Extraction and characterization of essential oil from ginger (Zingiber Officinale Roscoe) and lemongrass (Cymbopogon Citratus) by microwave-assisted hydrodistillation (MAHD)

Microwave-assisted hydrodistillation (MAHD),an advanced distillation method that take advantage of microwave heating with the conventional hydrodistillation,recently been widely attended for the extraction of essential oil from medicinal plants and herbs due to its economic and green technology.
