Linalool, which is a dominant compound in coriander essential oil, was the most abundant volatile compound in all extracts obtained at 100 and 150 °C, however, it almost completely degraded at 200 °C.
The level of hexanal, being the most abundant volatile compound (about 60%% of total volatile concentration) in both cultivars, stored at 16 °C did not show an appreciable change.
D-limonene was the most abundant volatile compound which accounted for 80.8% and 64.4% of the volatile profile in Murcott and Temple, respectively.
Water was extracted from samples via cryogenic vacuum distillation [33], with addition of activated charcoal to remove abundant volatile organic compounds and subsequent filtering to remove particulates.
Methanol is the second most abundant volatile organic compound in the troposphere and plays a significant role in atmospheric chemistry.
Methanol (CH3OH) is, on average, the second most abundant volatile organic compound (VOC) in the troposphere (Jacob et al., 2005), with typical mole fractions in the continental boundary layer of 1 10 nmolmol−1 (Heikes et al., 2002).
The review paper summarized a total of 144 compounds and abundant volatile components that were reported from the genus Elsholtzia, with 117 references cited.
Previously, many studies indicated that estragole is the most abundant of the A. rugosa essential oil volatile compounds ranging from 56-94% [ 8].
In our study, 2-AP had the highest average relative content among the detected compounds in Yuxiangyouzhan, while was the the third most abundant volatile detected in Nongxiang 18. Octanal had the second higher average relative content among the detected compounds in both varieties.
M. citrifolia contains highly volatile compounds that confer toxicity (Legal 1994), with the two most abundant being octanoic acid (58%) and hexanoic acid (19.24%) (Farine 1996).
