【 摘 要 】

Three anthraquinones, the well known emodin (3) and physcion (6) and the new anthraquinone glycoside emodin-8־β־D-idopyranoside (7) were isolated from leaves of Muehlenbeckia hastulata. The antioxidant activity of these compounds was measured using the DPPH assay; all three showed weaker antioxidant activity than gallic acid.
