Hydrophobic Isoprenoids from Stems of Astragalus galegiformis from the Flora of Georgia

Previously, we reported the isolation of flavonoids and cycloartanes from the aerial parts of Astragalus galegiformis L. (Leguminosae L.) [1, 2, 3]. Leaves and flowers of the plant contained flavonoids as oligosides of kaempferol, quercetin, and isorhamnetin [1]. Stems were dominated by cycloartanes, i.e., cyclogalegigenin derivatives (0.35–0.5% yield of raw material mass), that exhibited cardiotonic and hypocholesterolemic activity [4].

In continuation of research on isoprenoids from this plant, we studied compounds extracted by CHCl3 from the aqueous alcohol extract. Air-dried ground stems (0.326 kg) that were collected during full bloom in the vicinity of Tbilisi (Georgia) were exhaustively extracted with EtOH (75%). The EtOH was evaporated. The residue was extracted with CHCl3 (4 × 200 mL). The CHCl3was evaporated. The residue (120 g) was dissolved in a small amount of MeOH and reprecipitated by hot water. The mixture was cooled and filtered. The filtrate was condensed to a dry...
