Abstract A phytochemical investigation of Saussurea medusa Maxim. led to the isolation of eleven compounds, including neoechinulin A (1), 8-hydroxypinoresinol (2), caruilignan D (3), 7(S)-hydroxyarctigenin (4), pinoresinol (5), arctigenin (6), arctii (7), epipinoresinol (8), loliolide (9), apigenin (10), and luteolin (11). Their structures were elucidated by spectroscopic methods and comparison with previously reported spectral data. Among them, compounds 1 and 2 were firstly obtained from this species, compounds 3 and 4 were isolated from the genus Saussurea for the first time. Furthermore, the chemotaxonomic significance of these compounds was discussed in details.
