A bioassay-guided fractionation of the n-hexane and chloroform extracts of the rhizomes of Alpinia galanga led to the isolation of two active compounds, l'S-l-acetoxychavicol acetate (1) and p-coumaryl alcohol τ-O-methyl ehter (2). 1'S'-1-acetoxychavicol acetate (1) exhibited significant cytotoxicity against all human cancer cell lines tested (A549; 8.14, SNU638; 1.27, HCT16; 1.77, HT1080; 1.2, HL60; IC50 2.39 μg/ml), whereas p-coumaryl alcohol τ-O0methyl ether (2) showed selective cytotoxicity against the SNU638 cell (IC_(50) value of 1.62μg/ml).
