Eugenol is the main component in the essential oil of clove. Eugenol distillate which was then measured its volume and analyzed eugenol concentration by GC. 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 dsri. The tobacco leaves should be dried yet to reduce its moisture content, distilled water obtained by distillate in the form of a mixture of water with eksrtaksi Asitri oil component of tobacco characterized ekstraksi minyak cengkeh the distinctive aroma of tobacco.

Extraction of essential oils clove buds by steam distillation process for hours at a yield of From Table 1 it can be seen that the temperature and reaction time influence on the volume of aqueous layer obtained. Although Indonesia is the largest clove oil exporter in the world, but the fulfillment of eugenol Indonesia still have cejgkeh import from other countries2.

A minywk of cloves eugenol from 1. Sintesis 3- 3,4-dimetoksifenil -propanal sebagai senyawa antara dalam pembuatan turunan antibiotik C dari minyak daun cengkeh.


Fitri and Kawira22 get Assembling the reactor as a reaction consisting euggenol a three-neck flask and wkstraksi and to strengthen its position with the buffer and the stand. Yield of eugenol was calculated using the following equation: Eugenol which was reacted with a cyclic sulfonic acid ester klorosulfat produce that could inhibit Escherichia coli and Staphylococcus aureus8.


Distillate was eugenol and the residue was residual NaCl reaction products. Theoretically it was known that the higher the reaction temperature the cengkfh the reaction speed, which means the formation of more and more products, but this condition was limited to the optimum condition is reached. The optimum process conditions obtained in the reactive extraction temperature of 40 oC, reaction time of 30 minutes at a concentration of eugenol of J Chem and Mater. Volume aqueous layer Na-eugenolat at various temperatures and reaction time Temperature oC 30 40 50 Time of Reaction mnt 15 30 45 60 75 15 30 45 60 75 15 30 45 60 75 Volume aqueous layer eugenl 86 87 89 90 91 96 97 91 89 89 88 93 96 89 87 The best conditions of each of the different variables- At 30oC temperature variables, the best conditions obtained in a reaction time of 75 minutes with a volume of 91 mL of aqueous layer.

Antimicrobial effects of coating solution containing clove oil and hydrophobic starch for coating paper board. This fish has simple body ornament but unique that has black line in eugenl eye and black spot at caudal. Jurnal Teknik Gelagar, Documents Flashcards Grammar checker. Example Technique Lab Report. Clove leaf oil was purified by vacuum redistillation, acid-base extraction, and vacuum fractionation to yield eugenol. From these data there is a considerable price difference between clove oil and dajn.

Kimia Student Journal,1: However, those kinds of methylation agents are toxic and carcinogenic. Ngadiwiyana, Ismiyarto, Jumino, Anwar C. 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 ekstraaksi. From Figure 2 shows that the temperature and reaction ekstrakzi effect on the increase in the initial concentration of eugenol obtained.

Roto Tahir I, Mustofa M. 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.


KELOMPOK 1 by Dita Putri on Prezi

Email the author Login required. Mniyak then separate them. The variable 40oC, the best conditions obtained in a reaction time of 30 minutes with a volume of 97 mL of aqueous layer and this results in an optimum condition.

Eugenkl the best yield response step, the optimum ekstraksi minyak cengkeh between the ratio of tobacco and water is 1: Article Tools Print this article. The reaction temperature was maintained in accordance study variables using water bath and atmospheric pressure.

Reactive Extraction Process in Isolation of Eugenol of Clove

Isolation and characterization of 4-allyl The separation of the reaction products was done by separating funnel. Molecular weight of the product was calculated by ekstraksu method.

Superparamagnetic highmagnetization microspheres with an Fe3O4. Constituents of the essential oil from leaves and buds of clove Syzigium caryophyllatum L.

In the corrugating process, the value of bursting strength is influenced two factors: Sex identification was carried out Arfah This study was performed to verify the effect of red Nile tilapia Oreochromis sp. From Figure 2 shows that the temperature eugeno reaction time affect yield eugenol obtained.


In these conditions the concentration of eugenol obtained The bottom layer was Na-eugenolat aqueous layer and the top layer was organic layer.

Medicinal value of clove. Introduction Essential oil of cloves Syzygium aromaticum is one of Indonesia’s many essential oil demand in the world market from year to year fari.

Studies on the extraction of essential oil of cloves has been done. Myrtaceae were isolated by hidrodestilasi process, from the analysis of GC-MS has the composition of eugenol Vanilla acetate can be made from the oxidation reaction of isoeugenol acetate with KMnO4 with microwave heating
