Abstract
The need for essential oils is increasing along with the increasing development of
modern industries such as the perfume, cosmetic, pharmaceutical, food, aromatherapy
and drug industries (Ella et al, 2013). Citronella is processed and processed to obtain
pure essential oil so that it gets a high selling value, and research is carried out to
identify GC-MS using 100 grams of citronella extract with the extraction process using
500 ml of methol solvent and evaporated for 25 minutes at 60°C. The results of GC-MS
got the components from the highest to the lowest, namely the highest compound was
hydroxymethyl of 33.40% with a retention of 6,500 minutes, the second highest
compound was nonadecane of 29.47% with a retention of 23,559 minutes, the third
highest compound was dodecanoic of 14.51 with a retention of 22.863 minutes, the
fourth compound was pyran. of 13.31 with a retention of 5.333 minutes, and the lowest
compound is dodecanoic of 9.31 with a retention of 23,333 minutes. From the results of
the identification test of citronella extract using methanol as a solvent, the highest
compound component is the hydroxymethyl group, this compound has several functions,
namely, as an antioxidant and anti-microbial.
