Abstract A new flavone, 3′-hydroxy-5,6,7,4′,5′-pentamethoxyflavone (1), and three natural products (7, 10, and 14) were isolated from the leaves and twigs of Murraya paniculata (L.) Jack, together with 10 reported polymethoxylated flavonoids. The structure of compound 1 was elucidated on the basis of comprehensive analysis of 1D and 2D NMR and HRMS spectroscopic data. Moreover, the chemotaxonomic significance of these compounds was also discussed.
