摘要：
Eleven compounds (1–11), including two new compounds (1, 2), were isolated from the antioxidant portion of the alcoholic extract of Urtica fissa flowers. Their chemical structures were elucidated from extensive spectroscopic analysis. The results of activity evaluation indicated that some compounds of phenolic acids (3, 4), flavonoids (7, 9, 10), and lignans (1, 6) possess significant activities of ABTS and DPPH radical scavenging, with EC50 values less than 8 μM.
