BIFLAVONOIDS FROM FLOWERS OF BUTEA MONOSPERMA (LAM.) TAUB.

[摘要]：A new aurone glucoside (1) and three new biflavonoids (12 - 14), together with fourteen known compounds, were isolated from the flowers of Butea monosperma (Lam.) Taub. The structures of the new compounds were established by ID, 2D NMR, MS and CD analyses. The isolated compounds were evaluated for their influenza A neuraminidase inhibitory activity and DPPH free-radical scavenging activity.
