Biological Activities
Nasturtium microphyllum has demonstrated significant antibacterial activity according to recent in vitro research. Scientists evaluated the aqueous extracts of this medicinal plant against both Gram-positive and Gram-negative bacteria, specifically targeting Staphylococcus aureus and Escherichia coli. The study utilized radial diffusion assays to confirm that the plant possesses satisfactory inhibitory effects. Furthermore, the research highlighted that the extracts are non-toxic, showing no significant haemolytic activity at their minimum inhibitory concentrations. These promising results suggest that the species holds substantial potential for future applications in drug discovery.
Compounds
Conditions
Nasturtium microphyllum demonstrates effective antibacterial activity against both Gram-positive and Gram-negative bacteria. Specifically, the aqueous extracts of this plant show satisfactory results in treating Staphylococcus aureus, which is a Gram-positive bacterium. It also proves successful in combating Escherichia coli, representing a Gram-negative bacterial target. The minimum inhibitory concentration required for these antibacterial effects was found to be less than 750 µg/mL. These findings highlight the plant's dual capability to suppress both major classes of bacteria.
Preparations
Nasturtium microphyllum is prepared as aqueous extracts to facilitate scientific evaluation in an in vitro study. These specific liquid preparations are utilized to determine the plant's antibacterial activities against both Gram-positive and Gram-negative bacteria. By using aqueous extracts, researchers can measure the minimum inhibitory concentration required to suppress bacterial growth. This preparation method also allows for the assessment of non-haemolytic effects on human red blood cells to ensure safety. Consequently, the aqueous extracts of Nasturtium microphyllum serve as a critical component in identifying its potential for future drug discovery.
