ISOLATION AND CHARACTERIZATION OF THE FLAVONOID KAEMPFEROL-3-O- (2’’-O-(3-HYDROXY BUTANOYL)-Α-L ARABINOSIDE FROM DATURA INNOXIA FLOWERS

The present study was isolating the new compound Kaempferol-3-O-(2’’-O-(3hydroxy butanoyl)-αL arabinoside from the flowers of Datura innoxia. The extraction and fractionation was carried out using the solvents of ethanol, benzene, petroleum ether, diethyl ether and ethyl acetate. The structure of the isolated compound was investigated by physical and chemical methods. The new compound was characterized by various spectroscopic techniques viz UV, 1H NMR, 13C NMR and MS.
