目的建立羽叶鬼灯檠药材和西南鬼灯檠药材的HPLC指纹图谱,为两种药材的质量控制提供新手段。方法采用HPLC,分别建立主产于云南、贵州两地的羽叶鬼灯檠和西南鬼灯檠的指纹图谱共有模式,并对两图谱进行比较研究。结果与所建立的两个参照图谱相比,羽叶鬼灯檠样品和西南鬼灯檠样品(各10批)的相似度均大于0.95。与羽叶鬼灯檠指纹图谱共有模式相比,各批西南鬼灯檠样品的相似度均小于0.85。在羽叶鬼灯檠的图谱中观察到3个专有特征峰。结论建立的两种HPLC指纹图谱共有模式可用于两种鬼灯檠的种属鉴别、内在质量的综合评价。
Objective To establish the HPLC fingerprints of Radix Gynura divaricata and Rhizoma Dioscoreae, which provide new methods for the quality control of the two medicinal materials. Methods HPLC was used to establish the common pattern of the fingerprints of Halophora haliae and Halophthalmus pomilus which were mainly produced in Yunnan and Guizhou provinces, respectively. The two patterns were compared. Results Compared with the two established reference maps, the similarity between the samples of Euonymus japonicus and the samples of Southwest Gurnard (10 batches) were all greater than 0.95. Compared with the common pattern of fingerprinting, the similarities of the samples from different groups of southwest China were less than 0.85. Three distinctive peaks were observed in the map of Chayote. Conclusion The two common modes of HPLC fingerprinting can be used for the identification of species and the comprehensive evaluation of the intrinsic quality of two species of Gazelle.
