Foeniculum vulgare Mill., commonly called fennel, is a medicinal plant belonging to the Umbelliferae (Apiaceae) family, and is used in traditional medicine. Antibacterial peptides were isolated using sodium phosphate citrate buffer and, for extraction, cetyltrimethyl ammonium bromide (CTAB) buffer with pH 6, have been employed and antimicrobial activity tested against four reference strains. The extracted protein was subjected to 3 kDa dialysis and separation was carried out by DEAE-ion exchange chromatography and further proteins were identified by 2D gel electrophoresis. The results of Foeniculum vulgare elutes obtained from DEAE-ion exchange chromatography were tested for antibacterial activity. Elute 3 shows the highest antibacterial activity on Pseudomonas aeruginosa with a diameter of a zone of inhibition of 16 mm and IC50 value 25.02 (mcg/mL). Based on the findings of the wide usage in treatment of various ailments and day-to-day life, Foeniculum vulgare seeds were used in the present research and have shown promising antibacterial effects, which requires further proteomic research to authenticate the role of the anticipated proteins.
