Project Abstract

<p> </p><p>The experiment was designed to determine the effect of two different<br>solvent (N-hexane and petroleum ether) on chemical composition of lemongrass<br>oil. The oil was extracted from lemongrass using N-hexane and petroleum ether<br>using soxhlet extraction method. The chemical composition of essential oil<br>obtained were analyse using GC-MS machine. The result shows 4.4% of oil were<br>obtained from lemongrass using N-hexane and 4.9% were obtained using petroleum<br>ether. The composition analysed by GC-MS Machine were 16.52% of Trimethyl<br>[4-(2-methyl-4-oxo-2pentyl)] phenoxysilane, 4.15% acetamide, 6.54% hexamethyl,<br>6.58% silane and 2, 4, 6-cycloheptatrien-1-one with peak area of 8.67% in both<br>solvent. But the chemical constituent present in lemongrass is higher using<br>petroleum ether compared to that of N-hexane.This indicated that petroleum<br>ether is much better in oil extraction and analyizing chemical constituents of<br>lemongrass.</p><br> <br><p></p>
