中药材川芎道地性的HPLC指纹图谱主成分分析研究
首发时间:2006-06-26
摘要:目的:应用HPLC指纹图谱研究川芎药材道地性化学特征。方法:建立川芎HPLC指纹图谱,对38个不同类群样本进行指纹图谱分析,采用相似度评价、主成分分析等化学计量学方法进行评价,并对道地川芎、道地川芎副产物及栽培变种(江西抚芎)进行了比较。结果:认为川芎道地性与特征色谱指纹图谱所表达的化学成分含量信息相关。结论:道地药材指纹图谱对于研究药材道地性特征具有积极意义。

Study On The Genuine Characteristics Of Rhizoma Chuanxiong Based On HPLC Fingerprint and Principal Component Analysis
Abstract: OBJECTIVE:To study the genuine characteristics of Rhizoma Chuanxiong by the HPLC fingerprint. METHODS: Established the fingerprint of Rhizoma Chuanxiong by HPLC. Analysed the fingerprints of 38 samples by stechiometry such as similarity evaluation and component analysis. Compared the genuine Rhizoma Chuanxiong with its outgrowth and cultivated variety(Fuxiong of JiangXi). RESULTS:There is a tight correlation between the genuine characteristics of Rhizoma Chuanxiong and the quantity of its secondary metabolism expressed by the fingerprint. CONCLUSION:The method of fingerprint is available to study the genuine characteristics of genuine Chinese medicine materials
Keywords: Rhizoma Chuanxiong;genuine characteristics; fingerprint;
