Introduction

In the realm of natural products, plants have been a treasure trove of bioactive compounds with immense potential for medicinal applications. Among these, the Kanyere Rhino plant (Bridelia glauca blume) has garnered significant attention due to its rich content of flavonoid compounds. This study aims to isolate and identify these flavonoids from the bark of the Kanyere Rhino plant and investigate their antibacterial activity against Staphylococcus aureus and Escherichia coli.

The Significance of Flavonoids in Medicinal Applications

Flavonoids are a class of plant-derived compounds known for their antioxidant, anti-inflammatory, and antibacterial properties. These bioactive molecules have been extensively studied for their potential in developing novel therapeutic agents. The Kanyere Rhino plant, being a rich source of flavonoids, presents an exciting opportunity for researchers to explore its medicinal applications.

Methodology for Isolating Flavonoid Compounds

The isolation of flavonoid compounds from the bark of the Kanyere Rhino plant involved a multi-step process. A total of 2500 grams of plant stems were extracted using methanol solvents, followed by repeated extraction with ethyl acetate to obtain a negative result in the 5% FeCl3 test. The resulting ethyl acetate extract was then dissolved in methanol and extracted with N-hexane until the N-hexane layer became transparent.

Purification and Analysis of Flavonoid Compounds

Further analysis was performed using thin layer chromatography (TLC) to separate the compounds. A deeper separation was achieved using column chromatography with a silica gel and mixture phase of chloroform mixture: methanol in various compositions (90:10; 80:20; 70:30; 60:40) V/V. The fraction 148-174 was purified using a preparative thin layer chromatography with Benzene solvent: Acetone (80:20) V/V, producing a brownish yellow paste weighing 10 mg at an RF value of 0.66.

Characterization of Flavonoid Compounds

The analysis using the UV-Visible spectrophotometer showed the maximum wavelength (λ max) at 275 nm. The FT-IR spectrum indicated the presence of functional groups OH, C = C aromatic, C = O Keton, and C-H, C-O-C, and C-O. Further analysis with the Spectroscopy of Proton Nuclear Magnetic Resonance (1H-NMR) showed the presence of Proton H-2 '& H-6', H-3 '& H-5', as well as proton metox. Based on the results of analysis and interpretation, the isolated compounds were categorized as flavonoids of the flavanone group.

Antibacterial Activity Tests

The antibacterial activity of total flavonoids was tested using the diffusion method for Staphylococcus aureus and Escherichia coli bacteria. The results showed that total flavonoids significantly inhibited the growth of the two bacteria. The minimum concentration value of inhibition (MIC) produced was 100 mg/ml, with a clear zone formed by 9.5 mm for Staphylococcus aureus and 12.15 mm for Escherichia coli.

Conclusion and Future Directions

This study demonstrates the potential of the Kanyere Rhino plant as a source of flavonoid compounds with antibacterial activity. The results of this study open up new avenues for further research on the medicinal applications of this plant. With a deeper understanding of the nature and activity of these compounds, it is expected to lead to the development of novel antibacterial agents and contribute to the advancement of natural product-based medicine.

Recommendations for Future Research

Further isolation and characterization of flavonoid compounds: To identify and isolate more flavonoid compounds from the Kanyere Rhino plant and to characterize their structures and properties.
Investigation of antibacterial activity against other pathogens: To investigate the antibacterial activity of total flavonoids against other pathogens, including Gram-negative bacteria and fungi.

Limitations and Future Directions

This study has several limitations, including the small sample size and the limited number of bacterial strains tested. Future studies should aim to address these limitations by increasing the sample size and testing the antibacterial activity of total flavonoids against a wider range of bacterial strains. Additionally, further research is needed to explore the potential medicinal applications of the Kanyere Rhino plant and to develop novel antibacterial agents based on its flavonoid compounds.
