摘要
采用高效液相色谱法,对云南临沧云县滇龙胆不同部位龙胆苦苷、獐牙菜苦苷、当药苷含量进行分析.结果显示:(1)龙胆苦苷、獐牙菜苦苷、当药苷在滇龙胆根、茎、叶、花中均有分布;龙胆苦苷、獐牙菜苦苷在根部含量较高,分别为(35.88±5.89)mg/g和(1.35±0.33)mg/g;当药苷在花部含量最高,为(0.97±0.24)mg/g.(2)不同部位有效成分间具有显著(P<0.05)或极显著(P<0.01)的相关性.(3)相同海拔条件下,不同栽培方式下滇龙胆根部龙胆苦苷含量差异不显著(P>0.05),但茎部、叶部獐牙菜苦苷含量差异显著(P<0.05).
With high performance liquid chromatography method,the contents of gentiopicroside,swertiapatens and sweroside in cultivation Gentiana rigescens were detected.The samples were collected from Lincang area.The result showed that gentiopicroside,swertiapatens,sweroside distribute in every part of Gentiana rigescens.Contents of gentiopicroside（35.88±5.89） mg/g and swertiapatens（1.35±0.33） mg/g were the highest in roots.Content of sweroside（0.97±0.24） mg/g was the highest in flowers.There was correlation in different effective constituents among different parts.（P〈0.05） or（P〈0.01）.Effective gentiopicroside content in roots were not significantly different among cultivation patterns（P〈0.05）.Content of swertiapatens was significantly different among cultivation patterns in stems and leaves（P〈0.05）.
