The purpose of this study was to obtained optimum conditions a reactive extraction process in isolation eugenol from clove essential oil associated with the temperature and time process. Clove bud oil emulsion CBO in alkaline solution with the addition of whey protein emulsifier, gum arabic, lecithin or a mixture of all of them is stable for 7 days of storage Fitri N, Kawira JA.

From Minyal 2 shows that the temperature and reaction time effect on the increase in the initial concentration of eugenol obtained. Studies on the extraction of essential oil of cloves has been done. Minyak atsiri merupakan jenis minyak yang disuling dari berbagai macam tumbuhan seperti serai, akar wangi, cengkeh, kayu manis, nilam, mawar dan lain-lain.

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.

KELOMPOK 1 by Dita Putri on Prezi

Alston from Bangladesh were isolated by hidrodestilasi process, from the analysis of GC-MS has the composition of eugenol Konversi dan karakterisasi isoeugenol asetat menjadi vanillin asetat. Teknik Kimia5 2— And then separate them. Then put the reactor on a magnetic stirrer hot plate.

The parameter of quality corrugated sheet is bursting strength. Run the distilation process with fixed temperature and vacuum pressure 6x kPa. Comparison of essential oils of clove buds extracted with supercritical carbon dioxide and other three traditional extraction methods. Keywords DPPH Pb II acrylic acid adsorption antioxidant biodiesel carboxymethyl chitosan catalyst chitosan endophytic fungi eugenol extraction immobilization kinetics magnetite molecular docking silica synthesis temperature transesterification zeolite.


In these fari the concentration of eugenol obtained Distillate was eugenol and the ekstrakssi was NaCl residual reaction products. The reaction between eugenol and NaOH was a fast reaction reaches equilibrium. Sono-assisted preparation of magnetic magnesium—aluminum layered double hydroxides and their application for removing fluoride. Structure of polyeugenol was determined by infrared spectrophotometer and characterized by thin layer chromatography TLC.

Example Technique Lab Report. Research on the isolation of eugenol from clove oil also has been done. Commonly, methyl halides and dimethyl sulphate are used as methylation agent. Medicinal value of clove.


Majapahit 62 Mataram Indonesia. Methylation was shown by the formation of a light yellow liquid Although Indonesia is the largest clove oil exporter in the world, but the fulfillment of eugenol Indonesia still have to import from other countries2.

Keywords Eugenol; wugenol extraction; fractionation; polieugenol; concentrated sulfuric acid.

Controlling the temperature of the reaction was done by looking at the temperature of the thermometer mounted on the reactor. Potensi pengembangan minyak daun cengkeh sebagai komoditas ekspor Maluku. Food Chemistry, Kimia Student Journal,1: Pemurnian eugenol dari minyak daun cengkeh dengan reaktan asam monoprotik.

The variable 40oC, the best conditions obtained in a reaction time of cengieh minutes with a volume of 97 mL of aqueous layer and this results in an optimum condition. User Username Password Remember me.


After a reaction time achieved according to the study variables 15, 30, 45, 60 and 75 minutes the reaction product was then separated. Na-eugenolat aqueous layer was then added 5 N HCl to obtain a pH of 4. Ekstraksu the reactor with a thermometer to control the reaction temperature. Peningkatan kadar eugenol pada minyak atsiri cengkeh dengan metode saponifikasi — distilasi vakum. Artificial fertilization will be useful ekstraksi minyak cengkeh produce larvae Tri Sulistyowati Sarah H.


Jurnal Industria,3. Research stage begins by inserting a ml clove essential oil and 0. Eugenol is the main component in the essential oil 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 Eugenol with a concentration of Antioxidant and antimicrobial activities ddaun clove bud essential oil and eugenol nanoparticles in alcohol — free microemulsion.

Reactive Extraction Process in Isolation of Eugenol of Clove

A mixture of cloves eugenol from 1. Synthesis of a low-carbonate high-charge hydrotalcite-like compound of ambient pressure and atmosphere. In this research dimethyl carbonate, an alternative methylation agent is used, because of its low toxicity, green, and economic.

Compound eugenol contained in the commercial formulation has a level of stability which varies depending on the concentration. From Table 1 it can be seen that the temperature and reaction time influence on the volume of aqueous layer obtained. NaOH function in this process there are two, namely as a solvent in the eygenol process that removes eugenol from kariofilin phase to the aqueous phase.

ekstrakso 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. Sintesis 3- 3,4-dimetoksifenil -propanal sebagai senyawa antara dalam pembuatan turunan antibiotik C dari minyak daun cengkeh. Research Haryani et al. Eugenol which was reacted with a cyclic sulfonic acid ester klorosulfat produce that could inhibit Escherichia coli and Staphylococcus aureus8.
