ResumoThe nonsaponifiable fraction of flowers and stems of the terrestrial orchid Arundina and leaves and stems of mixed Cattleya species were examined for nonsaponifiable constituents. Common to both, in the organs examined, were campesterol, stigmasterol, and β-sitosterol. In Arundina these sterols occurred largely as the mixed glycosides. A more detailed study of Cattleya, mainly the leaves, indicated a series of saturated long chain alcohols as the major constituents, and cycloeucalenol, cycloartenol, and 24-methylene cycloartanol as minor triterpenoid constituents.
