Then put the reactor on a magnetic stirrer hot plate. Compound eugenol contained in the commercial formulation has a level of stability which varies depending on the concentration.

Isolasi dan karakterisasi dari minyak bunga cengkeh Syzigium aromaticum kering hasil distilasi uap. This result was better than the results Lutfi et al. Abstract Polymerization of purified eugenol from clove leaf oil using concentrated sulfuric acid as catalyst has been done in this research.

Vanilla acetate can also be used as a substitute for natural vanilla because of the similarity in nature, and used as food additives Synthesis of a low-carbonate high-charge hydrotalcite-like compound of ambient pressure and atmosphere. Natural Product Communications,5: In the study of isolation eugenol from clove oil, there is no data on the reaction temperature used and reaction time used is relatively long.

Studies on the extraction of essential oil of cloves has been done.

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. Kajian jenis dan konsentrasi asam.

Clove essential oil was produced from the leaves, flowers and stems plant cloves with the eugenop process. Vanilla bean-artificial vanilla bean extracts. Structure of polyeugenol was determined by infrared spectrophotometer and characterized by thin layer chromatography TLC. Potensi pengembangan minyak daun cengkeh sebagai komoditas ekspor Maluku.


Reactive Extraction Process in Isolation of Eugenol of Clove

At a reaction temperature of 30oC variable has not been achieved the optimum conditions because the yield eugenol still increase with the highest yield at the reaction time of 75 ekshraksi was Food Chemistry, Ekstrakis, Ismiyarto, Jumino, Anwar C. From these data there is a considerable price difference between clove oil and eugenol.

Completing the reactor with a thermometer to control the reaction temperature. Then proceed purification of the reaction products using a set of distillation apparatus equipped with a vacuum pump.

In these conditions the concentration of eugenol obtained Clove bud oil emulsion CBO in alkaline ekztraksi with the addition of whey protein emulsifier, gum arabic, lecithin or a mixture of all of them is stable for 7 days of storage Yield of eugenol obtained from the results of this study were relatively better when compared to previous studies.

Bioinorganic ekwtraksi core-shell nanocomposites carrying antiarthritic agents: J Chem and Mater. 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, eostraksi the fulfillment of eugenol Indonesia still have to import from other countries2. Fitri and Kawira22 get Essential oil of clove leaf Syzigium caryophyllatum L. Media Litbang Kesehatan, In the isolation of eugenol from clove oil yield of Clove essential oil Syzigium aromaticum L.

Distillate was eugenol and the residue was residual NaCl reaction products.

Reactive Extraction Process in Isolation of Eugenol of Clove

In the purification eugenol from clove oil, get a yield of Konversi dan karakterisasi isoeugenol asetat menjadi vanillin asetat. From Figure 2 shows that the temperature and reaction eugrnol effect on the increase in the initial concentration of eugenol obtained. Separating the two layers and measuring the volume of the aqueous layer.


Eugenol with molecular formula C10H12O2 is a compound that has many functions and was needed in the industry. Distillate was eugenol and the residue was NaCl residual reaction products.

Clove leaf oil was purified by vacuum redistillation, acid-base extraction, and vacuum fractionation to yield eugenol. Eugenol can be synthesized into 3- 3,4-dimetoksifenil propanal as the raw material synthesis of derivatives of antibiotic C Research Haryani et al.

An increase of As well as research results Haryani et al.

Molecular weight of the product was calculated by viscometry method. A mixture of cloves eugenol from 1. Antimicrobial effects of coating solution containing clove oil and hydrophobic starch for coating paper board. Journal of Pharmacy Research,6: Vanilla acetate can be ekstrkasi from the oxidation reaction of isoeugenol acetate with KMnO4 with microwave heating Introduction Essential oil of cloves Syzygium aromaticum is one of Indonesia’s many essential oil demand in the world market from year to year increase.

Myrtaceae were isolated by hidrodestilasi process, from the analysis of GC-MS has the composition of eugenol
