Abstract:
The genus Cinnamomum has been collected and investigated from Hubei
Province since 1982, 13 samples of essential oils were extracted by steam distillation from
fresh leaves of the various species of Cinnamomum and examined qualitatively and quantita-
tively by the method of capillary GC/MS/DS on Finnigan-4510 type. 108 compounds have
been identified, of which 30 major constituents are selected as numerical chemotaxonomical
characters, together with 17 morphological ones. The I3 samples were taken as operational
taxonomic units (OTU’s). Results obtained through R cluster analysis indicate the phenetic
distance and regular correlation among the characters, especially between morphological and
chemical ones. Results obtained through Q cluster analysis show the relationships among the
OTU’s. The Phylogenetic system of Cinnamomum in Hubei Province is also discussed in the
present paper, based on the chemical constituents and the relationship mentioned above.
