【Abstract】:Objective: To establish a quality standard for Pogostemonis Folium. Method: We use Patchouli Alcohol as a reference substance to identify Pogostemonis Folium by TLC and to determine the content by GC. We use HP - 5 capillary column, FID detector and temperature programmed. Results: The method of TLC is Characteristic and method of content determination is simple and accurate. Patchouli Alcohol shows a good linear relationship within the range of ~ . The regression equation for Y = x - , R2 = (n = 7) and the average recovery is %,RSD=%(n=6).Conclusion: Methods we used are simple and accurate and showed reliable results. These methods can be used for the study of quality standard of Pogostemonis Folium。
