As the extension of our work on arundoin and cylindrin from Imperata cylindrica Beauv. var. koenigii Durand et Schinz, hexane extracts of fifty- five species of Gramineae plants shown in Table I have been examined for the characterization of triterpenoids. From forty-six species twenty-seven triterpenoids, including two new compounds (X, XIV) and three new natural products, shown in Chart I were isolated and identified. The structural elucidation of the new compounds will be discussed. As the results wide occurrence of triterpenoids, especially triterpene methyl ether (II, IV, VI, X, XIV, XVII, XIX, XX, XXII) was confirmed. Coexistence of fern-9(11)-ene derivatives (I, II, III, IV) and arbor-(11)-ene derivatives (V, VI, VII, IX, X) in thirteen plants might be interesting from biogenetical point of view. Further discussion on chemotaxonomy of triterpenoids in the family will also be presented.
