| Abstract |
This research aimed to extract essential oils from wild turmeric rhizomes and to analyze the chemical composition of the extracted essential oils by using gas chromatography-mass spectrometry (GC-MS). The microwave hydrodiffusion and gravity (MHG) method was applied to extract the essential oils by studying the effects of microwave power, extraction time and size of raw materials, and each factor was optimized by using response surface methodology (RSM). In addition, the independence and interaction effects were also evaluated. MHG and traditional hydrodistillation (HD) methods were compared in terms of extraction efficiency, energy consumption and chemical composition of the wild turmeric essential oils. The results showed that the optimal conditions for extraction of wild turmeric essential oils were microwave power of 720 W, extraction time of 40 min and size of raw materials of 5 mm, which provided an essential oil yield of 0.896 % (v/w). Regarding ANOVA, the results indicated that all independence parameters showed the significant effects of the extraction of essential oils. On the other hand, the square term of size of raw materials and interaction between microwave power and extraction time also represented the significant effects. In the GC-MS analysis, the results illustrated that the chemical compositions of wild turmeric essential oils extracted by MHG under the optimum conditions and HD were quite similar; namely, the major compounds of the essential oils in the two mentioned methods were Curzerene, α-Bergamotene, α-Cuparenol and α-Curcumene. Moreover, the comparison of extraction time on the yield of wild turmeric essential oils extracted by MHG and HD methods presented that MHG provided 0.896 % (v/w) in 40 min, while HD was 0.634 % (v/w) in 300 min. Additionally, the energy consumption in MHG, 0.48 kWh, which used lower than HD, 1.25 kWh. Therefore, the results can be concluded that the MHG method is more efficient, using lower extraction time and more saving energy when compared to HD. |
