| Abstract: | "Alpinia galanga Wild.(L.) is well known for its aromatic constituents. Though the aromatic composition is already known, but lots of constituents which contributing overall aroma of the oil are still unknown due to the co-eluting factor of single column in GC-MS. Thus the current study aims to characterise maximum volatile constituents present in the essential oil of A. galanga using thermal desorption modulator of two-dimensional gas chromatography and time-of-flight mass spectrometry. The 102 compounds with good match and high probability value were identified out of which 42 were identified for the first time. The total identified compounds include 47 hydrocarbons 25 alcohols, 7 ketones, 7 esters, 3 aldehyde, 4 ethers and 9 other classified aromatic compounds. It was further categorised into Monoterpene Hydrocarbons, Oxygenated Monoterpenes, Sesquiterpene Hydrocarbons and Oxygenated Sesquiterpenes. The major constituent also varies with respect to area percentage. The in-depth characterisation will help in its qualitative analysis" |
