  2-Phenoxychromones and a structurally related flavone from leaves ofRosa rugosa

  摘要：

  Two phenoxychromones were identified in leaves of Rosa rugosa: 6-demethoxy-4'-O-methylcapillarisin and 6-demethoxycapillarisin. Apigenin was also found in the leaves. This is the first report of phenoxychromones outside the Compositae.
