板蓝根化学成分

Isolation and Identification of Chemical Constituents from Isatis indigotica

目的:研究板蓝根的化学成分。方法:运用多种层析分离手段,通过1H,13C-NMR等波谱技术及理化数据鉴定化合物的结构。结果:从板蓝根中分离并鉴定了6个化合物,分别为正二十一烷酸,β-谷甾醇,靛玉红,腺嘌呤核苷,大黄素及fructopyrano-(1→4)-glucopyranose。结论:正二十一烷酸和fructopyrano-(1→4)-glucopyranose均是首次从板蓝根中分离得到。

Objective： TO study chemical constituents from Isatis indigotica. Method： Chemical constituents were isolated by many chromatographic separation method, and structure of these were identified by purified by 1^H,13^ C-NMR and other spectroscopy technology and physicochemical data. Result： Six compounds were isolated and identified as n-heneicosanoic acid, β-sitosterol, indirubin, adenosine, emodin, Fructopyrano- （1→4） -glucopyranose. Conclusion ： N-heneicosanoic acid and Fructopyrano- （1→4） -glucopyranose were first isolated from I. indigotica.
