板蓝根化学成分

Isolation and Identification of Chemical Constituents from Isatis indigotica

摘要:

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。

Abstract:

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 by¹H,¹³C-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.
