Study on the Specific GC Chromatograms of Volatile Oil from Xinyi Biyan Pills

摘要

[Objectives]This study was conducted to establish characteristic chromatograms of of the volatile oil of Xinyi Biyan Pills by gas chromatography,discover possible problems in the production processes of different manufacturers,and further improve the quality control methods.[Methods]The volatile oil in samples was extracted and tested by gas chromatography to collect chromatograms,which were analyze and evaluated by the similarity evaluation software of chromatographic fingerprints of traditional Chinese medicine.[Results]Nineteen common peaks were calibrated in the characteristic chromatograms;and the characteristic chromatograms of samples produced by different manufacturers were obviously different.[Conclusions]Controlling the volatile components in Xinyi Biyan Pills by the established characteristic chromatograms of GC is accurate and feasible,and can be used as a quality control method for Xinyi Biyan Pills.
