Solid phase microextraction and gas chromatography mass spectrometry analysis of Zingiber officinale and Curcuma longa

SPME analysis of Zingiber officinale Roscoe and Curcuma longa L. were performed by using a DVB/CARB/PDMS fiber. The SPME analysis of Zingiber officinale showed that the main components found were camphene (7.27%), geranial (8.37%), alpha-zingiberene (14.50%), alpha-farnesene (9.14%), beta-bisabolene (6.52%), and beta-sesquiphellandrene (9.92%). The SPME analysis of Curcuma longa showed that main components were p-cymene (12.96%) and ar-turmerone (12.08%). Other components were beta-phellandrene (7.86%), terpinolene (6.97%), ar-curcumene (8.53%), alpha-zingiberene (8.46%), and beta-sesquiphellandrene (7.37%). [GRAPHICS] .
