Steam distillation of eugenol composition

Launch: This research involves a great extraction of the natural product using the tactics of steam distillation. The principle component of oil of cloves is usually an fragrant compound, which can be identified by thin layer chromatography (TLC).

Eugenol can be widely used in dentistry, because of analgesic, antibacterial balsamic attributes. It is perfect for curative pertaining to pulp hyperemia (the smooth, sensitive element underneath the teeth enamel and dentine of a tooth) and pulp its. In dentistry eugenol is also utilized to cover cavities, fill canals, etc .

It also keeps meals fresh and kills away bacteria and viruses. Eugenol helps keep various meats fresh and prevents belly upset, diarrhea, and wound infections. Additionally , it might play a role in reducing indigestion, controlling diarrhea, and healing reductions and attacks.

Eugenol is the main active ingredient in cloves.


1 . Within a 250 mL round bottom flask, place 10. 0g of floor cloves and 80 cubic centimeters of normal water. Set up for a simple distillation

2 . Heat to hot and acquire the distillate until you no longer see droplets of organic and natural liquid taken from the condenser (about forty five minutes).

a few. Place the distillate in a separatory funnel and extract with three 12 mL servings of Dichloromethane

4. Combine the dichloromethane extracts and dry over Sodium Sulfate.

5. Examine the chastity of the remove using thin-layer chromatography (TLC). Spot a tiny sample from the extract by using a capillary spotter about you cm through the end of TLC plate.

6. Visualize using a UV mild and mark the visualized spots with a pencil.

7. Record the quantity of spots plus the Rf principles from the spot(s).

8. Even though the plate is definitely developing set up a spending dry work set up and distil away most of the dichloromethane solvent.

on the lookout for. The remaining option of Eugenol in Dichloromethane can be removed using a disposable pipette and placed into a clean pre-weighted vial.

10. The vial could be heated on the steam bath under the hood to take out the small amount of dichloromethane.

11. The pure Eugenol should be measured to determine the percent oil reclaimed based on the mass of cloves originally used.


Density of Eugenol: 1 . 34 g/mL

BP of Eugenol: 40C

Initial mass of Eugenol: 18. 545 g

Mass of vial: 18. 0063 g

Mass of Eugenol Oil: 18. 434 g

% Restoration

= (18. 545 g ” 18. 434 g)/18. 434 x 100 = 0. 602%

Thin part chromatography:

Rf=(Distance substance moved/Distance solvent moved)

Rf=(4. 2/5. 1)

Rf=(. 824)

Bottom line:

The research was successful in that we did isolate eugenol as proven simply by thin layer chromatography. The Rf worth was to some extent high. This is probably because the beaker with the chloroform was not 95 % closed during the time we all did the thin coating chromatography. Each of our watch goblet was not fully efficient. Likewise when we were heating the liquid inside the condenser, heat the the liquid at a rate too high could cause excess materials to come out in the final product.

Other than that, human problem is a matter. This can be reduced by cautious observation, and proper method. Still, the percent problem was under 1 percent, which is very good.
