|
Alcoholic extract of Spathodea campanulata P. aerial parts, and two of the isolated fractions from celite column showed strong antioxidant activity (92, 94 & 89% RSA, Radical Scavenging Activity). Phytochemical investigationof chloroform/EtOAc faction of this column led to the isolation of phenolic acids, caffiec acid (1), and ferulic acid (2), fraction EtOAc/MeOH on further fractionation afforded 3 Flavonoids, kampferol 3-O-glucoside (3), quercetin 3-methyl ether (4) and 8-methoxy kampferol 3-O-glucoside (5). The isolated constituents were identified by co chromatography with authentic samples, TLC, PC., UV, MS and 1H-NMR . Also the lipoidal matter of the plant was studied. The unsaponifiable matter was found to be mixture of hydrocarbons from (C14-C28) , cholesterol, campasterol, stigmasterol, and α-amyrin . Fatty acid methyl esters were found to contain 12 fatty acids. The fatty acids containing C18 farmed ca.65% of the total mixture.
