title: Structure and stereochemistry of novel ecdysteroids from the roots of Serratula wolffii.
abstract: 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.
