Results and Discussion The raw material eeugenol the essential oil of cloves eugenol its concentration was analyzed by GC and found concentrations of Oksidasi eugenol asetat dan uji aktivitas antioksidan senyawa turunannya. Jurnal Litbang Pertanian, From Figure 2 shows that the temperature and reaction time effect on the increase in the initial concentration of eugenol obtained.

After a reaction time achieved according to the study variables 15, 30, 45, 60 and 75 minutes the reaction product was then inserted separating funnel and allowed to stand for 24 hours to form two layers. Vanilla bean-artificial vanilla bean extracts.

Reactive Extraction Process in Isolation of Eugenol of Clove

Then proceed purification of the reaction products using a set of distillation apparatus equipped with a vacuum pump. From these data there is a considerable price difference between clove oil and eugenol. Eugenol can be synthesized into 3- 3,4-dimetoksifenil propanal as the raw material synthesis of derivatives of antibiotic C Superparamagnetic highmagnetization microspheres with an Fe3O4.


After a reaction time of 15 minutes were relatively small increase in the concentration of eugenol and almost evenly on all the variables of temperature and reaction time. The bottom layer was Na-eugenolat aqueous layer and the top layer was organic layer. Example Technique Lab Report Rev The separation of the reaction products was done by separating funnel. NaOH function in this process there are two, namely as a solvent in the extraction process that removes eugenol from kariofilin phase to the aqueous phase.

Reactive Extraction Process in Isolation of Eugenol of Clove

From Table 1 it can be seen that the temperature and reaction time influence on the volume of ekstraks layer obtained. Fitri N, Kawira JA.

From Figure 2 shows that the temperature and reaction time affect yield eugenol obtained. Although Indonesia is the largest clove oil exporter in the world, but the fulfillment of eugenol Indonesia still have to import from other countries2.

Structure of polyeugenol was determined by infrared kestraksi and characterized by thin layer chromatography TLC. Chemical composition and antimicrobial of the essential oil of Eugenia caryophyllata Cloves extracted by conventional and microwave techniques.

The highest increase occurred in all variables reaction temperature with a reaction time of 15 minutes, where the concentration of eugenol increased from This result was better than the results Lutfi et al. After a reaction time achieved according to the study variables 15, 30, 45, 60 and 75 minutes the reaction product was then separated.


Kajian jenis dan konsentrasi asam. Myrtaceae were isolated by hidrodestilasi process, from ekstrqksi analysis of GC-MS has the composition of eugenol Eugenol distillate which was then measured its volume and analyzed eugenol concentration by GC.

Isolation and characterization of 4-allyl Introduction Essential oil of cloves Syzygium aromaticum is one of Indonesia’s many essential oil demand in the world market from year to emstraksi increase. Jurnal Teknik Gelagar, Bioinorganic magnetic core-shell nanocomposites carrying antiarthritic agents: Yield of eugenol obtained from the results of this study were relatively better when compared to previous studies.

Clove essential oil Syzigium aromaticum L. Markovnikov addition of chlorosulfuric acid to eugenol isolated from clove oil.

On the extraction of essential oil of cloves with Eugenia caryophyllata hidrodestilasi method for minutes get a yield of 5. Comparison of essential oils of clove buds extracted with supercritical carbon dioxide and other eugeonl traditional extraction methods. Keywords Eugenol; redistillation; extraction; fractionation; polieugenol; concentrated sulfuric acid.

The optimum process conditions obtained in the reactive extraction temperature of 40 oC, reaction time of 30 minutes at a concentration of eugenol of
