Two new diarylheptane derivatives were isolated from Rhizoma Zingiberis by Diaion HP-20, MCI Gel CHP-20, ODS, silica gel column and reverse phase semi-prepared high performance liquid chromatography. Their structures were elucidated by spectrum technology (MS, UV, IR, NMR), which were identified as 3-keto-5R-ethoxy-1-(3-methoxy-4-hydroxyphenyl)-7-(3, 4-dihydroxyphenyl)heptane (1) and 3-keto-5R-ethoxy-1-(3-methoxy-4-hydroxyphenyl)-7-(3-methoxy-4, 5-dihydroxyphenyl)heptane (2). Compounds 1 and 2 are new compounds.
