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

oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils‚ ethereal oils or aetherolea‚ or simply as the "oil of" the plant from which they were extracted‚ such as oil of clove. Volatile oils are the odorous and volatile products of various plant and animal species. As they have a tendency to undergo evaporation on being exposed to the air even at an ambient temperature‚ they are invariably termed as volatile oils‚ essential

sources and study their properties (Clement 91). The two natural sources used in this experiment were an orange (the peel contains limonene‚ which is a terpene) and a dichloromethane solution of clove oil (which contains eugenol‚ an acetogenin). To isolate the eugenol‚ 20 mL of dichloromethane solution of clove oil was extracted twice; each time with a 15 mL portion of 3M NaOH. The aqueous extracts were then combined and acidified with approximately 17.6 mL of 6M aqueous HCl. Eugenol was isolated from

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

Manufacture of Perfume Scent from Rosa Berberifolia Background of Research Why is it that women love perfumes as much as men love cars? According to (Smith and Wade‚ 2008) “There are studies that most of women’s reason for loving perfume is because of the pheromones their bodies produce. Often these scents or perfumes trigger the increase of how much pheromone a woman’s body will produce” (p.12) In studies carried out‚ nearly 80% of all women will make a perfume purchase at least each year.

SAFFRON Saffron is a spice obtained from the stigmas of the flower of Crocus sativus Linnaeus‚ commonly known as Rose of Saffron. One of the first historic references to the use of saffron comes from Ancient Egypt ‚ where it was used by Cleopatra as an aromatic and seductive essence‚ and to make sacrifices in temples and sacred places. It was used as a remedy to sleeplessness and to reduce hangovers caused by wine. It was also used to perfume baths. Arabs used saffron in medicine for its anesthetic

compounds isolated from terpentine‚ a volatile liquid isolated from pine trees. The simpler mono and sesqui terpenes are chief constituent of the essential oils obtained from sap and tissues of certain plant and trees. The di and tri terpenoids are not steam volatile. They are obtained from plant and tree gums and resins. Tertraterpenoids form a separate group of compounds called ‘Carotenoids’ The term ‘terpene’ was originally employed to describe a mixture of isomeric hydrocarbons of the molecular formula

In the presence of water‚ liquids which are immiscible with water tend to boil below its normal boiling point. Steam distillation looks like this: Source: http://mywadud.wordpress.com Normal distillation would require extremely high temperatures and would be more time consuming. Distilling in the

Purification of Water Domestic: Distillation - In the process of distillation water is heated and evaporation takes place‚ whereby water changes back to water when cooled; this process is called condensation. The condensed water is the purest form of water‚ free from microbes‚ and impurities. Boiling - Boiling is the best and simplest method to purify water. After straining the water twice through clean muslin cloth‚ it is boiled for ten minutes lo kill the microbes present in it and also remove
