Abstract
Ashwagandha (Withania Somnifera L.) plant is a medicinal plant used to treat various ailments in Iraq by herbalists, the pharmacological evaluation of its leaves despite the rich pharmacological potential of its roots was not done, in this re-search, the phytochemicals from the Ashwagandha (Withania Somnifera L.) leaves were extracted by different types solvents (carbon tetrachloride, chloroform, ethanol and water respectively), presence flavonoids, tannins, saponin, steroids in water and ethanol extracts while the saponin and steroids only were present in chloroform and carbon tetrachloride extracts, the water and ethanolic extracts were found to be good inhibitor or good active against Pseudomonas aeruginosa bacteria, and this activity may be belong to polyphenolic compounds such as flavonoids and tunnies com-pounds, and by comparing the GC/MS analysis chromatogram of extracted sample with NIST database entries, identification compounds by peak value of the unknown compound in chromatogram. In chloroform extract among the 16 phytochemicals identified, 1,2,3,5-Cyclohexanetetrol is the most abundant compound present followed by n-Hexadecanoic acid (Palmitic acid), then Acetic acid, 3,5-Dihydroxy-6-methyl-2,3-dihydro-4H-pyran-4-one, 5-Hydrxoy methyl furfural, Caryophyllene oxide, α-Tocopherol-β-D-mannosidic respectively, other compounds revealed are n-Decanoic acid, Formic acid, cis-3-Hexenylpyruvate, 4-Octyl tetradecyl Phthalate ester, etc. In ethanol extract among the 21 phytochemicals identified, O-Butyl hydroxylamine is the most abundant compound present followed by Hexanoic acid ethyl ester, then Oleyl alcohol, trifluoroacetate, Oleic acid, etc
