Abstract

From the alcoholic extract of the defatted powdered aerial parts of the flowering plant, six flavonoid glycosides have been isolated together with large amounts of sucrose and sodium chloride. Four glycosides were hydrolysed and their aglycones were identified as 3,6,7-trimethoxy-4',5'-dihydroxyflavone (penduletin); kaempferol-6-methyl ether; 5,7-dihydroxy-4'-5'-dimethoxyflavone (diosmetin) and kaempferol-6,7-dimethylether. The other two glycosides were minors and un-identified, but spectroscopic data are given. The sugar parts of the identified four glycosides were, glucosyl, arabinosyl, glucosyl and rhamnosyl respectively as identified by paper chromatography and TLC against authentic carbohydrates.
