Extraction of Eugenol from Cloves 02/01/2014 CHM2210L University of North Florida Abstract Eugenol is found in the essential oil of cloves and has distinct properties that make it an important product to both food and drug industries. (Bhimrao‚ et. al‚ 2004). To utilize many of eugenol’s characteristic properties‚ it is necessary to isolate this organic chemical from the other components of cloves. In this experiment‚ eugenol was isolated from a sample of cloves using a series of techniques

Introduction In this experiment‚ the essential oil eugenol (the main component of oil of cloves) will be isolated from whole cloves using the technique of simple distillation‚ which is often used to isolate liquid natural products from plants. The mixture of whole cloves and distilled water will then be heated to boiling and the distillate (a eugenol/water mixture) will be collected. The eugenol will then be separated from the water by extraction with pentane. The pentane solutions will then be

In both novels we read the story of women who left their home country and families to come to America‚ New York to be specific. Although both novels have similar story lines and characteristics; the major things that make them similar also make them different. In bay leaves

Essential oils are volatile components associated with the aromas of seeds‚ bark‚ or roots of plants. In this experiment‚ the essential oil eugenol was isolated from ground cloves using steam distillation techniques. Eugenol had a high boiling point‚ but it was isolated at a lower temperature by performing a co-distillation with water‚ a process known as steam distillation. This technique allowed the desired material to be distilled at a lower temperature than 100℃. The point of the steam distillation

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

Introduction Eugenol is a naturally occurring chemical that has medical applications such as its use as a natural dental anesthetic. It can be extracted from cloves by using the method of steam distillation. The extracted compound will then be separated from the water using methyl chloride‚ which will then be evaporated using a rotary evaporator leaving only the essential oil‚ Eugenol. IR spectroscopy will be used to determine the structure of the extracted compound. Results and Discussion Four

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 and prevents stomach upset‚ diarrhea‚ and wound
