 "Four isomers of acetoxycineoles, (trans and cis)-2- and 3-acetoxy-1,8-cineoles, were identified as the odorous components of the rhizomes of greater galangal. Their structures were confirmed by comparing the retention indices by GC and the mass spectra with those of synthesized compounds. The concentration of trans-3-acetoxy-1,8-cineole was the highest among the isomers. The isomers presented individual odor features:  the (trans and cis)-2 isomers respectively exhibited woody and sweet aromas, while the (trans and cis)-3 isomers respectively showed sweet floral and camphoraceous aromas. Of these, trans-2-acetoxy-1,8-cineole seemed to have the strongest qualitative effect on the characteristic flavor of greater galangal." \\

 "The pungent principal of galangal [Alpinia galangal (L.) Swartz] rhizomes was isolated and identified as 1‘-acetoxychavicol acetate ([[http://www.leffingwell.com/chirality/galangal_acetate.htm|galangal acetate]]). Galangal acetate exhibits a unique pungent sensation, which is less intense than that of capsaicin and without a lingering effect... Galangal acetate is not stable in aqueous solutions and undergoes hydrolysis/isomerization reactions. Therefore, galangal acetate was absent in galangal essential oil obtained by steam distillation. However, galangal acetate was found as one of the major volatile components of the galangal rhizomes by headspace GC analysis.  " \\

 "The essential oils of the leaves, stems, rhizomes and roots of the medicinal plant Alpinia galanga from southern India were investigated by GC-FID, GC-MS and olfactometry. In all four samples, mono- and sesquiterpenes as well as (E)-methyl cinnamate could be identified. They are responsible for the characteristic odor as well as for the reported use in (folk) medicine and in food products of A. galanga

 The acetone and ethanolic extracts of A.galanga were active in axenic (aerobic and anaerobic) and intracellular assays to determine the antimycobacterial potential. The aqueous extract did not demonstrate activity under the defined assay parameters. All three extract contained acetoxychavicol acetate. \\
 "A. galanga exhibits anti M.tb activity with multiple modes of action. Since the activity of the extracts was observed under reducing oxygen concentrations, it may be effective in treating the dormant and non-replicating bacteria of latent TB. Though the hypothesis needs further testing, A. galanga being a regular dietary component may be utilized in combination with the conventional TB therapy for enhanced efficacy." \\
