GC-MS analysis and antibacterial activities of some plants belonging to the genus Euphorbia on selected bacterial isolates

Plant extracts have always been used as an alternative source of antimicrobial compounds.

Zusammenfassung:Plant extracts have always been used as an alternative source of antimicrobial compounds. The recent spread of multi-drug-resistant bacteria and their increased treatment costs necessitated the study of alternative, cheap sources. The family Euphorbiaceae has over 300 genera and is widely used in traditional medicine. , , and were selected to study the antibacterial activity of the methanolic extract against 13 Gram-positive strains (including methicillin-resistant ) and 2 Gram-negative isolates, and , by the Kirby Bauer Disc diffusion test. Paper discs with different concentrations of the extracts (100, 50, and 25 µg mL ) were prepared, along with the methanol control and standard antibiotic control. A gas chromatography-mass spectrometry (GC/MS) analysis was done to study the phytochemical components present in the plant methanolic extracts. A total of 50 different phytochemical compounds with antibacterial activity were detected by GC/MS analysis of the plants. Twenty-five compounds were detected in , 24 in , and 21 in . Out of 37 compounds found in and , 12 (32.43%) were common to both. Eleven (22%) compounds were unique to , while 9 (18%) compounds were unique to , and 13 (26%) compounds were unique to . showed the best antibacterial activity against MRSA and Gram-negative bacteria. It also showed higher unique compounds with antibacterial activity (26%), followed by (11, 22%). This is the first GC/MS analysis and antimicrobial activity report of and
