[Application of FTIR array of correlation coefficient to the identification of Salvia miltiorrhizae Bge].
Based on the fingerprint infrared spectrum database, array of correlation coefficient has been first applied to identify traditional Chinese medicine slviae miltiorrhizae Bge. from different producing areas and growing environments. The result showed that the setting of high correlation coefficient in particular ranges of spectrum could differentiate the producing area of Slviae, while the setting of low correlation coefficient threshold of R5 to R7 ranges could identify wild or cultivated samples. This approach seems to be not only a simple but also an accurate method for identifying the character of different Slviae.
