SYNTHESIS 5-METHYL-2-(BENZOYLOXY)BENZOIC ACID AND
ANALGESIC ACTIVITY TEST IN MICE (Mus musculus)
Selinda Anggia Devi
5-Methyl-2-(benzoyloxy)benzoic acid is a salicylic acid derivative
compound that have been synthesized by reacting of 5-methylsalicylic acid
with benzoyl chloride by Schotten-Baumann method using tetrahydrofuran
as solvent and pyridine as catalyst. Synthesis results was then recrystallized
using methanol : water (1:1). The product yield 38% in the form are crystal
solid needle-shaped and white, soluble in ethanol and acetone, but insoluble
in cold water. Compound purity is evidence by melting point and Thin
Layer Chromatography (TLC). Identification of the compounds structure
were analyzed by ultraviolet spectrophotometer, infrared spectrophotometer
(IR) and proton nuclear magnetic resonance spectrometer (1H-NMR). The
result of structural analysis indicate that the compound is 5-methyl-2-
(benzoyloxy)benzoic acid. Analgesic activity test was performed in mice
use writhing test method to determine the amount of stretching in mice.
Doses of the test compounds and reference compounds (acetosal) used were
25 mg/kgBW, 50 mg/kgBW, and 100 mg/kgBW and pain inducer use 0.6%
acetic acid solution. ED50 acetosal compound is 80.35 mg/kgBW, while the
ED50 5-methyl-2-(benzoyloxy)benzoic acid is 52.36 mg/kgBW. It can be
concluded that the 5-methyl-2-(benzoyloxy)benzoic acid active as an
analgesic and have a greater analgesic activity than acetosal.
