Chirality – Isolation of Limonene from Citrus Fruits Introduction: Terpenes are a large and varied class of hydrocarbons produced by a wide variety of plants. Many essential oils belong to the terpene class. They are made up of two or more five carbon units that are called isoprenes. Limonene is a terpene that can be separated from orange peels almost 100% in the (R)-(+)-limonene form. Other citrus fruits like lemons‚ grapefruits‚ limes‚ and tangerines contain the compound as well. The

Oil Extraction The oil from citrus fruits is loaded with limonene. Extract the oil from the citrus rinds and use it to make insecticides whenever needed. A couple of small drops of citrus oil is all that is required to make insecticide spray. Sprinkling diluted oil around gardens repels pests. Keep the oil on hand and mix insecticides whenever a problem arises. To extract the oil‚ dry and grind the peels and leave them to soak in grain alcohol. Strain the mixture and leave the alcohol to evaporate

Liquid CO2 Extraction of D-Limonene This convenient‚ effective and inexpensive liquid CO2-based extraction of a natural product (D-limonene) provides an engaging example of natural products extraction using an alternative solvent (liquefied CO2). Because the procedure can be carried out in a polypropylene centrifuge tube and uses crushed dry ice as its CO2 source‚ it provides an inexpensive alternative to the equipment-intensive extraction with supercritical CO2.

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
