Study on Rapid and Nondestructive Analysis of Danshen Formula Particles by FTIR

The authors applied Fourier transform infrared(FTIR) spectra to research the quality control of Danshen formula particles manufacturing process and to analyse formula particles from different pharmaceutical factories.The authors can confirm the sort and relative content of supplementary materials by the characteristic absorption peaks of sugar in the range from 1 160 to 1 000 cm-1.The intensity of absorption peaks becomes stronger when the relative content of supplementary materials is higher.The authors can evaluate the relative content of effective component in danshen formula particles by the characteristic absorption peaks at 1 608 cm-1.The intensity of absorption peaks becomes stronger when the relative content of the effective component is higher.FTIR spectrometry is an effective and fast method not only for the quality control of Danshen formula particles,but also for identifying the manufacturing technics.
