  • Structure elucidation using comprehensive spectral analysis, including 2D Nuclear Magnetic Resonance (2D NMR) experiments.

    • Main Results:

    • A new xanthone, 3-(2-hydroxyethoxy)xanthone, was isolated and identified.
    • Three known compounds, 1-hydroxyxanthone, salicylic acid, and the sesquiterpene oplopanone, were also isolated.
    • The structures of all isolated compounds were confirmed through detailed spectral data interpretation.

    Conclusions:

    • The phytochemical investigation successfully identified a new xanthone and three known compounds from Hedychium gardnerianum rhizomes.
    • The findings expand the knowledge of the chemical diversity present in this plant species.
    • The isolated compounds may warrant further investigation for their biological activities.
