摘要: 目的: 寻找柴胡与其混淆品小叶黑柴胡及锥叶柴胡的有效鉴别方法。 方法: 采取观察药材性状、根的横切面显微特征和薄层色谱的不同,对真品与混淆品加以鉴别。 结果: 真品与混淆品在上述三个方面均有着明显差别。 结论: 将药材性状的经验鉴别与显微或色谱方法相互结合,能有效地鉴别柴胡真伪。Abstract: Objective: To find the effective method to identify Bupleurum chinense and B. scorzoneraefolium with B. smithii wolff var. parvifolium Shan et Y. Li. and B.bicaule Helm. Methods: All the varieties including the confusion vartieties were identified by observing the shape and characters, comparing the transverse section microstructure of radix.TCL also was used to classify the varieties. Results: It is clearly that Bupleurum chinense DC. and B. scorzoneraefolium Willd. are different from B. smithii wolff var. parvifolium Shan et Y. Li. and B.bicaule Helm. Conclusion: Bupleurum chinense DC. and B. scorzoneraefolium Willd. can be effectively identified by experience identification,microscope and TCL.
