Chemical constituents from the roots and rhizomes of Silene tatarinowii Regel

Chemical investigation of the root and rhizome of Silene tatarinowii Regel led to the isolation of nine ecdysteroids (1–9) and one sterol (10). All the compounds were determined on the basis of MS and NMR and by comparison with those in the literature. All these compounds were isolated from S. tatarinowii for the first time. Furthermore, compounds 7–10 were isolated from Silene genus for the first time, of which compounds 7 and 8 were isolated from Caryophyllaceae family members for the first time. This is the first study to report the chemical constituents of S. tatarinowii and the chemotaxonomic relationships between Silene and other genera of Caryophyllaceae.
