摘　　要：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（l） 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）.Two new natural methoxyflavonoids and two known methoxyflavonoids were isolated from the ethanol fraction of the leaves of Murraya paniculata（L.） Jack.
