川白芷HPLC指纹图谱研究

Objective To provide the study of the quality of the medicinal plant Radix angelicae anomalae with new method and basis of assessment. Method To test the samples of Radix angelicae anamales by HPLC and assess them by such methods as the analysis of main components, cluster analysis and similarity assessment and to compare via fingerprint the samples used in different experiments in the cultivation of Radix angelicae anomalae. Result There exist significant differences between the finger-printing of sulphured samples and that of unsulphured ones and as the result the finger-prints of sulphured and unsulphured samples of this medicinal plant are established respectively. Conclusion The finger-print mentioned in this article epitomizes the characteristics of coumarin family of Radix angelicae anomalae and therefore this method can be used for the assessment of the quality of the medicinal plant and also for the distinction of whether the products of this plant are sulphured or not.
