Systematics of Thuja on Leaf Monooterpenoids

The compositions of the leaf monoterpenoids in 7 species of Thuja (Thuja orientalis, T. orientalis 'Avrea Nana', T. orientalis cv. compacts, T. occidentalis, T. occidentalis 'Boothii', T. occidentalis 'Pumila', T. occidentalis 'Tiny Tim') were analyzed by GC-MS and compared between species. These Thuja contains 30 compounds and α-pinene, camphene, sabinene, myrcene, limonene, bonyl acetate, γ-terpinene, α-terpinenyl acetatee are occurred in these all species. Compounds in these leaf extracts are remarkably different between species. The simplest monoterpenoid (11 compounds) was found in T. orientalis 'Avrea Nana' the most complex monoterpenoid was in T. occidentalis 'Pumila'(26 compounds). Based on these data, similarities are computed using presence/absence matching by PAUP (Phylogenetic Analysis Using Parsimony). It appears that four taxa are present within these Thuja plants. The minimum spanning network reveals that Thuja occidentalis and Thuja occidentalis 'Boothii' were the most similar compounds.
