Experiment: The Isolation of R (+)- Limonene from Orange peel I. Abstract: In this experiment, steam distillation method was used to extract limonene from orange peel. sample; the optical rotation will then allow us to calculate the enantiomeric excess of Percent Weight or R-Limonene in Peel = (Mass of R-Limonene/Mass of Peel)*100, Volume of Test Tube = 10.2 cm = 1.02 dm = 23.97 mL, 1. No serious or life-threatening side effects were observed on the haematological and biochemical parameters of mice fed with specific dose of EO of Citrus limettioides, therefore the EO can be recommended as safe fumigant for preservation of food commodities. The EO was also examined for any possible toxicity or adverse effect resulting from its consumption. To explain this procedure, certain terms should be introduced. The major components were dl-limonene (89.089%), -myrcene (2.933%), ()-linalool (2.927%), -pinene (0.865%), (E)-citral (0.749%) etc. Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01, 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.
