Study on the GC Fingerprint of Volatile oil of Dalbergia odorfera

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.
