Phenolic Compounds And Bioactivity Of Leaves Of Mayodendron igneum Kurz
Abstract
Four apigenin glycosides were isolated from the ethyl acetate extract of the leaves of Mayodendron igneum Fam.Bignoniaceae. They were identified as apigenin 7-O-glucoside; 6-methoxy apigenin-7-O-glucoside; 6-methoxy apigenin-7-O-rhamnoglucoside and 6-hydroxy apigenin-7-O-rhamnoglucoside. In addition an isoflavone glycoside was isolated, and identified as genistin 5,4`-methyl ether. Ethanol (80%) extract of Mayodendron igneum leaves exhibited significant anti-inflammatory and analgesic activities. LD50 determination of the extract indicated the safety of the leaves of the plant.
Keywords: Mayodendron igneum, Bignoniaceae, apigenin glycosides, anti- inflammatory activity.
