Thirteen newent-isopimarane-type diterpenoids,1–10and14–16, and seven known diterpenoids,11–13and17–20, were isolated from the roots ofEuphorbia hylonoma.Among these compounds, four pairs of C-12 epimers (1vs2,4vs5,12vs13, and14vs15) were identified. The structures of the new diterpenoids were elucidated using spectroscopic data analyses, electronic circular dichroism, and single-crystal X-ray diffraction data. The phytotoxic effects of compounds1–20on the growth of the roots and shoots ofPoa annuaandFestuca arundinaceaseedlings were evaluated. Among the tested diterpenoids,18was the most active for inhibiting the growth ofP. annuaseedlings, and this compound was as active as glyphosate.
