| In this paper, Powder Micro-image Identification and three modern parsing techniques (Fourier transformation infrared spectrometry, X-ray fluorescence and Powder X-ray diffraction) has carried on the comparison, analysis and research to spaceflight mutagenesis breeding traditional Chinese medicine's whole intrinsic quality characteristic.First, the spaceflight mutagenesis breeding Radix Isatidis and Saposhnikovia divaricata which have advantages on appearance traits such as grow well and strong, were identified and comparative analyzed by using Powder Micro-image Identification. The results showed that the micro-structure of them were different from the ground groups (the ground Radix Isatidis and ground Saposhnikovia divaricata), which indicating the genes of Radix Isatidis and Saposhnikovia divaricata seeds have been effected by the space environment when they were carried into space.Second, the FTIR spectra and the corresponding second derivative FTIR spectra of Radix Isatidis samples (both space group and ground group) were analyzed and researched. It showed that multi-index active ingredients have increased in the space group. FTIR was suitable for analyzing the whole components of the spaceflight mutagenesis breeding traditional Chinese medicine which has large variation extent and quick stability of traits.Finally, crystal material and a variety of elements of the two groups were determined and analyzed. From the XRF spectra, it can conclude that the kinds of elements contained in the two groups were almost the same, but the percentages of those elements were obviously different. It can conclude that the content of crystal material of the two samples was both low, and the space group has less from PXRD spectra.It can conclude that the multi-index active ingredients of space Radix Isatidis have optimized by the analysis,research and characterization of the medicinal herbs from the four dimensions such as powder microstructure, molecule, multi-element and crystal material. |
