| Abstract | The result showed total phenolic content, total flavonoid content and radical scavenging activity in ethanol extractshigher than oil extracts and massage products of Boesenbergia rotunda, Alpinia conchigera, Alpinia galangal, and Alpiniasiamensis. Fourier-transform infrared spectroscopy of the ethanol extracts provided specific peaks in a range of 4,000 to 550 cm1. Chemical differentiation between Alpinia sp. and Boesenbergia sp. was indicated by main peaks that corresponded to aromaticand N-H in amino acids, O-H in phenyl group, and C-O in carbohydrates and glycoprotein. Chemical differentiation among threeAlpinia species were wavenumber ranges of C-O in acid or ester, C-O in carbohydrates and glycoprotein, and C-H inisoprenoids. The cluster and PCA analysis showed good separation of chemical compositions and antioxidant activity among theethanol extract, massage solution and oil extract. Additionally, Ni, and Cd were found in all massage products, especially Niabove its maximum permission level. |
