摘要
应用硅胶柱色谱,Sephadex LH-20柱色谱及高效制备薄层色谱等方法对沙滩黄芩中的二萜单体进行分离纯化,根据理化性质和波谱数据对其化学结构进行阐明,发现并鉴定了9个二萜化合物,分别为6-乙酰氧基-7-烟酸酰氧基半枝莲碱G(1),6-烟酸酰氧基-7-乙酰氧基半枝莲碱G(2),6,7-二烟酸酰氧基半枝莲碱G(3),半枝莲碱K(4),半枝莲碱B(5),6-乙酰氧基河南半枝莲碱A(6),6-烟酸酰氧基半枝莲素A(7),6,7-二乙酰氧基半枝莲素A(8),半枝莲碱F(9)。化合物1为新化合物,化合物2~9均为首次从沙滩黄芩中发现。
By means of preparative HPTLC and column chromatography over silica gel and Sephadex LH-20, nine diterpenoids were isolated and purified from the whale plants of Scutellaria strigillosa. Based on the physico-chemical properties and spectral data, their structures were elucidated as: 6-O-acetyl-7-O-nicotinoylscutebarbatine G( 1 ) , 6-O-nicotinoyl-7-O-acetylscutebarbatine G(2) , 6,7-di- O-nicotinoylscutebarbatine G (3), scutebarbatine K (4), scutebarbatine B (5), 6-O-acetylscutehenanine A ( 6), 6-O-nicotinoylbarbatin A(7), 6,7-di-O-acetoxylbarbatin A(8), scutebarbatine F(9). Compound 1 is a new diterpenoid, and compounds 2-9 were isolated from Scutellaria strigillosa for the first time.
