title: [Chemical study of Alpinia officinarum].
abstract: Seven compounds were isolated from Alinia officinarum Hance and were identified as beta-sitoterol, 1,7-diphenyl-5-ol-3-heptone, 1-phenyl-7-(3'-methoxyl-4'-hydroxyl) phenyl-5-ol-3-heptone, glandin, kaempferol-4'-methylether and 3,4-dihydroxylbenzoic acid by IR, 1HNMR, 13CNMR, FAB-MS and EA. Among these compounds, 3,4-dihydroxylbenzoic acid was the first time obtained from Alpinia officinarum Hance. Furthermore, 1-phenyl-7-(3'-methoxyl-4'-hydroxyl) phenyl-5-ol-3-heptone and a new compound 1,7-diphenyl-3,5-heptandiol-phenyl-7-(3'-methoxyl-4'-hydroxyl) phenyl-3,5-heptaxdiol were obtained from 1,7-diphenyl-5-ol-3-heptone and 1-phenyl-7-(3'-methoxyl-4'-hydroxyl) phenyl-5-ol-3-heptone via chemical reductions.
