THE MAJOR VOLATILE COMPOUNDS OF CRUDE GINGER (ZINGIBER OFFICINALE ROSCOE) EXTRACTS FROM SUPERCRITICAL CO₂ EXTRACTION

This study aims to identify the major volatile compounds of crude ginger extracts from the supercritical carbon dioxide extraction.
Fresh ginger (Zingiber officinale Roscoe) rhizomes were peeled, sliced and dried in a rotary air dryer until containing the moisture content of 9.32±0.23%. Dried gingers were then pulverized to coarse powder approximately 0.5 mm diameter prior to extraction.
The supercritical carbon dioxide extraction of dried ginger was performed at the extraction column with the pressure of 200.0 bar, at the temperature of 35.0°C, followed by series of separation into the 1^st and 2^nd separating columns with the conditions of 60.0 bar, at 35.0°C and 50.0 bar, at 20.0°C, respectively.
Crude ginger extracts obtained from the 1^st and 2^nd separating columns were subsequently identified by using gas chromatography-mass spectrometry.
The major volatile compounds of crude ginger extracts were zingiberene (42.97%), AR-curcumene (8.69%), 1,8-cineole (2.58%) and zingerone (4.84% from the 1^st separating column, 14.46% from the 2^nd separating column).
