Propolis is a resinous hive product is known for its diverse biological activities, which are largely attributed to its complex phytochemical composition. The present study aims to investigate the influence of different extraction solvents on the chemical profile of stingless bee propolis, Trigona apicalis. Propolis samples was subjected to maceration using different polarity solvents such as hexane, ethyl acetate and methanol. The resulting extract were characterized via Ultraviolet (UV)-Visible and Fourier-transformed infrared (FTIR) spectroscopy. UV-Vis analysis revealed distinct chromophore patterns across the 200–500 nm range. The aromatic chemicals are represented by peaks at range 260–280 nm whereas flavonoids and phenolic structures are identified by peaks at the region 300–380 nm. Additionally, FTIR spectroscopy demonstrated a comprehensive fingerprint of functional groups including O-H stretching, C=C aromatic stretching and C=O stretching vibrations. These spectroscopic data highlight significant compositional variations in polyphenols, flavonoids, and lipids based on the solvent used, reflecting the importance of solvent selection in optimizing the extraction of bioactive constituents.
