Abstract

From the air-dried powdered leaves of Murraya exotica L. (Rutaceae), six methoxylated flavones were isolated and identified as: 3,5,6,7,8,3`,4`,5`,-octamethoxyflavone; 3,5,6,7,3`,4`,5`,-heptamethoxyflavone; 5,6,7,3`,4`,5`,-hexamethoxyflavone; 5,6,7,3`,4`,-pentamethoxyflavone; 3,5,7,3`,4`,5`,-hexamethoxyflavone and 3,5,7,8,3`,4`,5`,-heptamethoxyflavone.
The identification was based on physical, chemical and spectral studies including ¹H-NMR, ¹³C-NMR and MS analysis.
The antimicrobial and cytotoxic activities of the isolated compounds were studied.
