EXPERIMENT 5 CHIRALITY- ISOLATION OF LIMONENE FROM CITRUS FRUITS Arianne Mackenzie Post Laboratory Report Lab Partners: Christopher Coutu, Christin Bass TA: Maria Ballivian Thursday 17 February, 2016 Introduction The aim of this experiment was to extract and isolate limonene, an essential oil, from an orange peel, which is an example of a citrus fruit in which limonene is commonly found in. It is also safer as it nonflammable, nontoxic, easily available and It is especially concentrated in orange peels, accounting for approximately 97% of the essential oils found in this rind. The oil coming from the seeds of the carrot, the orange root vegetable we all know and eat regularly. due to its properties and that it is a supercritical fluid. limonene, we can calculate the enantiomeric excess as follows: Two other ways we can isolate R-limonene are using a soxhlet extractor (2) and a cold press The structure of limonene, an unsaturated hydrocarbon, is shown below. Abstract The aim of the experiment was to extract (+) - limonene naturally from orange peel. In this lab, extractions, classification tests, and a distillation was performed in order to isolate two natural products, eugenol and limonene. The specific combination of extraction and post processing techniques produces larger facets of THC-A crystals that separate from the highly potent terpenes true to the freshly harvested material from which they are extracted. Pressures ranging from 80-150 bars with temperatures, ranging from 28-60oC were employed. ingest, Results Purpose : The purpose of this experiment was to extract R-Limonene from a sample of orange or grapefruit using steam distillation and use the extract to determine the optical rotation of our sample; the optical rotation will then allow us to calculate the enantiomeric excess of R-Limonene in our distillate, as compared to a racemic mixture of R-Limonene and L-Limonene.
