Three new alkaloids have been extracted from Kentucky 31 tall fescue seed and separated by a combination of adsorption and gas chromatography. The structures of N-formylloline, N-acetylloline, and demethyl-N-acetylloline were assigned by a combination of mass, nmr, and infrared spectroscopy. Volatile components of the purple passion fruit (Passiflora edulis Sims) were extracted from the vacuum steam distillate with ethyl ether and concentrated by distillation. The concentrate was separated into an acidic and a neutral fraction, and these fractions were separated by gas chromatography. Individual components were characterized by infrared and mass spectrometry. Microhydrolysis was also used in elucidating the structures of certain of the more complex esters. Twenty volatile compounds were identified, including 16 previously unreported in passion fruit. The majority of the compounds identified were esters, and this class included not only normal aliphatic esters but also 2-alkyl, aromatic, and unsaturated esters. Several aliphatic acids and alcohols were also identified, as was β-ionone. Contributions of these compounds to the passion fruit character are discussed.
