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, 1'S-1'-acetoxychavicol acetate (1) and p-coumaryl alcohol $\gamma$-O-methyl ether (2). 1'S-1'-acetoxychavicol acetate (1) exhibited significant cytotoxicity against all human cancer cell lines tested (A549; $IC_{50}$ 8.14, SNU 638; 1.27, HCTl16; 1.77, HT1080; 1.2, HL60; $IC_{50}$ 2.39 ${\mu}g/ml$), whereas p-coumaryl alcohol $\gamma$-O-methyl ether (2) showed selective cytotoxicity against the SNU638 cell ($IC_{50}$ = 1.62${\mu}g/ml$).
