Identification
Biological Activities
Compounds
Erigeron canadensis contains a unique polyphenolic polysaccharide-protein complex that plays a significant role in its medicinal properties. Detailed chemical analysis reveals that the neutral carbohydrate portion of this complex is composed of several key sugars. Specifically, Erigeron contains arabinose, which makes up a substantial 24.1% of these residues. Additionally, the plant contains galactose, glucose, and xylose, contributing to the overall structural integrity of its polysaccharides. These specific carbohydrate components help form major polysaccharides like arabinogalactan, which support the plant's observed antitussive effects.
