Localities and seasonal variations in the chemical composition of essential oils of Satureja montana L. and S. cuneifolia Ten

The essential oils of Satureja montana L. and Satureja cuneifolia Ten. were subjected to detailed GC-MS analysis in order to determine possible similarities between them and also the differences in their chemical compositions, depending on the locality and the stage of development. The plant materials were collected prior to, during and after flowering from three different locations in the central part of Dalmatia (Croatia). For both plants the qualitative composition of the components appeared to be constant in three phenological stages and in three different localities. However, considerable differences were found to exist in the amounts of several compounds. Copyright (C) 2001 John Wiley & Sons, Ltd.
