Two new natural methoxyflavonoids from leaves of Murraya paniculata(L.) Jack

Abstract

Two new natural methoxyflavonoids and two known methoxyflavonoids were isolated from the ethanol fraction of the leaves of Murraya paniculata (L.) Jack. The two new natural methoxyflavonoids were elucidated as 2′-hydroxy-3,4,5,3′,4′,6′-hexamethoxychalcone(1) and 6,7,8,3′,4′-pentamethoxyflavanone(2) on the basis of ¹³C NMR and mass spectra. The two known methoxyflavonoids were identified as 3′-hydroxy-5,7,4′-trimethoxyflavone(3) and 2′-hydroxy-3, 4, 4′, 6′-tetramethoxychalcone(4).
