Six diarylheptanoids, including three new compounds, were isolated from the rhizomes of Alpinia officinarum HANCE (Zingiberaceae). The structures of the new compounds were determined to be 7-(4"-hydroxyphenyl)-1-phenyl-4-hepten-3-one (I), 5-methoxy-7-(4"-hydroxyphenyl)-1-phenyl-3-heptanone (II), and 5-methoxy-1, 7-diphenyl-3-heptanone (III) on the basis of the spectroscopic data. This is the first time that compound IV, in which both phenyl rings are substituted, has been isolated from Alpinia spp.
从Alpinia officinarum HANCE(姜科)的根茎中分离出六种二芳基庚烷,包括三种新化合物。根据光谱数据,确定新化合物的结构分别为7-(4"-羟基苯基)-1-苯基-4-庚烯-3-酮(I)、5-甲氧基-7-(4"-羟基苯基)-1-苯基-3-庚酮(II)和5-甲氧基-1,7-二苯基-3-庚酮(III)。这是首次从Alpinia spp中分离出苯环均被取代的化合物IV。
