| 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). |
