    Area of Science:

    • Phytochemistry
    • Natural Products Chemistry
    • Plant Sciences

    Background:

    • Phytoecdysones are plant-derived steroids with diverse biological activities.
    • Diplazium donianum is a fern species with potential for novel compound discovery.

    Purpose of the Study:

    • To isolate and identify phytoecdysones from Diplazium donianum.
    • To characterize the chemical constituents of this fern species.

    Main Methods:

    • Phytochemical analysis of Diplazium donianum extract.
    • Isolation and purification of specific compounds using chromatographic techniques.
    • Spectroscopic methods for structural elucidation.

    Main Results:

    • Makisterone A, makisterone D, and an unidentified stereoisomer of makisterone B were successfully isolated.
    • Two additional, as yet unidentified, phytoecdysones were detected in the plant material.

    Conclusions:

    • Diplazium donianum is a source of various phytoecdysones, including known and novel compounds.
    • Further investigation is warranted to fully characterize the unidentified phytoecdysones and assess their biological significance.
