This study aimed to explore and separate the phytochemicals of the whole plant Conyza canadensis, a naturally growing
plant in Iraq, since no phytochemical research was done previously in Iraq. The whole plant of C. canadensis was defatted by
maceration in hexane for 24 hours. The defatted plant materials were extracted using Soxhlet apparatus, the aqueous ethanol
85% as a solvent extraction for 9 hours, and fractionated by petroleum ether, chloroform, ethyl acetate, and n-butanol. The
petroleum ether, chloroform, and ethyl acetate fractions were analyzed by high-performance liquid chromatography (HPLC) for
their steroids, alkaloids, and polyphenolic (phenolic acids and flavonoids) contents. One alkaloid was isolated from chloroform
