摘　　要：A new flavonoid, acacetin-7-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucuronopyranoside (1), together with four known flavonoids, apigenin-7-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucuronopyranoside (2), acacetin (3), acacetin-7-O-β-D-glucuronide (4) and genkwanin-5-O-primveroside (5) were isolated from the leaves of Glyphaea brevis. Their structures were elucidated by spectroscopic techniques. The isolated compounds (1 - 5) were tested for their antioxidant activity using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. The tested compounds showed slight negative antioxidant activities against DPPH radicals.A new flavonoid, acacetin-7-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucuronopyranoside (1), together with four known flavonoids, apigenin-7-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucuronopyranoside (2), acacetin (3), acacetin-7-O-β-D-glucuronide (4) and genkwanin-5-O-primveroside (5) were isolated from the leaves of Glyphaea brevis.
