利用高效液相色谱和电喷雾质谱指纹图谱鉴别人参与桔梗

Identification of Panax Ginseng and Platycodon Grandiflorum by the Fingerprint of HPLC and ESI-MS

摘要: 用高效液相色谱和电喷雾质谱建立人参、桔梗的色谱和质谱指纹图谱，通过两种中药材指纹图谱的差异，达到鉴别中药材真伪的目的。建立的质谱指纹图谱方法简捷、快速、灵敏、特征性强、重现性好，具有很好的实用价值。

Abstract: The fingerprint of Panax ginseng and Platycodon grandiflorum were estableshed using HPLC and ESI-MS. By comparing the fingerprint difference between two Chinese herbs, Panax ginseng and Platycodon grandiflorum are identified. The method of ESI-MS fingerprint is simple, fast, sensitive, stable and accurate. So the ESI-MS fingerprint has wider practical value.
