| description | ABSTRACT
It has been separated a flavonol 3,5,7,4'-tetrahydroxy flavone (kaemferol) from the methanol extract partitioned by ethyl acetate of the leaves of the fern Chingia sakayensis (Zeiller) Holtt. This was obtained as yellow crystals with m.p. 271-273°C. Characterization of its molecular structure was carried out by spectroscopic methods (UV, IR, 1H-NMR, HMQC, HMBC, 13C-NMR and FABMS). Kaemferol indicated the DPPH free radical scavenger activity in TLC autography.
Keywords: Chingia sakayensis (Zeiller) Holtt, flavone, kaemferol, DPPH free radical scavenger activity |
