Abstract

The study aimed to assess the antimicrobial potential of aqueous and methanolic extracts from Brassica rapa L. leaves. Phytochemical analysis revealed the presence of various compounds including carbohydrates, fats, proteins, vitamins, minerals, electrolytes, sugars, soluble and insoluble fiber, and amino acids. Both extracts were evaluated for antibacterial activity against six microorganisms, including gram-positive and gram-negative bacteria, compared with the standard antibiotic Gentamycin. Methanolic extract exhibited higher antibacterial efficacy against gram-positive bacteria compared to the aqueous extract.

Although specific active components were not isolated, the plant extracts contained potential antibacterial agents such as soluble fiber, minerals, amino acids, isothiocyanate glycosides, and essential oils. Additionally, compounds like 3,3'-diindolylmethane, sulforaphane, selenium, indole-3-carbinol, and vitamins like C, E, A, and K were identified. The methanolic extract, rich in sulfur and nitrogen-containing compounds, showed promising antibacterial activity against gram-positive bacteria.

In conclusion, Brassica rapa L. leaves could serve as a valuable source for developing safe antibacterial agents. The observed spectrum of activity suggests the potential for further exploration in drug development.
