ABSTRACT
The experiment was
designed to determine the effect of two different
solvent (
N-hexane and petroleum ether)
on chemical composition
of
lemongrass oil. The oil was extracted from lemongrass using N-hexane and petroleum ether using soxhlet extraction method. The
chemical composition
of essential oil obtained were analyse using GC
-
MS machine. The result shows 4.4% of oil were obtained from
lemongrass using N-hexane and 4.9%
were obtained using petroleum
ether. The composition analysed
by GC
-
MS Machine were 16.
52% of

one with peak area of 8.
67%
in both solvent. But
the chemical constituent present in lemongrass is higher using
petroleum ether compar
ed to that of N-hexane.
This indicated that
petroleum ether is much better in oil extraction and analyizing
chemical constituents of lemongrass.
