A new anthraquinone, named 1,3-dihydroxy-2-methylene-(1′-isopentyloxy)-6-methoxymethyl-8-(6′′,7′′,8′′- trihydroxyphenylketonyl)-9,10-anthraquinone (1), and nine known anthraquinone derivatives (2–10), were isolated from Cucumis bisexualis for the first time. Compounds 1–10 were evaluated for their hepatoprotective activity in human L-O2 cells compared with the positive control bifendatatum. Among them, compounds 1, 3, and 8 exhibited moderate hepatoprotective activity in the proliferation of L-O2 cells.
