Extraction and Analysis of Lavender Oil
In this experiment, the presence of four primary molecular components of
lavender oil were identified using gas chromatography.
From the analysis of the gas
chromatographs, the chemical composition of lavender was determined.

Still, though, it was concluded that these four components—while not in
the correct percentage—were, indeed, present in the lavender oil sample.

Lavender oil is a naturally-occurring substance, found in lavender plants, that is
used in various medical treatments.
It is often used to treat wounds, prevent infection,
calm nerves, and induce sleepiness in patients.
Lavender oil is known to contain many
different components, the most abundant of which are Linalyl acetate (30-50% by
composition), Linalool 20-35% composition), 1-terpinen-4-ol, and 1,8-cineole.
It is the
purpose of this experiment to identify and confirm the existence of these components,
first by extracting lavender oil from a lavender slurry sample and then further separating
the individual molecular components of the oil and identifying them.
The method by which the lavender oil was extracted was steam distillation, which
passes steam through lavender flowers in the slurry sample, causing the oil-containing
cells of the glands to expand and break open; this releases the oil as vapor in the steam,
which is condensed in later stages of the distillation process and collected as liquid
