  • Structure elucidation using comprehensive spectral data (e.g., NMR, MS).

    • Main Results:

    • Two new acetogenins, designated gardnerilins A and B, were successfully isolated.
    • Both compounds are C35 acetogenins.
    • The structures revealed the presence of non-tetrahydrofuran rings, a notable structural feature.

    Conclusions:

    • Gardnerilins A and B represent novel additions to the known acetogenin family.
    • The structural characterization provides valuable data on acetogenin diversity.
    • Further studies may explore the biological activities of these new compounds.
