Astragalus L. of Siberia – Astragalus palibinii Polozhij was studied by HPLC. 11 compounds of phenolic nature were identified in water-ethanol extracts of A. palibinii leaves: gallic, p-hydroxybenzoic, chlorogenic, caffeic, ferulic, trans-ferulic, cinnamic acids, isoquercitrin, rutin, isoramnetin-3-O-rutinoside and L-epicatechin. The composition of PC in the leaves of plants of three cenopopulations A. palibinii from Khakassia is the same, with the exception of one hydroxycinnamic acid in trace amounts. The content (mg per 100 g DW) of flavonol glycosides in the leaves of A. palibinii plants varies in the range of 0.442–0.907, the content of hydroxycinnamic and hydroxybenzoic acids in the range of 98.5–109.7 and 32.5–83.9, respectively. The quantitative profiles of all the studied groups of PC are characterized by significant variability in the content of individual components. The variability of the content of hydroxycinnamic acids, flavonoids and hydroxybenzoic acids was determined as very low, medium and increased, respectively. |
