摘要(Abstract):

目的:研究茜草科粗叶木属植物长尾粗叶木Lasianthus acuminatissimus根中的化学成分。方法:利用正相、反相(RP-18)硅胶柱色谱、大孔树脂柱色谱和制备高效液相色谱分离,通过现代波谱技术(13C-NMR,1H-NMR,DEPT,EI-MS)鉴定结构。结果:分离鉴定了6个化合物,分别为:异东莨菪素(isoscopletinⅠ),异东莨菪素6-O-β-D-葡萄糖苷(isoscopletin-6-O-β-D-glucopyranosideⅡ),mudanoside-A的β构型体(Ⅲ),车叶草苷(asperulosideⅣ),(-)-pinoresinol 4-O-β-D-glucopyranoside(Ⅴ),胡萝卜苷(Ⅵ)。结论:这些化合物均是首次从粗叶木属植物中得到。
Objective: To investigate the chemical constituents from the root of Lasianthus acuminatissimus of Rubiaceae.Method: Normal,reverse phase silica gel,macroporous resin column and HPLC chromatography were used for isolation.Spectroscopic methods((13)CNMR,()(13)CNMR,()1H-NMR,DEPT,EI-MS) were used for identification.Result: Six compounds were isolated and elucidated as isoscopletin(Ⅰ),isoscopletin-6-O-β-D-glucopyranoside(Ⅱ),β configuration of Mudanoside-A(Ⅲ),asperuloside(Ⅳ),(-)-pinoresinol 4-O-β-D-glucopyranoside(Ⅴ),daucosterol(Ⅵ).Conclusion: These compounds were obtained from this plant for the first time.
