目的:对百合科植物大叶黄精(Polygonatum kingianum var.grandifolium)干燥根茎石油醚萃取部位的化学成分进行分离与鉴定.方法:大叶黄精药材经提取、萃取得石油醚部位,用硅胶、ODS 柱色谱法及半制备高效液相色谱法等分离化合物,运用 NMR 技术等鉴定化合物结构.结果:共分离得到6个化合物,分别鉴定为甲基麦冬二氢黄酮 B(1)、白及内酯(2)、十五烷酸(3)、豆蔻酸(4)、天竺葵酸(5)和十三烷酸乙酯(6).结论:化合物1~6首次从大叶黄精中分离得到.
Isolation and Identification Chemical Components of the Petroleum Ether Extracted Part from the Rhizoma of Polygonatum Kingianum var.Grandifolium
Objective:To isolate and identify chemical components of the petroleum ether extracted part from the rhizoma of Polygonum kingianum var.grandiflorum,a plant of the Liliaceae.Method:The dried rhizoma of Polygonum kingianum var.grandiflorum were extracted and partitioned to yield the petroleum ether extracted fraction,and it was subjected to silica gel and octadecylsilyl column chromatography,and then separated by high performance liquid chromatography to yield compounds,which were identified by spectral analysis of nuclear magnetic resonance spectra.Result:Six compounds were obtained and identified as Methylophiopogonanone B(1),Striatoliode(2),Pentadecanoic acid(3),Myristic acid(4),Nonanoic acid(5)and Ethyl tridecanoate(6).Conclusion:Compounds 1~6 were for the first time from the titled plant.
