摘要: 利用各种色谱技术对黑紫橐吾的乙酸乙酯萃取部位进行分离纯化, 并且根据一维和二维波谱数据进行结构鉴定. 共分离得到4个呋喃雅槛蓝型倍半萜: 1α-氯-6β-异丁酰基-9-酮-10β-羟基-呋喃雅槛蓝烷(1), 1α-羟基-6β-异丁酰基-9-酮-10β-氢-呋喃雅槛蓝烷(2), 1α-羟基-6β-异丁酰基-9-酮-10α-氢-呋喃雅槛蓝烷(3)和1α,10β-二羟基-6β-当归酰基-9-酮-呋喃雅槛蓝烷(4). 其中化合物1为新化合物, 并且通过X射线单晶衍射确定了绝对构型; 化合物2~4为首次从该植物中分离得到.

Abstract: A new and three known furanoeremophilanes were separated from Ligularia atroviolacea via chemical investigation, which were identified as 1α-chloro-6β-isobutyroxy-9-oxo-10β-hydroxy-furanoeremophilane(1), 1α-hydroxy-6β-isobutyroxy-9-oxo-10β-H-furanoeremophilane(2), 1α-hydroxy-6β-isobutyroxy-9-oxo-10α-H-furanoeremophilane(3), 1α,10β-dihydroxy-6β-angeloyloxy-9-oxo-furanoeremophilane(4). Their structures were established by spectroscopic methods including 2D-NMR. The absolute structure of compound 1 was determined by X-ray diffraction analysis.

Key words: Ligularia atroviolacea, Isolation and purification, Structure identification, Furanoeremophilane, X-ray diffraction
