| Abstract: | Objective To determine total tritepenoidic acid in injection Herba Hedyotis Diffusae. Methods Total tritepenoidic acid was determined by vanilin-perchloric acid method and UV spectrophotometry. Results The UV absorbance peak of tritepenoidic acid was at 548nm. The linear ranges of tritepenoidic acid were from 1.56 to 14.06 ug/ mL （r = 0. 999 6）. Tritepenoidic acid could be stable within 90 min. Conclusion The established method is easy and accurate, thus it is applicable for the quality control of injection Herba Hedyotis Diffusae. |
