| Abstract: | Similarity analysis of FTIR of Lapis Micae Aureum was carried out to find out the relationship between similarity of infrared spectra and the quality of medicine samples,and try to provide a new method for its quality assessment.FTIR was used to analyze Lapis Micae Aureum samples.Then 6 samples with good quality were picked up to establish a reference infrared spectra by their infrared spectra.Correlation coefficient method and the included angle cosine method were used to calculate the similarity between s... |
