Three new natural ecdysteroids viz. 22‐dehydro‐20‐deoxy‐ajugasterone C (1), 1‐hydroxy‐22‐deoxy‐20,21‐didehydro‐ecdysone (2) and 22‐deoxy‐20,21‐didehydro‐ecdysone (3) were isolated from the methanol extract of the roots of Serratula wolffii . The structures of compounds 1–3 were established by various spectroscopic techniques, including one‐ and two‐dimensional NMR, circular dichroism and mass spectroscopic methods.
