Abstract. FTIR spectroscopy is used to develop a rapid and effective analysis method for studying integrally the main constituents in the medicinal plants of Humboldtia brunonis, Kingiodendron pinnatum, Derris scandens, Caesalpinia mimosoides. The chemical constituents in the leaves of these plants were identified and monitored for the qualities of medicinal properties. FTIR was applied and IR spectrum in mid infrared region 4000–400 cm–1 was used for discriminating and identify various functional groups present in the medicinal plants. The findings indicated the presence of high concentration of lignin and polysaccharides in these medicinal plants. The studies have shown clearly the differences of categories of chemical constituents among the taxa investigated.
Key words: FTIR, biomolecules, functional groups, chemical constituents, rare, endangered medicinal plant.
