德钦乌头块根化学成分的研究

Chemical constituents from the roots tuber of Aconitum ouvrardianum

目的研究德钦乌头Aconitum ouvrardianum H.块根的化学成分。方法德钦乌头块根甲醇提取物的乙酸乙酯部位采用硅胶、氧化铝色谱柱、Sephadex LH-20进行分离纯化,根据理化性质和波谱数据鉴定所得化合物的结构。结果从中分离得到18个化合物,分别鉴定为工布定(1)、anisoezochasmaconitine(2)、lipo-14-O-anisoylbikhaconine(3)、大渡乌碱(4)、塔拉萨敏(5)、查斯曼宁(6)、粗茎乌头碱甲(7)、查斯马可宁定(8)、14-dehydrotalatizamine(9)、lipoindaconitine(10)、印乌碱(11)、滇乌碱(12)、lipoyunaconitine(13)、贡乌生(14)、transconitine B(15)、ouvrardiantine(16)、atropurpursine(17)、8-去乙酰滇乌碱。结论化合物1~4、9~10、13、15、17为首次从该植物分离得到。

AIM To study the chemical constituents from the roots tuber of Aconitum ouvrardianum H..METHODS The ethyl acetate fraction of methy extract from A. ouvrardianum roots tuber was isolated and purified by silica,aluminium oxide column,Sephadex LH-20,then the structures of obtained compounds were identified by physicochemical properties and spectral data. RESULTS Eighteen compounds were isolated and identified as kongboendine（ 1）,anisoezochasmaconitine（ 2）,lipo-14-O-anisoylbikhaconine（ 3）,franchetine（ 4）,talatisamine（ 5）,chasmanine（ 6）,crassicauline A（ 7）,chasmaconitine（ 8）,14-dehydrotalatisamine（ 9）,lipoindaconitine（ 10）, indaconitine（ 11）, yunaconitine（ 12）, lipoyunaconitine（ 13）, liljestrandisine（ 14）,transconitine B（ 15）, ouvrardiantine（ 16）, atropurpursine（ 17）, 8-deacetylyunaconitine（ 18）.CONCLUSION Compounds 1-4,9-10,13,15,17 are isolated from this plant for the first time.
