Phenylpropanoids and polysaccharides from Plantago depressa and P. media growing in Buryatia

Abstract

The composition of phenylpropanoids and polysaccharides from leaves of Plantago depressa and P. media (Plantaginaceae) growing in Buryatia was studied. Caffeic and chlorogenic acids and acteoside were found in the studied plants; isoacteoside and plantamajoside, in P. media. The dominant compound in P. depressa was acteoside (8.72 mg/g); in P. media, plantamajoside (7.69 mg/g). These were responsible for the pronounced antiradical activity. Polysaccharide components that were extracted by water and an oxalate mixture were highly esterified pectinic substances with anti-atherogenic activity.
