Background Hydro-distillation (HD) method is a traditional technique which is used in most industrial companies. Microwave-assisted Hydro-distillation (MAHD) is an advanced HD technique utilizing a microwave oven in the extraction process. Methods In this research, MAHD of essential oils from the aerial parts (leaves) of rosemary (Rosmarinus officinalis L.) was studied and the results were co...

In this study, extraction of essential oil, polyphenols and pectin from orange peel has been optimized using microwave and ultrasound technology without adding any solvent but only "in situ" water which was recycled and used as solvent. The essential oil extraction performed by Microwave Hydrodiffusion and Gravity (MHG) was optimized and compared to steam distillation extraction (SD). No signif...

The aim of this work is to compare the extraction efficiencies of microwave and conventional isolation of mangiferin from Mangifera indica L. The parameters studied, which might affect the extraction efficiency were extraction time, solvent composition and microwave power. The conventional heating 21 h provided 5.23 % yield of mangiferin and by microwave heating at 210 W for 56 min, the yield w...
