| 摘要: |
| 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据。 |

| Abstract: |
| 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 literature, including sorbose, galactose, glucose, D-mannose, fructose, inositol, and sucrose. There were differences in the content of these free sugar components between the three species of Codonopsis.Conclusion GC-MS can be used for the qualitative and quantitative analysis of free sugar components in Codonopsis. It can provide a scientific basis for the quality analysis of Codonopsis. |
