Limonene is a useful product which is extracted from fruit peels which would otherwise be discarded. Bf = 195. The literature value of the optical rotation of R-Limonene was at 115.5 +/- 1.0 (1). The orange peel which is considered as a waste can be used for the extraction of limonene (D-Limonene) which has many applications ranging from food flavouring agent to cosmetics. The objective of this lab is to isolate limonene from the peel of citrus fruits and analyze the enantiomers of the compound. The depart oranges is cooked in water and therefore the oil created distilled in steam at a temperature slightly below a hundred 0 3 0 A C, well below its traditional boiling purpose. The percent yield for the D-limonene was extremely low, at 2%. The purity of limonene was found to be 19.34 % pure by the GC test.. Natural products which are chemicals extracted from It is important that the peels are finely chopped/cut/grated as small as possible the morning of lab. Optical rotations of molecules affect the specific rotation in a solution simply based on This experiment demonstrates the extraction of plant oils. 54.06g.

The essential oil of citrus peel contains limonene, a terpene family component (Isac-Garca et al., 2015). The method used in this lab to extract limonene from the orange peel was steam distillation, which is used to separate temperature sensitive compounds such as aromatic compounds. More oil is extracted from the peel.
