The aim of the study is to screen the whole plant extract of Suaeda monoica for its phytochemicals, determine its antibacterial and anti-cancer activities by SRB (sulforhodamine B) assay.



The powdered form of Suaeda monoica with different solvents (ethanol, methanol, acetone, diethyl ether) was used to screen its phytochemicals. MIC (minimum inhibitory concentration) and MBC (Minimum Bactericidal Concentration) were performed using microdilution methods. Based on the results of MIC, the lowest concentration of antibacterial agent was then sub-cultured on agar plates for MBC values. Zone of inhibition was determined using agar well diffusion method. The percentage of cell-growth inhibition for breast cancer cell line (MDAMB-32) was studied using SRB assay.



The analysis revealed the presence of varied classes of phytochemicals except for acidic compounds with ethanol extract showing maximum compounds.All the extracts showed effective antibacterial activity against tested pathogens with MIC, MBC values ranging from (0.0156 to 0.625 mg/ml) and (2.5 to 10 mg/ml) respectively. A significant zone of inhibition was observed with diethyl ether extract against Staphylococcus epidermis. The lowest concentration that showed 50% cell growth inhibition against MDAMB-32 was that of diethyl ether extract (38.83 μg/ml).



The present study depicts Suaeda monoica as a natural source of bioactive compounds with significant antibacterial and anti-cancer activities. Further studies concerning the separation and isolation of the compounds are required.
