目的运用气相色谱-质谱联用技术对党参Codonopsis pilosula （Franch.） Nannf、素花党参Codonopsis pilosula Nannf.var. modesta （Nannf.） L. T. Shen及川党参Codonopsis tangshen Oliv.的游离糖成分进行分析鉴定。方法采用震荡提取法从党参中提取多种游离糖化合物,游离糖成分经乙酰化后利用气相色谱-质谱法分析其组成、结构。结果通过气相色谱-质谱分析结合标准品数据以及相关文献,鉴别出3种党参中7种游离糖成分,分别为山梨糖、半乳糖、葡萄糖、D-甘露糖、果糖、肌醇、蔗糖,游离糖含量存在差异。结论气相色谱-质谱联用技术可以对党参游离糖成分进行定性及定量分析,为党参品质分析提供科学依...

Objective To identify the free sugar components in three species of Codonopsis[Codonopsis pilosula(Franch.)Nannf.,Codonopsis pilosula Nannf.var.modesta(Nannf.)L.T.Shen,and Codonopsis tangshen Oliv.]by gas chromatography-mass spectrometry(GC-MS).Methods A variety of free sugar compounds were extracted from Codonopsis by shaking extraction.The composition and structure of free sugar components were analyzed by GC-MS after acetylation.Results Seven free sugar components were identified in the three species of Codonopsis by GC-MS according to the data of reference standard and the relevant literat...
