Immunosuppressive terpenoids from extracts of Tripterygium wilfordii
Tetrahedron 57(2001)8413～8424，-0001，（）：
The dlinically uded extract (TⅡ) of Tripterygium wilfordii Hook f. give 19 new compounds, including five kaurane diterpenes (1-5), one manoyl oxide diterpene (6), and one abietane diterpene (7), three ursene triterpenes (8,9and15), six oleanane triterpenes (10-13,16and19), and three friedelane triterpenes (14, 17and18), as well ad 15 known compounds (20-34). Their structures were elucidated by spectroscopy and X-ray analysis. Based on the screening of isolated compounds and other compounds reported in previous papers [J. Nat. Prod. 62 (1999) 1522; J. Nat. Prod. (2001) in press; Phytochemistry 53 (2000) 805], we identified the main components that are responsible for the therapeutic effect of TⅡ.
