ISOLASI DAN ESTERIFIKASI ASAM SINAMAT TOTAL GETAH KEMENYAN (STYRAX PARALLEONCOMUD PERK) DENGAN METIL SALISILAT MINYAK GANDAPURA

Abstract

A study was conducted with the aim of isolating cinnamyl cinnamate from styrax resin (Styrax paralleoneurum Perk) and reacting it with methyl salicylate from gandapura oil through hydrolysis and esterification. Characterization was performed using FT-IR and GC-MS. The FT-IR results indicated the success of the hydrolysis process, marked by the appearance of an O-H group at 3339.0 cm⁻¹. During the esterification stage, a shift in the carbonyl peak to 1671.0 cm⁻¹ and the appearance of aliphatic C-H absorption peaks at 2939.2 cm⁻¹ and 2850.7 cm⁻¹ originating from gandapura oil occurred, indicating that the reaction had taken place. However, GC-MS analysis showed that the target compound, cinnamyl salicylate methyl ester, had not yet fully formed, with the remaining reactants dominated by methyl salicylate and cinnamic acid. It was concluded that a reaction had occurred at m/z 131 but that it was an equilibrium reaction that had not yet reached total conversion to the target product.
