【摘要】 目的进一步研究毛茛科植物黄花乌头 Aconitum coreanum的化学成分 ,寻找更多有活性的生物碱类物质。方法采用乙醇提取、溶剂萃取、氧化铝柱色谱方法进行分离纯化有关成分 ,根据理化性质和谱学分析 (IR,ESI-MS,1 H- NMR,1 3C- NMR,1 H- 1 HCOSY,HMQC,HMBC)进行结构鉴定。结果从黄花乌头根中分离得到 7个化合物 ,分别鉴定为 :11,13-二乙酰基 - 14 -羟基 - 2 -异丁酰基 -赫替新 (11,13- diacetyl- 14 - hydroxy- 2 -isobutyryl heti- sine,I)、关附庚素 (guan- fu base G, )、关附己素 (guan- fu base F, )、关附 Z素 (guan- fubase Z, )、关附壬素 (guan- fu base I, )、关附子素 (guan- fu base K, )、关附胺醇 (guan- fu aminealcohol, )。结论化合物 I为新天然产物 ,命名为关附巳素 (guan- fu base P) ,首次报道其氢谱和碳谱数据。更多还原

【Abstract】 Object To search for more bioactive alkaloids from Aconitum coreanurn through this fur-ther study. Methods The ethanolic extract from the root of A. coreanum was isolated by aluminium oxidecolumn chromatography, the constituent structures were elucidated mainly by their physicochemical prop-erties and spectroscopic (IR, ESI-MS,1 H-NMR, 13 C-NMR,1 H-1 HCOSY, HMQC, and HMBC)analysis.Results Seven alkaloids were obtained from the root of A. coreanum, they were identified as: 11, 13-di-acetyl-14-hydroxy-2-isobutyryl hetisine ( Ⅰ ), guan-fu base G ( Ⅱ ), guan-fu base F ( Ⅲ ), guan-fu base Z( Ⅳ ), guan-fu base I ( Ⅴ ), guan-fu base K ( Ⅵ ), and guan-fu aminealcohol (Ⅶ). Conclusion Compound I is a new natural product, named as guan-fu base P, its 1 H-NMR and 13 C-NMR data are reported first inthis paper.更多还原
