Along with four known terpenoids (1-4), eight new dinorditerpenes (5-12) were isolated and identified from the roots of Flueggea virosa. The absolute configurations of 4-6 were determined by the Mosher's method, and that of 5 was confirmed by single-crystal X-ray diffraction analysis. Using the hepatitis C virus cell culture infection system, compounds 1, 3, 11, and 12 exhibited significant anti-HCV activity with EC50 values of 5.6, 5.0, 7.5, and 6.6 μM, respectively. Compounds 11 and 12 were nontoxic toward the tested Huh7.5 cell lines.
