Similarity Analysis of FTIR of Lindera aggregata
摘要
Abstract
Objective:To establish Fourier trans form infrared spectrum of Lindera aggregata. Methods:Using two new in-dexes,including common peak ratio and variant peak ratio,were applied,and their values were calculated by means of the sequential analysis for 11 kinds of samples of Lindera aggregata from different cultural areas,in which each sample′s IR fingerprint spectra were set up and the common peak ratio and variant peak ratio sequences were arranged in the order of size in comparison with other samples. Results:It can be seen that Lindera aggregata samples from Ganzhou,Zhejiang, and Fujian could be successfully revealed directly by the common peak ratio and variant peak ratio sequences. Considering the spectral range of 400~4 000 cm-1 ,the common peak ratio of the spectra more than 90%. Conclusion:The fingerprint characters of IR can not only identify the main chemical constituents in medicinal materials,but also compare the compo-nents differences among the similar samples. The analytical method is an rapid,effective,fast and advanced to evaluate the production area for pharmaceutical market.关键词
