三种黄精炮制前后呋喃类化学成分的变化

Changes of Furan Constituents in Rhizome of Three Species of Polygonatum Before and After Processing

目的:建立顶空静态进样快速分析黄精炮制前后呋喃类成分的GC-MS方法。方法:采用顶空静态进样技术提取黄精的挥发性成分进行GC-MS研究,并对3种黄精不同炮制前后的呋喃类成分进行GC-MS半定量测定。结果:3种黄精中呋喃类成分含量差异显著,多花黄精≈滇黄精>黄精。炮制后各种黄精中9种呋喃类成分多有所增加,蒸制品>炆制品。结论:该结果为黄精炮制过程的进一步研究提供了理论依据。

Objective ： To establish a rapid analytical method for furan components before and after processing of Polygonatum rhi- zome by static headspace injection GC-MS. Methods：The volatile components were extracted by headspace injection technique and ana- lyzed by GC-MS, and the furan components of three species of Polygonatum rhizome before and after processing were determined by semi quantitative GC-MS. Results ： Three species of Polygonatum rhizome had significant differences in furan components contents, Po- lygonatum cyrtonema ≈ Polygonatum kingianum 〉 Polygonatum sibiricum. Each species of Polygonatum rhizome had a corresponding in- crease in almost all of the nine kinds of furan components after processing, steamed products 〉 stewed products. Conclusion：This study provides a theoretical basis for further study of processing of Polygonatum rhizome.
