金丝桃属植物的HPLC指纹谱研究

目的 建立金丝桃属植物的HPLC指纹谱，对该属植物中所含的化学成分进行综合评价并为该属植物鉴定提供依据。方法 采用HPLC方法将获得的色谱数据转化为色谱指纹谱，据此对样品进行分折鉴别。结果 不同种金丝桃均显示了它们各自的指纹特征。结论HPLC指纹谱可以用来鉴别金丝桃属的不同种植物，该属植物种间的化学成分有较高的相似性，但各相应的成分含量差异显著。

Studies on HPLC fingerprint spectrum of plants from Hypericum Linn.

Object To establish HPLC fingerprint spectrum of plants from Hypericum Linn. to evaluate their chemical constituents and provide the scientific basis for identification. Methods HPLC results of the plants from Hypericum Linn.were transformed into HPLC fingerprint spectrum which was used to evaluate and distinguish the different plants of Hypericum Linn. Results The different plants from Hypericum Linn. showed different HPLC fingerprint spectrum. Conclusion HPLC fingerprint spectrum can be used to distinguish Hypericum Linn. species, the chemical constituents of the plants from Hypericum Linn. were more similar in some degree while the contents of each corresponding component are various.
