摘要
目的:采用HPLC建立两面针药材特征指纹图的分析方法,为市场上流通的两面针药材提供质控参考。方法:建立两面针HPLC特征指纹图谱方法,并结合相似度评价及系统聚类分析方法对市场上购买的25批样品药材进行初步的鉴别分析,鉴定两面针药材真伪及品质优劣。结果:在25批市场抽样的药材中,仅有8批被鉴定为质量较好的正品,有7批被鉴定为次品,7批被鉴定为两面针常见伪品飞龙掌血,3批被鉴定为伪品。结论:本法准确、方便、可靠,可用于两面针药材的鉴别和质量控制。
Objective： To establish the characteristic fingerprint of Zanthoxylum nitidum by HPLC, and to provide a reference for the quality control of Z. nitidum in the market. Method： The established HPLC characteristic fingerprint of Z. nitidum, combined with similarity evaluation and system clustering analysis method, were applied to distinguish 25 batches of samples purchased from market preliminarily, to identify the authenticity and quality of Z. nitidum ingredients. Result： In the 25 batches of samples purchased from market, only 8 batches were identified as genuine with good quality, 7 batches were identified as defective, 7 batches were identified as common counterfeit Toddalia asiatica, and 3 batches were identified as counterfeit. Conclusion： This method is accurate, convenient and reliable. It can be used for identification and quality control of Z. nitidum ingredients.
