Abstract

A mixture of triterpene methyl ethers obtained from the leaf wax of Cuban sugar cane ( Saccharum officinarum L.) has been shown to consist predominantly of arundoin (fernenol methyl ether) and sawamilletin (taraxerol methyl ether), by means of preparative GLC, mass spectrometry and direct comparison with authentic specimens. Evidence for the presence, in trace amounts, of a third component having identical gas liquid chromatographic retention times with bauerenol methyl ether, was also obtained by GLC, but it did not prove feasible to further characterize this substance. Retention times, relative to 5α-cholestane are reported for nine triterpene methyl ethers which were subjected to GLC on 0·5% Apiezon L, 1·5% SE-30, 1·5% QF-1 and 1·0% CDMS columns. The mass spectra of triterpene methyl ethers are discussed.
