Chloromolaena odorata was screened for its phytochemical properties and pharmacological activities. Phytochemical screening of C. odorata indicates the presence of terpenoid, flavonoid and alkaloid. GCMS analysis of the leaf extract of C. odorata shows four major compounds which are cyclohexane, germacrene, hexadecoic acid and caryophyllene. While, HPLC analysis has identify five peaks; quercetin-4 methyl ether, aromadendrin-4’-methyl ether, taxifolin-7-methyl ether, taxifolin-4’-methyl ether and quercetin-7-methyl ether, kaempferol-4’-methyl ether and eridicytol-7, 4’-dimehyl ether, quercetin-7,4’-dimethyl ether. By using the column chromatography, three compounds were isolated; 5,7-dihydroxy-2-(4-methoxyphenyl)chromen-4-one; 3,5-dihydroxy-2-(3-hydroxy-4-methoxy-phenyl)-7-methoxy-chromen-4-one and of 2-(3,4-dimethoxyphenyl)-3,5-dihydroxy-7-methoxy-chromen-4-one.
