title: [X-ray diffraction Fourier fingerprint of mineral Chinese medicine Chloriti Lapis].
abstract: The technology of powder X-ray diffraction (XRD) was used for analysis Chloriti Lapis and the XRD Fourier fingerprints were established. The dates were analyzed by fuzzy cluster and fingerprint similarity evaluation software to compare the similarity of samples. XRD fingerprint with 10 common peaks of 14 batches of Chloriti Lapis were established. The average, median coefficients of crystal lattice spacing d (A), peak position 2 theta, relative intensity value I/I0 (%) were all more than 0.95. And similarity( angle cosine value) were all more than 0. 97. There were small number samples differed from others. And obvious differences between the pre-and post-processing samples. This paper shows the powder XRD Fourier fingerprint can be used for appraisal and study of the Chloriti Lapis.
