  • Abstract:

    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 199nm、278nm and 961nm. The extract of Dan'an mixtures in different way had characteristic spot under natural ..
