摘要

This study focuses on the synthesis of menthyl ester derivatives from menthol and various amino acids such as glycine, histidine, and leucine, and their characterization via high-performance liquid chromatography, Fourier-transform infrared (FTIR) spectroscopy, carbon-13 nuclear magnetic resonance (13C-NMR) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM) analyses to determine their structural, chemical, and morphological properties. The FTIR and 13C-NMR analyses provided detailed information about the molecular structure, confirming the formation of the menthol-amino acid ester derivatives. The XRD and SEM analyses revealed distinct crystal structures and surface morphologies of the menthol and the ester derivatives. Additionally, antimicrobial activity tests were performed to evaluate their effectiveness against various microorganisms. This study highlights the potential of these compounds as promising candidates for innovative applications in antimicrobial therapies and related scientific disciplines.
