Abstract: With the rise of renewable resources as an engineering material, vegetable oils have been investigated as a resource for chemically functional molecules. There are variety of structures in vegetable oils which consist of fatty acids and other oxygen-containing ingredients that are enough to be chemically modified to add functional groups that could be used in material development. In this study, Garcinia cambogia pericarp (rind) oil was studied from the chemical-structure and precursor-feasibility point of view. The extracted oil was analyzed in terms of chemical composition by Gas Chromatography–Mass Spectrometry (GC–MS) to determine its major constituents and chemically reactive functionalities. The oil was then treated with the in-situ peracetic acid system. The structural features of the untreated and chemically modified oils were compared using Fourier Transform Infrared (FTIR) spectroscopic analysis. GC–MS analysis showed that the composition of the material is chemically heterogeneous, with the presence of compounds related to fatty acids (3.18% relative peak area), short-chain organic acids (propanoic acid, 27.24% area), and oxygenated furan derivatives (32.63% area). The results show the raw chemical properties and epoxidation response of Garcinia cambogia oil, evidenced by the marked reduction of the alkene unsaturation band at 1631.95 cm⁻¹ and the emergence of new oxirane ring absorption bands at 908.91 cm⁻¹ and 835.08 cm⁻¹. Because physical and mechanical application performance properties were not evaluated in this study, the present findings establish qualitative spectroscopic evidence of oxirane ring introduction rather than demonstrated engineering utility. The resulting epoxy functionality represents a prospective pathway for future empirical evaluation in bio-based polymers, coatings, thermoset resins, and composite materials.
