Abstract

This study was aimed to determine the optimum temperature and extraction time of citrus lemon peel (Citrus limon (Linn.) Burm.F.) oleoresins by using Response Surface Methodology (RSM). The results showed that the optimum temperature and time of extraction with ultrasonic waves to produced oleoresins were 59,28ºC and 72,57 minutes. The extraction process with optimum temperature and time produced citrus lemon peel oleoresin with yield and refractive index respectively 32,47% and 1,4923. Meanwhile, the value of the density is equal to 1,3740 g/cm3 and the chemical compound was identified by GC-MS instrument. The component that was found in the citrus lemon peel oleoresin were 1-propanone, 1,3,6 Octratriene, Propanoic Acid, 2-Furancarboxaldehyde, 4-Vinyl-2-Methoxy-Phenol, 1-Pentene, Neryl Acetate, Geranic Acetate, ?-Bergamotene, Limonene, 2-Hexenal, 2-Bornanone, 2-Decyn-1-ol, Methyl Eugenol, Cis-P-Mentha-1(7),8-dien-2-ol, 1,4 Naphthalendione, Undecanal, Octadecanoic Acid, Pentadecanoic Acid, Decanoic Acid, 11-Octadecanoic Acid,GeranylButirate, Geranyl Propionate and 1,2-Benzenedicarboxylic Acid.

Abstract

This study aims to identify the components in the ethanol extract of the lemongrass-sugar palm herbal drink using the Gas Chromatography- Mass Spectrometry (GC-MS) method. The stages of this research include the extraction process of lemongrass stalk powder using hexane solvent, palm sugar powder using ethanol solvent and lemongrass-sugar palm herbal drink powder using ethanol solvent. Lemongrass-sugar herbal drink powder is a powder with the addition of 10% lemongrass stalks. Furthermore, all of the prepared samples were extracted using the soxhletation method for 5 hours with a ratio of 1:20 (w/v). Extracts from each sample obtained were analyzed with the GC-MS instrument. The compounds identified in the samples of the lemongrass-sugar palm herbal drink powder were 7 compounds such as Methanol (CAS) Carbinol, Ethanol (CAS) Ethyl Alcohol, Pentane, 2-methyl-(CAS) 2-Methylpentane, Pentane, 3-methyl-(CAS) 3- Methylpentane, Hexane (CAS) n-Hexane, Cyclopentane, methyl-(CAS) Methylcyclopentane and Nonadecan,1,2-EPOXI-. These results are almost similar with compounds identified in the sampel of palm sugar powder, except Nonadecan,1,2-EPOXI-, which is thought it come from the lemongrass stalk powder. while in the hexane extract of lemon grass stalk powder, 22 compounds were identified that could be classified as scents component. The conclusion of this study is that palm sugar has a great influence on the components that were thought to be present in the lemongrass-palm sugar herbal drink, which can be seen from the components identified, most of which are components contained in the ethanol extract of palm sugar powder. All the compounds thought to be present in the herbal drink have similarities with the Similarity Index (SI) above 90%.
