Six new diarylheptanoids, 5-hydroxy-7-(4-hydroxyphenyl)-1-(4-hydroxy-3-methoxyphenyl)-3-heptanone, 3,5-diacetoxy-7-(3,4-dihydroxyphenyl)-1-(4-hydroxy-3-methoxyphenyl)heptane, 5-hydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl) -7-(4-hydroxy-3-methoxyphenyl)-3-heptanone, 5-hydroxy-7-(4-hydroxy-3,5-dimethoxyphenyl)-1-(4-hydroxy-3-methoxyphenyl) -3-heptanone,(3R,5S)-3,5-dihydroxy-1,7-bis (4-hydroxy-3-methoxyphenyl)heptane and (3S,5S)-3,5-diacetoxy-1,7-bis(3,4-dihydroxyphenyl)heptane were isolated from the rhizomes of Zingiber officinale, together with two known diarylheptanoids. Their structures were established by chemical and spectroscopic evidences.
