PENGARUH JENIS PELARUT TERHADAP RENDEMEN MINYAK SEREH WANGI (CYMBOPOGON WINTERIANUS)

Handy Gomarjoyo

Abstract


Abstract: In Indonesia the lemongrass plant is the herbaceous plant species called
Cymbopogon winterianus. This plant is often used for flavoring food kitchen, disinfectant,
mosquito repellent and can be used as a perfume (essential oils). The essential oil has physical
characteristics, such as color, taste, odor and specific gravity. The aim of this study was to
determine yield of the essential oil of lemongrass plant by extraction method with variations of
solvent ratio (n-hexane, ethanol, and acetone). Initially the lemongrass was dried for a few
minutes. The lemongrass dried was reduced about 1/2 cm. The lemongrass 250 grams was
wrapped with filter paper and extracted for 12 hours with the ratio 1:2 (sample:solvent) using
different types of solvents (n-hexane, ethanol, and acetone) at the boiling point of each solvent.
For the purification process, separating the solvent from essential oils used simple distillation.
From the results of the study was concluded that the alcohol produces greater yields of
essential oil (31.96 %) in the liquid phase than the acetone (46.24 %) in the liquid phase and n hexane
(1.3
%)
in
the
solid
phase.
Keywords: lemongrass, aromatic lemongrass oil, extraction, sokletasi, yield
