title: [Novel application of FTIR in medical herb chemotaxonomy].
abstract: Typical medical plants in Araliaceae, Campanulaceae, Magnoliaceae, Lauraceae, Leguminosae, Berberidaceae, Pteridophyta, etc. were studied with FTIR for the first time, and the similarities and differences within each familiar were also pointed out. Furthermore the differences in spectra of samples from different parts or collected at different time on the same plant were also discussed. The characteristic radicals of the mainly effective components in plants were identified, and the primary peaks were deciphered. It was considered that FTIR could become a rapid, reliable, impersonal and effective method in chemotaxonomy as a supplement of morphologic plant taxonomy.
