Objective: To establish UV-VIS spectrum or TLC of Dan'an mixtures. Methods: Shimadzu ultraviolent-visible spectrometer and thin layer chromatography were used. Result: Dan'an mixtures had characteristic absordance at the wavelength of 199nmã€278nm and 961nm. The extract of Dan'an mixtures in different way had characteristic spot under natural .. The access to the whole abstract and the presentation file is available to FIP members and to congress participants of that specific congress.
