摘要

Fuscatone A (1), liriodenine (2), oxoxylopine (3), (–)-anonaine (4), (–)-asimilobine (5), (–)-xylopine (6), corydaline (7), thalifoline (8), N-trans-feruloyltyramine (9), 3′,4′,5′-trimethoxycinnamic acid (10), ferulic acid (11), isoferulic acid (12), (+)-lariciresinol (13), β-sitostenone (14), stigmastanone (15), santamarin (16), and dihydrosantamarine (17) were isolated from the flowers of Michelia figo (Magnoliaceae). Among them, fuscatone A (1) is a new δ-lactone (3-methoxy-3-methyl-δ-valerolactone). The structures of these compounds were characterized and identified by spectral analyses.
