of Acetyleugenol (Clove Oil) from Cloves Purpose In this experiment‚ you will obtain the essential oil from cloves by steam distillation. You will then separate a component (acetyleugenol) from the oil by liquid-liquid extraction. Finally‚ you will isolate the acetyleugenol by using a rotovap for reduced pressure distillation‚ which will remove the organic solvent (dichloromethane). Background Whole cloves contain between 14% and 20% by weight of essential oils‚ but only half

when dried‚ provide the cloves of commerce. The flowers have a strong refreshing odour if the seed are allowed to mature‚ most of the pungency is lost. Each berry has only one seed. The trees fruit usually about eight or nine years after planting. The whole tree is highly aromatic. The finest cloves come from Mallacca and Pemba and also East & West Indies‚ Mauritius and Brazil. Ethenomedicinal Practice It is used as a domestic spice world-wide. Tincture of cloves has been used for skin infections

Isolation of Eugenol from Cloves Abstract The experiment conducted‚ isolation of eugenol from cloves‚ is the extraction of the essential oil. To perform this experiment cloves and water were mixed together and heated by a heating mantle in a round-bottom flask. A direct stem distillation took place‚ and the oil product was out aside for a week. After one week‚ the isolation of the eugenol actually takes place. Next the thin-layer chromatographic analysis takes place‚ but the experiment

Cross* Summary The isolation of Eugenol from Cloves begins with whole cloves and then using a steam distillation apparatus to obtain the cloves oil substance. Then with the mixtures of water and dichloromethane to form two immiscible layers. The layers were dichloromethane substance and aqueous The entire substances that are separated into two individual

Isolation of the Major Constituents of Clove Oil Organic Chemistry Laboratory II‚ 10 February 2011 Corey Cates Introduction and Objectives The purpose of this lab was to obtain a pure sample of clove oil from ground cloves using steam distillation‚ perform infrared spectroscopy on the sample‚ and analyze the IR to identify the major constituent in the clove oil. The first day the clove oil was removed from the ground cloves into an aqueous solution then removed from the water using DCM. The sample

and isolate a natural product from cloves. Introduction By performing steam distillation we can isolate eugenol at lower temperature than its usual boiling point of 248 degree Celsius. Eugenol belongs to a category called essential oil. Many of these compounds are used as flavoring and perfumes and in the past were considered the essence of plant from which they were derived. Structure of eugenol (clove oil) and eugenol acetate: Reagents: Eugenol‚ CH2Cl2‚ Br2‚ FeCl3‚ Methanol

principle component of oil of cloves is an aromatic compound‚ which is identified by thin layer chromatography (TLC). Eugenol is widely used in dentistry‚ due to its analgesic‚ antiseptic balsamic qualities. It is ideal for curative for pulp hyperemia (the soft‚ sensitive substance underneath the enamel and dentine of a tooth) and pulp its. In dentistry eugenol is also used to cover cavities‚ fill canals‚ etc. It also keeps food fresh and kills off bacteria and viruses. Eugenol helps keep meat fresh

Distillation – Clove Oil Abstract: In this experiment‚ a situ method steam distillation was performed and essential oils were isolated from cloves. Once the oils were obtained‚ extraction techniques were used to extract a crude‚ eugenol‚ and acetyleugenol product sample. These samples were submitted for GC analysis and the normalization area percents were calculated to confirm their purity; for the crude sample it was 93.95% eugenol and 6.05% acetyleugenol‚ for the eugenol sample it was 100%
