【摘要】 姜科植物姜黄(Curcuma longa)的块根称为黄丝郁金,是常用中药郁金的来源之一。为了研究黄丝郁金的利胆活性成分,采用柱色谱法对姜黄干燥块根的化学成分进行了研究。本文主要报道从中分离得到的1个喹啉类生物碱2-(2′-methyl-1′-propenyl)-4,6-dimethyl-7-hydroxyquinoline(1),7个没药烷型倍半萜2,5-dihydroxybisabola-3,10-diene(2),4,5-dihydroxybisabola-2,10-diene(3),turmeronol A(4),bisacurone(5),bisacurone A(6),bisacurone B(7)和bisacurone C(8),以及dehydrozingerone(9)和zingerone(10)的分离和鉴定。化合物1为一个新的生物碱类化合物,化合物6~8为首次从姜黄中分得,化合物9~10为首次从姜黄属植物中分离得到。更多还原

【Abstract】 One new quinoline alkaloid and seven known bisabolane sesquiterpenes: 2-(2′-methyl-1′-propenyl)-4,6-dimethyl-7-hydroxyquinoline(1),2,5-dihydroxybisabola-3,10-diene(2),4,5-dihydroxybisabola-2,10-diene(3),turmeronol A(4),bisacurone(5),bisacurone A(6),bisacurone B(7),bisacurone C(8),as well as dehydrozingerone(9) and zingerone(10) were isolated from the root tuber of Curcuma longa.Their structures were identified by spectral evidence.Compound 1 is a new compound,compounds 6-8 were isolated from this plant for the first time and compounds 9-10 from Curcuma for the first time.更多还原
