GC-MS analysis of liposoluble constituents from the stems of Cynomorium songaricum.

Abstract

In order to evaluate the differences and similarities between the liposoluble constituents in Cynomorium songaricum populations, stem liposoluble constituents in five populations of C. songaricum collected from three different geographic regions and four different hosts were obtained by solvent extraction and analyzed by GC-MS. Cluster analysis of the percentage composition of 80 compounds showed differences in chemical composition which were related to the geographic origin rather than the host. Hexadecanoic acid was the most abundant compound in the essential oils of C. songaricum from hosts Nitraria sibirica and Nitraria tanguticum. Whereas (Z)-9-octadecenoic acid was accumulated in the oils of C. songaricum from Zygophyllum xanthoxylum and Peganum harmala. Four of the five populations had characteristic components, which were specific to each population.
