Abstract

The main pungent principles and essential oils of West Indian ginger (Zingiber officinale Roscoe) were identified and quantified by liquid chromatography. The stationary phase used was (5.0 g silica gel 70–230 mesh) and the mobile phase [petroleum ether (60–80°C) : diethyl ether (3 : 7 v⧸v)]. The first 15 ml contained the very volatile and least polar compounds present in the extracted oleoresin from the solar dried ginger rhizome. These compounds are the essential oils (Rf = 0.90) and 25.63% (w⧸w) of the total oleoresin charge to the column. The next 5 ml aliquot was without any compounds. The following 25 ml contained the shogaol fraction (Rf = 0.42) and 47.74% (w⧸w) of the total oleoresin charge to the column. The next 5 ml aliquot was without any compounds. The following 35 ml contained the gingerol fraction (Rf = 0.20) and 27.13% (w⧸w) of the total oleoresin charge to the column. This simple liquid chromatography method can be used to investigate the essential oils and pungent principles of the extracted oleoresin from the solar dried ginger rhizomes.
