Chemotaxonomic study of 25 taxa(24 species and 1 variety) of Eurya

in a total of 28 samples were carried with high performance liquid chromatograms method. Twenty-three chemical components from the whole samples were recognized according to the relative retention time of the chromatograms. The results showed that the chromatograms stabilized between same species and varied among different species

which could be used to distinguish species from each other. In order to reveal the inter-specific relationships and the taxonomic positions of these species

chromatograms data were submitted to cluster analysis using UPGMA and NJ methods and then the taxonomic significance of chemical component in genus Eurya were discussed based on the two dendrograms. Our study showed that the HPLC chromatograms method was rapid

intuitive and repeatable

and it could be mentioned as a good marker to classify the plants of Eurya. In addition

this study also provided useful data for studying the resource utilization in the genus.
