Fourier-transform infrared (FTIR) spectroscopy is increasingly applied as a rapid and non-destructive method for the characterization of biological materials. The aim of this study was to evaluate the applicability of FTIR spectroscopy combined with chemometric analysis for assessing biochemical diversity in leaves of selected ornamental plant species. The study included representative houseplants with different morphological and physiological traits, such as succulent and non-succulent species. Leaf samples were collected under controlled conditions, subjected to standardized preparation, and analysed using attenuated total reflectance FTIR spectroscopy over a wide spectral range. The obtained spectra were pre-processed and analysed using chemometric methods, including principal component analysis (PCA), to identify patterns and relationships within the dataset. Particular attention was paid to the spectral regions associated with polysaccharides, proteins and phenolic compounds, which are key components of plant tissues. The applied approach enables the evaluation of biochemical variability between plant samples and provides insight into the potential of FTIR spectroscopy as a supportive tool for plant characterization. The study contributes to the development of rapid analytical techniques for assessing plant diversity and quality in a non-destructive manner.
