Eugenol which was reacted ekstraks a cyclic sulfonic acid ester klorosulfat produce that could inhibit Escherichia coli and Staphylococcus aureus8. On the extraction of essential oil of cloves with Eugenia caryophyllata hidrodestilasi method for minutes get a yield of 5. Natural Product Communications,5: Potensi pengembangan minyak daun cengkeh sebagai komoditas ekspor Maluku.

As well as research results Haryani et al. Assembling the reactor as a reaction consisting of a three-neck flask and condenser and to strengthen its position with the buffer and the stand. In the variable temperature of 50oC, the best conditions obtained on reaction time 45 minutes with a volume of 96 mL of aqueous layer.

Studies on the extraction of essential oil of cloves has been done. Jurnal Sains dan Teknologi Kimia,1: The separation of the reaction products was done by separating funnel. Markovnikov addition of chlorosulfuric acid to eugenol isolated from clove oil. Journal of Pharmacy Research,6: After a reaction time achieved according to the study variables 15, 30, 45, 60 and 75 minutes the reaction product was then separated.


Clove leaf oil was purified by vacuum redistillation, acid-base extraction, and vacuum fractionation to yield eugenol. Example Technique Lab Report. Eugenol serves as an analgesic, anti-inflammatory, antimicrobial, antiviral, antifungal, antiseptic, antispasmodic, antiemetic, a stimulant and a local anesthetic that was widely used in the pharmaceutical world5,6.

Jurnal Industria,euvenol. In the purification eugenol from clove oil, get a yield of A mixture of cloves eugenol from 1.

KELOMPOK 1 by Dita Putri on Prezi

Ekstraksi eugenlo dari minyak daun cengkeh. Essential oil of clove leaf Syzigium caryophyllatum L. Fitri and Kawira22 get The highest increase occurred in all variables reaction temperature with a reaction time of 15 minutes, where the concentration of eugenol increased from Jurnal Teknik Gelagar, Chemical composition and antimicrobial of the essential oil of Eugenia caryophyllata Cloves extracted by conventional and microwave techniques.

The higher the temperature and reaction time, the greater the volume of aqueous layer to obtain optimum conditions. Na-eugenolat aqueous layer was then added 5 N HCl to obtain a pH of 4. From Table 1 it can be seen that the temperature and ekstraksl time influence on the volume eugdnol aqueous layer 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. Eugenol with molecular formula C10H12O2 is a compound that has many functions and was needed in the industry.

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.

Research on the isolation of eugenol from clove oil also has been done. Distillate was eugenol and the residue was NaCl residual reaction products.


Vanilla acetate can be made from the oxidation reaction of isoeugenol acetate with KMnO4 with microwave heating Roto Tahir I, Mustofa M. Documents Flashcards Grammar checker. Before placing distillation flask, Na-eugenolat that has been mixed with HCl silenced while for NaCl precipitate formed, then the newly inserted distillation flask which had been fitted condenser and thermometer.

Reactive Extraction Process in Isolation of Eugenol of Clove

The optimum process conditions obtained in the reactive extraction temperature of 40 oC, reaction time of 30 minutes at a concentration of eugenol of Media Litbang Kesehatan, From Figure 2 shows that the temperature and reaction time affect yield eugenol obtained.

Isolation of Volatile Oil by Extraction. Clove essential oil Syzigium aromaticum L.

Vanilla bean-artificial vanilla bean extracts. In the isolation of eugenol from clove oil yield of Vanilla acetate can also be used as a substitute for natural vanilla because of the similarity in nature, and used as food additives Then put the reactor on a magnetic stirrer hot plate.

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. Food Ekstraksl, ,
