Abstract:
Objective To compare the content of organic acid in Folium Isatidis from differernt Habitats. Methods According to ultraviolet absorption atlases characteristics of the three main organic acid in Folium Isatidis, DSA UV-2401 was used to determinate the acidcontent of Folium Isatidis from differernt Habitats, and carried on to inspect the methodology. Results The difference of the acidcontent of Folium Isatidis from differernt Habitats is notable. Conclusion The method is simple, accurate and duplicated good, and can be used as quantitative analysis method of organic acid in Folium Isatidis.[著者文摘]
