ZUSAMMENFASSUNG

Two new abietane diterpene glycosides, wilfordosides A (1) and B (2), were isolated from the roots of Tripterygium wilfordii. The structures of compounds 1 and 2 were established using spectroscopic methods including extensive 1D and 2D NMR analysis, in combination with chemical reactions.
