摘要

印度尼西亚是世界上广藿香油生产国之一,但问题是广藿香油的质量,特别是广藿香醇含量仍然低于规定的标准。提高广藿香醇含量的方法之一是分馏法。本研究旨在了解广藿香醇初始浓度和柱高对广藿香油中广藿香醇含量增量的影响。采用完全随机设计(CRD),试验设计包括两个因素,第一因素为广藿香醇初始浓度(C1 = 31、11%,C2 = 32、83%,C3 = 33、61%),第二因素为柱高(H1 = 25 cm, H2 = 45 cm)。方差分析表明,维格鲁柱的高度对广藿香醇含量的增加有实际影响。当广藿香醇初始浓度为31.11%,柱高为45 cm时,蒸馏残渣中广藿香醇的含量最高(83,86%)。广藿香油渣馏分中广藿香醇含量越高,其比重和折射率越高,在乙醇中的溶解度越好。结果表明,该样品的比重为1.013,在乙醇中1:5澄清,折射率为1.5166。

Effect of the Fractional Distillation on an Increment Patchouli Alcohol Content in Patchouli Oil
: Indonesia is one of the patchouli oil producers in the world, however, the problem is the quality of patchouli oil, especially patchouli alcohol content that are still below the required standard. One of the methods that can be used to increase the content of patchouli alcohol is fractional distillation method. This research aims to know the influence of the initial concentration of patchouli alcohol and height of column against increment of patchouli alcohol content in patchouli oil. The experimental design which used was Complete Randomized Design (CRD) consist of two factors, first factor namely the initial concentration of patchouli alcohol (C1 = 31,11%, C2 = 32,83%, and C3 = 33,61%) and second factor is height of column (H1 = 25 cm and H2 = 45 cm). Analysis of variance shows that the height of vigreux column has a real influence against the increased levels of patchouli alcohol. The highest levels of patchouli alcohol (83,86%) obtained from the residue fraction of distillation with 31.11 % initial concentration of patchouli alcohol and 45 cm height of column. The higher levels of patchouli alcohol in patchouli oil residue fraction, the higher specific gravity and the refractive index, and solubility in ethanol will be easier. The result shows that this sample have 1.013 specific gravity, clear in ethanol at 1:5 and have 1.5166 refractive index.
