The study aimed to determine the bioactive components and antibacterial activities of cold methanolic extract leaves (CMMEL) of Artemisia absinthium L. CMMEL was tested for phytochemicals, GC-MS analyses was performed to identify the bioactive components, and anti-bacterial properties. The phytochemical analysis of CMMEL revealed the presence of carbohydrates, steroids, saponins, and amino acids. GC-MS analysis of CMMEL of A. absinthium L. revealed several unique bioactive compounds, including margaspidin, stigmasterol, octadecanoic acid, hexadecanoic, corymbolone, and bicyclo [2.2.1] heptan-2. The antibacterial spectrum of CMMEL can be sequenced as Streptococcus pyogenes (8.83 ± 1.8 mm) > Escherichia coli (7.6 ± 0.6 mm) > Bacillus subtilis (6.6 ± 1.6 mm) > Klebsiella pneumoniae (6.5 ± 0.3 mm) > Pseudomonas aeruginosa (6.1 ± 1.1 mm) > Staphylococcus aureus (5.23 ± 0.8 mm). Although the CMMEL of A. absinthium L. showed the presence of many bioactive compounds but did not substantially inhibit the growth of Gram-positive or Gram-negative bacteria, according to the findings.
