Abstract:
The purpose of this study was to explore whether the concentration of limonene on orange peels is affected by either the species of the oranges or the geographical location of such oranges. Extraction of limonene from oranges sampled with the respect to a) species and b) origin was achieved via refluxing
of the well-divided orange peels in hexane and the amounts of limonene from the crude extract
determined using gas chromatographic technique (GC). This study (ongoing) will offer insights
as to how i) species or ii) geographical location or both affect the amount of limonene on the orange peels.
