RESUMEN
OBJECTIVE: To establish an FTIR method to identify Xanthium sibiricum from different habitats. METHODS: FTIR spectra of Xanthium sibiricum from different habitats were analyzed,and the similarity of different fingerprint spectra and the chemical pattern recognition were calculated and analyzed according to the wave numbers of peaks. RESULTS: Different FTIR spectra of 10 different habitats of Xanthium sibiricum were obtained,and the similarities were all above 0. 96. CONCLUSION: This method can be used for identification on Xanthium sibiricum from different habitats. The results of similarity calculation and chemical pattern recognition further prove the feasibility of this method.

OBJECTIVE: To provide a FT-IR new method to identify different habitats of Solanum lyratum. METHODS: Analyzed FT-IR patterns of Solanum lyratum from different habitats, and the similarity of different fingerprint patterns was calculated and analyzed according to the wave numbers of peaks searched. RESULTS: Obtained the different FT-IR pattern of 5 different habitats of Solanum lyraturn. CONCLUSION: This method can be used for identifications on different habitats of Solanum lyratum. The results of similarity calculation further prove the feasibility of this method.

OBJECTIVE: To provide an X-ray diffraction (XRD) method for identifying different medicinal parts of Solanum lyratum. METHODS: Analyzed X-ray diffraction Fourier patterns of different parts of Solanum lyratum, and the similarity degree of different fingerprint was calculated and analyzed according to the position (2 theta value)of peaks searched. RESULTS: Different X-ray diffraction Fourier patterns of different medicinal parts of Solanum lyratum were obtained. CONCLUSION: This method can be used for identifying different medicinal parts of Solanum lyratum. The results of similarity calculation further proves the feasibility of this method.

OBJECTIVE: To optimize the matrix formulation of cataplasm used to cure infantile diarrhea. METHODS: The optimum proportion of matrix for the preparation technology process of cataplasm was selected by uniform design and SPSS regression analysis. A check-up for adhibition , peeling strength, nonflowing, content of cream was founded. RESULTS: The best matrix's prescription gelatin: CMC-Na: PANA: kaolin: aluminum trichloride: citric acid: PVP K-30: PEG400: trimethylene glycol: tween-80 was 0.25 : 0.1 : 0.2 : 1.5 : 0.4 : 0.6 : 0.8 : 2 : 1 : 0.5. CONCLUSION: The preparation technique of cataplasm is feasible, and its quality is steerable, it is a safe and effective transdermal-drug delivery system.
