Researchers isolated amentoflavone, a known biflavone, from the bark of the Indian almond tree (Mangifera indica). This marks the first documented instance of biflavone isolation from this plant source.

Area of Science:

  • Phytochemistry
  • Natural Product Chemistry
  • Plant Sciences

Background:

  • Mangifera indica (Indian almond tree) is a widely utilized plant in traditional medicine.
  • Biflavonoids are a class of natural compounds with diverse biological activities.
  • Previous phytochemical studies have not reported the isolation of biflavones from Mangifera indica bark.

Purpose of the Study:

  • To investigate the phenolic constituents of Mangifera indica bark.
  • To isolate and characterize any novel or known compounds present in the bark extract.
  • To establish the presence of biflavones in Mangifera indica for the first time.

Main Methods:

  • Phenolic extraction from Mangifera indica bark.
  • Isolation of the target compound using chromatographic techniques.

  • Characterization of the isolated compound through spectroscopic methods (e.g., NMR, MS) and chemical analysis.

    • Main Results:

    • A known biflavone, identified as amentoflavone, was successfully isolated from the phenolic extractive.
    • Spectral and chemical data confirmed the identity of amentoflavone.
    • This study provides the first report of amentoflavone isolation from Mangifera indica.

    Conclusions:

    • Amentoflavone is a constituent of Mangifera indica bark.
    • The isolation of amentoflavone contributes to the phytochemical understanding of Mangifera indica.
    • This finding may warrant further investigation into the potential bioactivities of amentoflavone from this source.
