| Summary: | Etlingera elatior is an aromatic plant with pharmacological activity including antioxidant, anticancer, antibacterial and anti-inflammatory. To extract the fragrance component effectively from the flower, a Microwave-assisted extraction method was used using ethanol as a solvent. The analysis of chemical compounds in the E. elatior flowers was required to identify the chemical compounds presented. The main objective was to determine the optimum condition to extract the highest yield of essential oil from the flower. Hence, different microwave power, time, and particle sizes of sample were studied to achieve the main objective. The response surface methodology (RSM) using Box-Behnken Design (BBD) were used to optimize the power (400, 600, 800W), time (2, 5, 8 minutes) and the average particle sizes (400, 500, 600μm) to achieve highest yield of essential oil. The optimum condition was achieved at the extraction power, time and average particle sizes of 508.78 W, 8 minutes and 400 μm, respectively with an oil yield of 7.40% and mass of ester of 365.25 μg ester/g sample. The GC-MS analysis was conducted to identify the composition of chemical compounds in the extracts. The study has successfully investigated the effect of parameters towards the fragrant overall yield and concentration of ester extracted. This study gave a better understanding of the suitable microwave extraction parameters for a commodity that is native to Malaysia for a potential product development involving fragrance and food product. © 2024 Author(s).
