Abstract Three new compounds (1 – 3), including two euphane type triterpenes, 24,24‐dimethoxy‐25,26,27‐trinoreuphan‐3β‐ol (1) and (24S)‐24‐hydroperoxyeupha‐8,25‐dien‐3β‐ol (2), and an ent‐atisine diterpene, ent‐atisane‐3α,16α,17‐triol (3), were isolated from an acetone extract of the stems of Euphorbia antiquorum, together with eight known diterpenes (4 – 11). The structures of compounds (1 – 11) were elucidated using NMR and MS spectroscopic methods. Compound 7 showed moderate activity against HIV‐1 replication in vitro (EC50 = 1.38 μm).
