Abstract
Triterpene saponins of formula ##STR1## wherein R.sub.1 is H or OH and R.sub.2 is a tetrasaccharide, or alternatly pentasaccharide, chain have antiinflammatory, mucolytic and antiedemic activities. Said saponins are isolated from roots and bark of Crossopteryx febrifuga, for instance by precipitating them, in form of a complex with cholesterol or sytosterol, from an alcoholic extract of the vegetal material and by partitioning the precipitate between an apolar solvent, which subtracts the complexing agent and a polar solvent in which saponins are soluble.
