Three triterpenoid alcohols, i.e., ilexol, α- and β-amyrin have now been isolated from the unsaponifiable fraction of the ethereal extract of the bark of Ilex crenata Thunberg (Family: Aqufoliaceae). Stearic acid has also been isolated from the fatty-fraction of the hydrolysates. In view of phylogenetic and taxonomic standpoigts, the occurrence in various sorts of bird-lime of triterpenoids and β-sitosterol discussed'in this paper.
