aqueous extract. The C.colocynthis leaves underwent chemical and botanical analysis. A phytochemical examination identified the presence of phenols, tannins, alkaloids, flavonoids, proteins, amino acids, cardiac glycosides, saponins, carbohydrates, and phytosteroids. Furthermore, the plant's composition was analyzed using GC-MS techniques. C. colocynthis is known for its antibacterial effects. The researchers investigated how the extract from C.colocynthis leaves interacted with three antibiotics at specific levels: tetracycline (30 mg/ml), chloramphenicol (34 mg/ml), and gentamicin (50 mg/ml). They employed the disc diffusion technique to evaluate the extract effectiveness against Escherichia coli, and Staphylococcus aureus,. The study assessed the extract capacity to inhibit growth compared to standard antibiotics.

centuries to capably treat various ailments, including coughs, colds, and
digestive issues. Renowned for its expectorant, diaphoretic, and antiinflammatory properties, this precious herb has become a cornerstone of
traditional medicine worldwide. In this study, the productivity of the
ethanolic extract was an impressive 33.69%, while the aqueous extract
showcased a still remarkable 14.5%. The pH levels confirmed the
ethanolic extract at 4.02 and the aqueous extract at. 6.61. Phytochemical
screening exposed the existence of beneficial compounds, such as
alkaloids, flavonoids, saponins, phenols, steroids, and terpenes in both
extracts. It is noteworthy that the ethanolic extract exhibited a higher
presence of tannins, which were not found in the aqueous extract. In
contrast, the ethanolic extract did not contain phenols, whereas the
aqueous extract contained a significant amount of these compounds. To
further explore the biological potential of these extracts, this study was
conducted on their activity against E. coli and S. aureus. The findings
revealed that the aqueous extract's astounding inhibition zones, measured
at 19 mm and 17 mm against E. coli and S. aureus, respectively. The
ethanolic extract also exhibited noteworthy results, with inhibition zones
of 16 mm and 18 mm against E. coli and S. aureus correspondingly.
Clearly, Marrubium vulgare L. is a truly remarkable herb with immense
medicinal value.
