Abstract

In this research, microwave-assisted hydrodistillation (MD) with pretreatment ultrasound (US) 45 and 90 min of essential oils from fresh Aegle marmelos peel were used and the results were compared with those obtained by hydrodistillation technique (HD) in terms of extraction yield/efficiency, extraction time, chemical composition and quality of the essential oil. All experiments were performed with at least three replicates. They were done according to GLM method and LSD Test in the SAS software system. The values obtained for essential oil from Aegle marmelos was achieved 2.00±0.2% and 1.97±0.2% by MD with pretreatment US (45 and 90 min) and 2.02±0.2% by MW. By using GC-MS system the compositions of essential oils extracted were identified. The major component of essential oils obtained by both methods was limonene. There is no significant effect on the yield of essential oil and quality of essential oils extracted by MD with pretreatment US as compared to MW method.
