The essential oils of five <i>Nepeta Species</i>. A preliminary evaluation of their use in chemotaxonomy by cluster analysis

Abstract

Abstract The essential oils of Nepeta cataria L., N. x faassenii Bergm. ex Stearn, N. nepetella L., N. sibirica L. and N. nuda L., isolated by steam distillation, were analysed by GC and GC‐MS. The compositions of the oils were submitted to a cluster analysis by application of the CLUSTAN program, with a view to testing their use in chemotaxonomy.
