• 英文摘要： Ten samples each of China Fir, Lunanta Fir, and Daiten-a (a form of Luanta Fir) collected fromtrees of same developmental stage and same locality were used for a comparative chemical study. Theessential oil compositions, flavonoid constituents, and peroxidase isozymes of these plant materials wereanalysed by means of gas chromatography, paper chromatography and polyacrylamide disc electrophoresisrespectively. The chemical data obtained from essential oil and flavonoid analyses were used in a numericaltaxonomic study. The result of the present study indicates that the degree of divergency of chemicalcharacters between taxa of this genus is rather small. The evolutionary divergence of the taxa within thisgenus is probably a recent event on the geological time. The treatment in which China Fir and Luanta Firare recognized as two distinct species is probably unjustifiable. Small divergence has been observed asrevealed by the comparative studies of essential oils. The taxonomic treatment in which the genus isconsisted of only a single species and without any infraspecific division is also questionable. Based on theinformation obtained from the present study, the taxonomic treatment in which Luanta Fir was treated asa variety of China Fir is more acceptable.
