【摘要】 从高良姜乙醇提取物中分离得到7个化合物。经光谱分析分别鉴定为β-谷甾醇(Ⅰ)、1,7-二苯基-5-醇-3-庚酮(Ⅱ)、1-苯基-7-(3′-甲氧基-4′-羟基)苯基-5-醇-3-庚酮(Ⅲ)、高良姜素(Ⅳ)、山萘素(Ⅴ)、山萘素-4′-甲醚(Ⅵ)和3,4-二羟基苯甲酸(Ⅶ),其中Ⅶ是首次从高良姜中分离得到。Ⅱ、Ⅲ经化学还原修饰后得到1,7-二苯基-3,5-庚二醇(Ⅷ)和1-苯基-7-(3′-甲氧基-4′-羟基)苯基-3,5-庚二醇(Ⅸ),其中Ⅸ是新化合物。更多还原

【Abstract】 Seven compounds were isolated from Alpinia officinarum Hance and were identified as β-sitoterol,1,7-diphenyl-5- ol-3-heptone,l-phenyl-7-（3’-methoxyl-4’-hydroxyl）phenyl-5-ol-3-heptone,glandin,kaempferol,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.更多还原
