Thesis 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 Trimethyl
[4-(2-methyl-4-oxo-2pentyl)] phenoxysilane, 4.15% acetamide, 6.54% hexamethyl,
6.58% silane and 2, 4, 6-cycloheptatrien-1-one with peak area of 8.67% in both
solvent. But the chemical constituent present in lemongrass is higher using
petroleum ether compared to that of N-hexane.This indicated that petroleum
ether is much better in oil extraction and analyizing chemical constituents of
lemongrass.
