Statistical Analysis of Citronella Oils Species From Malaysia

Citronella oil is derived from the Cymbopogon species which are C.nardus, C.winterianus and C.martinii. The aim of this paper is to analyse the citronella oils species using boxplot analysis. The work consists of citronella oils data extraction using GC / GC-MS machine for compound identification. After that, a quick observation on the major compound in the samples as significant compound identification was done. Then, it continues with data distribution which is boxplot. In this paper, the statistical works were executed via Matlab software. There are two parameters that required in this study which are the abundance of significant compound (%) and the species of citronella oil either C.nardus, C.winterianus or C.martinii. The result showed that, there is clearly can be seen the parameters through the boxplot analysis for data distribution. The techniques also confirmed their potential in statistical analysis for citronella oil significant compounds and proved that the data is applicable for further work especially for classification.
