降香挥发油GC指纹图谱的研究

Study on the GC Fingerprint of Volatile oil of Dalbergia odorfera

摘要: 目的建立降香挥发油指纹图谱分析方法，比较不同地区商品降香药材的质量。方法 GC-FID建立指纹图谱，图谱采用“中药色谱指纹图谱相似度评价系统”软件进行分析和相似度计算，利用GC-MS和文献对照检识共有峰的成分。结果指纹图谱的分离度较好，指认了21个共有峰，根据相似度计算结果对不同地区的30批商品降香进行了评价，将降香药材分成三类，降香质量差异较大。结论降香挥发油指纹图谱特征性强，方法重复性好，可定性用于全面控制降香的质量。

Abstract: OBJECTIVE To establish chromatographic fingerprint of volatile oil and investigate the variance of Dalbergia odorfera collected from different palces. METHODS The fingerprint was established by GC-FID, and evaluated by “Computer Aided Similarity Calculation”. The characteristic peaks in chromatograms were identified by GC-MS and literatures. RESULTS The fingerprint of Dalbergia odorfera was obtained, 21 common peaks were identified. The 30 batches of Dalbergia odorfera from different palces were classified into three types based on the results of similarity analysis. The quality of Dalbergia odorfera samples were quite different. CONCLUSION The convenient and high specific method can be used to identify and evaluate the quality of the Dalbergia odorfera.
