| Abstract: | The chromatographic fingerprint for the characterization of the volatile components of Forsythia suspensa (Thunb.) Vahl has been developed. Volatile components from different regions were extracted by steam distillation, and the chromatographic fingerprint were characterized by capillary gas chromatography, The fuzzy cluster was selected to compare the results. This method gave high sensitivity, good reproducibility and good stability. The chromatographic overlap ratio of samples were over 97%. An analysis of the combination of chromatographic fingerprint and fuzzy cluster is convenince and accuracy. It is suitable for the quality control of Forsythia suspensa (Thunb.) Vahl. |
