Microwave assisted extraction (MAE) was a commonly used
sample preparation technique for the extraction of organic contaminants
from solid matrix (Satpathy, Tyagi, & Gupta, 2011). With
the development of ‘‘green extraction’’ methods, ‘‘green microwave
extraction’’ methods have been frequently reported such as solvent-
free microwave extraction (SFME) (Li et al., 2012), microwave
hydrodiffusion and gravity (MHG) (Bousbia et al., 2009) and microwave-
assisted hydrodistillation (MAHD) (Golmakani & Rezaei,
2008). These methods have been applied on the isolation of volatile
compounds from natural plants. In these methods, the extraction
procedure was carried out utilising the water inside the plant issues,
which was heated up and caused the cell rupture and dropping
of the extracts (Li et al., 2012). The remarkable benefits of
these methods were rapidity and low organic solvent consumption.
However, these methods were not suitable for the extraction
of compounds from samples in which the moisture content was
low. To overcome the restriction, microwave assisted steam distillation
(MASD) (Numata, Yarita, Aoyagi, & Takatsu, 2003) and
microwave-assisted water steam extraction (MASE) (Song et al.,
2012) were developed. For MASD, the sample soaked up water in
a few minutes before extraction and nonpolar organic solvents
were used to absorb the analytes. For MASE, the analytes could
be extracted without soaking the low-moisture content samples
before extraction, and the benefits of rapidity and low organic solvent
consumption were maintained
