    Summary

    Six triterpenoids from Licania heteromorpha showed antimicrobial activity against Gram-positive bacteria and yeasts. These compounds, including alphitolic acid derivatives, were ineffective against Gram-negative organisms in vitro.

    Area of Science:

    • Natural Product Chemistry
    • Pharmacology
    • Microbiology

    Background:

    • Licania heteromorpha Bentham var. heteromorpha is a plant species known for its potential bioactive compounds.
    • Triterpenoids are a diverse class of natural products with a wide range of biological activities.
    • Investigating the antimicrobial properties of plant-derived compounds is crucial for discovering new therapeutic agents.

    Discussion:

    • Evaluation of in vitro antimicrobial activity against clinically isolated microorganisms using a microdilution method.
    • Differential activity observed: compounds 2, 3, 5, and 6 demonstrated efficacy against Gram-positive bacteria and yeasts.
    • Lack of activity against Gram-negative organisms suggests specific mechanisms or structural requirements for antibacterial action.

    Key Insights:
