ANTIOXIDANT ACTIVITY OF ANTHRAQUINONES ISOLATED FROM LEAVES OF MUEHLENBECKIA HASTULATA (J.E. SM.) JOHNST. (POLYGONACEAE)
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 ofMuehlenbeckia hastulata. The antioxidant activity of these compounds was measured using the DPPH assay; all thr...

| Sumario: | 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 ofMuehlenbeckia hastulata. The antioxidant activity of these compounds was measured using the DPPH assay; all three showed weaker antioxidant activity than gallic acid. |
