摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗建立秦皮及其混淆品的高效液相色谱(high performance liquid chromatography,HPLC)指纹图谱分析方法,为秦皮质量控制提供新依据。
〖HTH〗方法〖HTSS〗〖KG*2〗采用Zorbax SBC18色谱柱(250 mm×4.6 mm,5 μm),流动相为甲醇(A)-0.5‰乙酸水缓冲溶液(B),梯度洗脱,检测波长230 nm。利用中药色谱指纹图谱相似度评价系统,以秦皮甲素为参照峰,分别建立52批、4种秦皮样品与3批混淆品的HPLC指纹图谱。
〖HTH〗结果〖HTSS〗〖KG*2〗52批秦皮得到10个共有峰,可分为3类,其相似度分别在0.8~1.0、0.6~0.8和0.4~0.6之间;4种不同品种秦皮品种内相似度较高,而品种间存在差异;3批混淆品相似度均低于0.47,且共有峰仅有2个,与正品差异巨大。
〖HTH〗结论〖HTSS〗〖KG*2〗建立的HPLC指纹图谱分析方法能简便、快速地区分秦皮正品与混淆品,可用于秦皮的质量控制。

Abstract: [Abstract]〓Objective〖HTSS〗〓To establish the high performance liquid chromatography(HPLC) fingerprint of Cortex Fraxini and its confusable species and to provide a new basis for quality control of Cortex Fraxini.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓The chromatographic separation was carried out on an Agilent Zorbax SBC18 column(250 mm×4.6 mm, 5 μm) with solvent A (methanol) and solvent B(water containing 0.5‰ acetic acid) as the mobile phases in gradient elution. The detection wave length was 230 nm. Using the similarity evaluation system of chromatographic fingerprints of traditional Chinese medicine, taking aesculin as reference peak, the fingerprints of 52 batches, 4 cultivars of Cortex Fraxini samples and 3 batches of confusable species were established respectively.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Ten common peaks were found in 52 batches of Cortex Fraxini, and the 52 batches of samples could be divided into 3 categories, with similarities ranging from 0.8 to 1.0, 0.6 to 0.8 and 0.4 to 0.6, respectively. The similarity within 4 cultivars of Cortex Fraxini was higher, but there were differences among cultivars. The similarity of the 3 batches of confusion species was less than 0.47, and there were only two peaks, which showed great difference compared with the genuine products.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The established HPLC fingerprint method of Cortex Fraxini could distinguish Cortex Fraxini with confusable species, which could be used for the quality control of Cortex Fraxini.
