Abstract

A component of gondopuro oil is methyl salicylate. Methyl salicylate has functional groups that allow it to be reformed. Changes in functional groups can occur through chemical reactions, one of which is through the aminolysis reaction to produce salicylamide or salicylanilide. The precursor for the synthesis of amide derivatives is a carboxylic acid, using natural methyl salicylate from gondopuro oil and amines sonochemically using sonichemical methods for 3, 4, and 5 hours with temperature control of ± 60ºC. Then liquid extraction was carried out using of hexane and distilled water 2 to 3 times until 2 phases were formed, then left for 1 night at a temperature of less than 100C and decanted. Then extracted with 10 mL of cold 5% NaOH 2 times until two phases were formed, namely the n-hexane fraction and the NaOH fraction. The NaOH fraction obtained is then heated using a water bath to evaporate the solvent so that it becomes a solid, which is then placed in an oven to form crystals. The crystals obtained were then dried using an oven at 40ºC until dry, and then the yield of the synthesized powder was calculated. From the research results, it can be concluded that Salicylanilide compounds can be synthesized using sonochemical methods and produce the largest % yield in the 3rd sample at 5 hours at 11.23%. Salicylanilide compounds have anti-inflammatory activity at a concentration of 100.0 ppm with a % inhibition of 46.07%.

Abstract

The main contents of clove oil are phenolic compounds, namely eugenol, eugenol acetate and gallic acid, as well as flavonoids. One of the derivatives of the eugenol compound is acetyl eugenol which was developed by the esterification reaction between eugenol and acetic acid anhydride using the sonochemical method. Synthesis of acetyleugenol was sonicated for 30 minutes at a temperature of 70-80°C. The % yield of the synthesized compound is calculated and continued with testing which includes solubility, melting point, FTIR and GC-MS tests, which are then tested for antimicrobial activity. The research results show that eugenol and acetic acid anhydride compounds with a NaOH catalyst can be synthesized using ultrasonic waves and produce a % yield of 3.50%. The resulting synthesis can melt starting at a temperature of 30°C and can dissolve in ethanol, methanol, chloroform and ether but does not dissolve in distilled water. FTIR testing on the acetyl eugenol compound showed the presence of -OH phenolic groups, C=C alkenes, C=C aromatics, C-O esters, and C=O esters. Acetyleugenol at concentrations of 1.25%, 2.5%, 5%, and 10% was able to act antibacterial on Staphylococcus aureus cultures with a density of 1.0 X 108 CFU/mL.
