From the dried roots of Euphorbia nematocypha, eight new diterpenoids, with ent‐atisane (i.e., 1 – 5 ) and isopimarane (i.e., 6 – 8 ) type skeletons, together with five known compounds, were isolated. The structures of these new compounds were elucidated by spectroscopic data. Compounds 1 – 8 were evaluated for their cytotoxicity against a small panel of human cancer cell lines. 相似文献
