Abstract

Microwave-Assisted Hydrodistillation (MAHD) is an advanced technique for extraction process, in which microwave heating process is used. MAHD and hydrodistillation (HD) methods have been studied and the results were compared for their effectiveness in the extraction of essential oils from patchouli leaves. In present study the MAHD methods was operated with some levels of electrical power. The results showed that MAHD methods can reduce the extraction time and increase the yield. MAHD was also found to be a green technology since it required less energy than HD. The energy consumption of HD is 30% higher than MAHD. The results also indicated that power levels of MAHD have significant effect on ultimate extraction yield and time consumption. The higher power of MAHD can obtained higher ultimate yield.
