Chromatographic separation of part of an EtOH extract of the seeds of Alpinia blepharocalyx resulted in the isolation of six new (1-6) and two known (7, 8) diarylheptanoids together with 12 known compounds. The structures of the new compounds, including their absolute stereochemistry, were elucidated by spectroscopic and chemical methods as (3S,5S)- (1) and (3S,5R)-3-hydroxy-5-methoxy-1-(4-hydroxyphenyl)-7-phenyl-6E-heptene (2), (3S,5S)- (3) and (3S,5R)-3-hydroxy-5-ethoxy-1-(4-hydroxyphenyl)-7-phenyl-6E-heptene (4), (3S)-methoxy-1,7-bis(4-hydroxyphenyl)-6E-hepten-5-one (5), and 1,7-bis(4-hydroxyphenyl)hepta-4E,6E-dien-3-one (6). Among the isolated compounds, 5, (3S,5S)-3,5-dihydroxy-1,7-bis(4-hydroxyphenyl)heptane (8), 4'-hydroxy-5,6-dehydrokawain (14), and/or phloroglucinol (20) showed significant antiproliferative activity against murine colon 26-L5 carcinoma (ED(50): 5, 5.2 microM; 8, 12.8 microM; 14, 20.7 microM; 20, 26.4 microM) and human HT-1080 fibrosarcoma (ED(50): 5, 10.1 microM; 14, 20.1 microM; 20, 20.9 microM) cells.
