Saussurea medusa Maxim (S. medusa) is a rare materia medica used by Tibetans in Chinese phytotherapy. The contents of arctigenin in different organs of S. medusa were examined. The samples were analyzed by high-performance liquid chromatography (HPLC). It was found that all samples contained arctigenin at concentrations ranging between 0.016±0.011 mg g-1 (Stem) and 7.329±0.360 mg g-1 (Seed), respectively. The content of arctigenin in seed was significantly higher than in other organs of S. medusa. Compared to distribution of arctigenin in different organs of S. medusa, arctigenin mainly exists in reproductive organs and in vegetative organs with trace of S. medusa.
