A new kaurane type diterpene lactone, neotripterifordin (1), has been isolated from the roots of Tripterygium wilfordii. The structure of 1 was elucidated by spectroscopic methods, which included the concerted application of a number of 2-D NMR techniques including 1H-1H COSY, phase-sensitive NOESY, HETCOR, and long-range HETCOR. Compound 1 showed potent anti-HIV replication activity in H9 lymphocyte cells with an EC50 of 25 nM and TI of 125.
