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

Study of Water Purification Methods Water is the most essential component of life on Earth. In the United States‚ the average person uses about 75 gallons per day of freshwater. Most of this water is pre-treated in facilities and comes out of the tap clean and ready for drinking‚ a fact many take for granted. If you are camping and hiking you won’t always have access to this source of healthy‚ potable water. Unfortunately‚ many water sources in the wilderness include microorganisms‚ bacteria

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

Isolation and Identification of Eugenol: The Fragrant Component of Cloves *Adri‚ Kiersten Jayne R.‚ Aguinaldo‚ Samuel Jr. Group 2 Department of Chemistry‚ College of Science University of Santo Tomas‚ España‚ Manila 1008 Abstract. In this experiment‚ the primary objective was to isolate eugenol from cloves. An amount of 30 grams of dried cloves and 300 mL of water was distilled over a flame for over 2 hours. The distillate underwent extraction with dichloromethane‚ water and sodium hydroxide

Clove oil contains two basic compounds: eugenol and acetyleugenol. As a result of Dalton’s Law and Raoult’s Law‚ both of these substances can be removed from the cloves with a steam distillation. Eugenol is polar due to the acidic hydroxyl (OH) group‚ but acetyleugenol is not polar. As a result‚ they can be separated by extraction from a 5% aqueous NaOH solution. Acetyleugenol will dissolve in the organic CH2Cl2 layer‚ while eugenol remains in the aqueous base layer as a phenoxide

amount of protein‚ and percent yield and an increasing trend for specific activity and fold purification. These trends come about naturally when performing multiple purification steps. To determine the success of each purification step‚ the more important factors to look at are the total activity units‚ total protein amount‚ and percent yield. Looking at our purification table (table 7) our purifications were not very successful. While our total protein followed the normal decreasing trend‚ as
