Novel Ecdysteroids from Serratula wolffii

الملخص EN

Two new and one known ecdysteroids were identified in the methanolic extract of the roots of Serratula wolffii.

The new compounds isolated were ponasterone A-22-apioside (1) and 3-epi-shidasterone (3), together with the known 3-epi-22-deoxy-20-hydroxyecdysone (2).

The structures of compounds 1–3 were determined by extensive spectroscopic techniques, including one- and two-dimensional NMR methods.
