摘要(Abstract):

目的:本研究提出了一种适用于复方中成药鉴别及质量控制的理论方法——双指标信息显著相似序列聚类分析。方法:根据作者等建立的共有峰率和变异峰率双指标序列分析法,构建了双指标信息方程,将共有遗传信息和变异信息综合成单一信息量,综合刻画生物样品的性质。确定双指标信息显著相似序列并用于聚类分析。结果:将该法应用于组成极其相似的桂附地黄丸和金匮肾气丸无水乙醇提取物红外指纹图谱分析,可以精细准确地将2种复方中成药分类。结论:本研究建立的双指标信息显著相似序列聚类分析法,是一种优良的适用于生物复杂体系的模式识别方法。
Objective: To establish,a novel method,Dual index information markedly similar sequence clustering analysis to identifiy and control the quality of formula Chinese patent medicine.Method: Based on common and variation peak ratio dual index sequence analysis proposed by authors,a new equation was built up,in which the common inherited and variant information could be integrated into unique information represent.It described the properties of biological samples simply and synthetically.The dual index information markedly similar sequence were determined and used to cluster samples.Result: The novel approach was applied for pattern recognition of IR fingerprint spectra of components of Guifu dihuang and Jingui shenqi pills,composed of extremely similar components extracted with ethanol,the two pills could be classified accurately and distinctly.Conclusion: The dual index information markedly similar sequence clustering method is an excellent one-fit pattern recognition one fit to analyze biologically complex samples.
