Methods: The chemical constituents of the plant were isolated and purified by column chromatography and their structures were elucidated by spectroscopic analysis. Results: Six pounds were isolated and identified as nheneicosanoic acid, βsitosterol, indirubin, adenosine, emodin, Fructopyrano(1→4)glucopyranose. Conclusion: Compounds 1 and 6 are isolated for the first time from the plants of lsatidis Radix.Key words: lsatidis Radix。結(jié)果：從板藍根中分離并鑒定了6個化合物，分別為（1）正二十一烷酸、（2）β–谷甾
