摘　　要：基于正交投影理论和相关色谱方法提出多组分光谱相关色谱 .为克服联用色谱仪器的不等性噪声影响 ,采用目标组分投影前后的光谱夹角余弦判据 ,判断不同的中药色谱指纹图谱的相关组分色谱峰簇 .该方法为中药指纹图谱的数据处理、合理评价以及中药谱效学的基本理论研究提供一种实用的工具 .Multicomponent spectral correlative chromatography is proposed based on orthogonal projection and correlative chromatography. In order to eliminate the influence of heteroscedastic noise derived from hyphenated instruments, the cosine value of between target component spectrum and its projected residue is applied as a criterion to test the correlative component chromatographic clusters of different chemical fingerprints of traditional Chinese medicines (TCMS). This method provides a practical tool for data processing, reasonable evaluation of chemical fingerprints' of TCMs, and the basic theoretical research on relationship between the chemical fingerprints of TCM and its pharmaceutical efficacy.
