rudbeckia hirta/polysaccharide

From the leaves of Plantago lanceolata, the green parts of Rudbeckia fulgida, the aerial parts of Salvia officinalis and the roots of Valeriana officinalis, crude polysaccharides have been isolated by extraction with water and further purified and fractionated by various techniques. The

An alkali-extracted low-molecular glucuronoxylan and two water-extractable polysaccharide complexes isolated from various parts of Rudbeckia fulgida were tested for antitussive activity on mechanically induced cough in nonanaesthetized cats. Glucuronoxylan consisted of a (1-->4)-linked

Eleven polysaccharides have been isolated from the leaves of Arctium lappa var. herkules, Aloe barbadensis, Althaea officinalis var. robusta, Plantago lanceolata var. libor, aerial parts and roots of Rudbeckia fulgida var. sullivantii, stems of Mahonia aquifolium, and peach-tree (Prunus persica) gum
