Abstract：In the present article, the authors mensurated the infrared spectra of 22 conifer and broadleaf trees such as ginkgo biloba L., cycas revoluta thunb., Populus tomentosa Carr and so on using FTIR, analyzed the difference of a number of absorb peaks in fingerprint area, the characteristic absorb peak position of cellulose and lignin of these trees and their alternation regulations of relative intensity, then discussed the evolutional issue of ginkgo biloba. The results show that ginkgo biloba is different from cycas in the infrared spectra of wood but similar to the conifer trees, which illustrates the ginkgo biloba. is more evolutional than cycas in the timber’s chemical composition but with similar affiliation to conifer trees. The content of lignin in the ginkgo biloba wood is more than that in other conifer trees, which may be a original character of ginkgo biloba. Meanwhile, the ginkgo biloba has some syringyl lignins in addition to guaiacyl, and it has the evolutional tendency for broadleaf trees.
