Phytochemicals Composition and Anti-bacterial Activity of Vernonia amygdalina

Bacterial infections have become a significant health concern globally, associated with high morbidity and mortality rates. A new study published in Biology, Medicine & Natural Product Chemistry has investigated the phytochemical composition and anti-bacterial activity of the methanol leaves extract of Vernonia amygdalina. The research aimed to evaluate the plant's potential as a local therapy and drug synthesis component. Phytochemicals in the extract were estimated using standard analytical methods, revealing a significant presence of alkaloids, flavonoids, tannins, saponins, steroids, and glycosides.

Key Takeaways:

  • The methanol leaves extract of Vernonia amygdalina contains significant amounts of phytochemicals, including alkaloids (47.44%), flavonoids (16.60%), tannins (4.35%), saponins (12.28%), steroids (0.86%), and glycosides (0.18%).
  • The extract exhibited significant anti-bacterial activity, particularly against certain bacterial strains.
  • The antibacterial activity test was carried out using the agar diffusion method, with minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) determined using the tube dilution method and sub-culturing technique, respectively.
  • Abdulganiyu Mohammed Galadima, a researcher from the Federal University of Technology, led the study.
  • The research findings have potential implications for local therapies and drug synthesis, highlighting the importance of Vernonia amygdalina as a natural resource.
  • The study's results suggest that the extract could be used to combat bacterial infections and mycoses.

Statistics:

  • 47.44% of the extract's phytochemical composition is comprised of alkaloids.
  • 16.60% of the extract's phytochemical composition is comprised of flavonoids.
  • 4.35% of the extract's phytochemical composition is comprised of tannins.
  • 12.28% of the extract's phytochemical composition is comprised of saponins.
  • 0.86% of the extract's phytochemical composition is comprised of steroids.
  • 0.18% of the extract's phytochemical composition is comprised of glycosides.
  • The extract exhibited significant anti-bacterial activity against 8 out of 10 bacterial strains tested.
