Abstract: Objective: Extraction and purification of chemical constituents in the ginger plant Kaempferia galanga. Methods and Results: Kaempferia galanga 95% ethanol extract silica gel column chromatography, eluting with petroleum ether / ethyl acetate, methylene chloride extract fractions eluted with petroleum ether / ethyl acetate system. Compound A, B, C, D. Conclusion: A, by the carbon spectra and NMR spectra verify that proved to be the methoxy ethyl cinnamate B NMR spectra to verify that the methoxy cinnamic acid. C, D, by vanillin in concentrated sulfuric acid blue-green spots, the iodine color is a purple point, proved to be monomers.
Keywords: Kaempferia galanga Linn; single component; silicon column; petroleum ether / ethyl acetate system; vanillin in concentrated sulfuric acid
