Phytochemicals are chemical compounds often referred to as secondary metabolites. Thirty three
bioactive phytochemical compounds were identified in the methanolic extract of Citrullus colocynthis.
The identification of phytochemical compounds is based on the peak area, retention time molecular
weight and molecular formula. Gas chromatography-mass spectrometry (GC-MS) analysis of C.
colocynthis revealed the existence of the methyl 6-oxoheptanoate, hexanoic acid, 2-isopropyl-2-methyl-
5-oxo-, methyl ester, dodecanoic acid, 3-hydroxy, benzofuran,2,3-dihydro, 1,1-Cyclopropanedimethanol,

bioactive compounds of C. colocynthis was assayed for in vitro antibacterial activity against Proteus
mirabilis, Escherichia coli, Pseudomonas aerogenosa, P. mirabilis, Staphylococcus aureus and
Klebsiella pneumonia by using the diffusion method in agar. The zone of inhibition was compared with
different standard antibiotics. The diameters of inhibition zones ranged from 4.91±0.260 to 1.03±0.200
mm for all treatments.
