| Summary: | Cymbopogon citratus or also known as lemongrass, is a fast-growing species can be
found abundantly in all houses such as in Sarawak. The unique characteristics of its
chemical compound enhance the possibility of producing safer insect repellent to
overcome the side effects of synthetic insect repellent. In this study, a comparison of
various solvents used in extraction as well as the extraction parameters (extraction time
and extraction temperature) has been studied to determine the suitable condition for
extracting the essential oil from Cymbopogon Citratus. Apart from that, the suitability of
models (Pseudo First Order Model and Pseudo Second Order Model) to describe the
kinetic analysis of extraction together with process optimization using Response Surface
Methodology (RSM) also been conducted. By the end of this study, extraction using
Soxhlet extraction found that water was chosen as the most suitable solvent in extracting
essential oil from Cymbopogon Citratus and based on the FTIR characterization of the
extracted essential oil, all three solvents (water, ethanol and n-hexane) able to extract the
main active compound with repellent properties(geranial and neral under aldehyde group
and citronellos and geraniol under aliphatic alcohol group). Pseudo First Order Model
and Pseudo Second Order Model as well as the RSM model able to predicts the extraction
kinetic together with process optimization with the value of T=51.27°C and t=8h which
resulting a 74% of extracted essential oil. |
