摘要：

Using perethylated beta-cyclodextrin as a chiral stationary phase the alcohols 2-methyl-1-butanol (1), -pentanol (2), -hexanol (3) and 2-ethyl-1-hexanol (4), the free carboxylic acids 2-methyl-butanoic (5), -pentanoic (6), -hexanoic (7) and 2-ethylhexanoic (8) as well as the esters methyl and ethyl 2-methylbutanote (9, 10) are resolved into their mirror images without derivatization. Chiral capillary gas chromatography was used to determine the enantiomeric distribution of the 2-methylbutanoates 9 and 10 in pineapples and 15 apple varieties, using extractive and dynamic headspace methods, respectively.
