  • Structure determination via comprehensive spectroscopic analysis (NMR, MS).

    • Main Results:

    • Isolation and identification of two new natural ecdysteroids: 11alpha-hydroxyprogesterone (1) and herkesterone (2).
    • 11alpha-hydroxyprogesterone is the first reported 11-hydroxylated C21 ecdysteroid.
    • Herkesterone is characterized by a novel 7,9(11)-dien-6-one chromophore.

    Conclusions:

    • Serratula wolffii harbors novel ecdysteroid structures.
    • The discovery expands the known chemical diversity of ecdysteroids.
    • Further research may explore the biological activities of these new compounds.
