Abstract
The features of the accumulation of flavonoid glycosides and hydroxybenzoic and hydroxycinnamic acids have been studied in the leaves of endemic Astragalus ionae Palibin and A. palibinii Polozhij of different ecological and geographical growing conditions of the Republic of Khakasia by HPLC method. Luteolin-7-glucoside, rutin, kaempferol-3-O-β-rutinoside, and 3 quercetin glycosides were identified from 8 glycosides of flavonoids from the leaves of A. ionae plants. Six flavonoid glycosides were found in the leaves of A. palibinii, luteolin-7-glucoside, rutin, kaempferol-3-O-β-rutinoside, and isorhamnetin-3-O-β-rutinoside were identified. No differences were found in the composition of hydroxybenzoic and hydroxycinnamic acids in plants of the studied taxa. Gallic, p-hydroxybenzoic, neochlorogenic, chlorogenic, caffeic, p-coumaric, and ferulic acids were identified in the leaves of A. ionae and A. palibinii. The differences between these species in terms of the content of phenolic compounds are most pronounced in the fact that A. ionae plants accumulate more luteolin-7-glucoside, the sum of flavonoid glycosides, and hydroxybenzoic acids. The content of phenolic compounds in plants of different coenopopulations is influenced by ecological and coenotic factors. In arid xerophytic and petrophytic communities more characteristic of these species, more caffeic acid and rutin accumulate, as well as the amount of hydroxycinnamic acids.
