Ecdysteroids of Silene repens from Eastern Siberia
- 17 Downloads
The genus Silene L. is represented by ~20 species in Siberia. S. repens Partin (S. amoena L.) is the most common species of the genus in European Russia and Western and Eastern Siberia . Previously, ecdysteroids were found in S. repens introduced to Tomsk Oblast (Russia) and wild plants from Mongolia [2, 3]. The chemical composition of S. repens from natural Siberian populations has not been reported. In continuation of chemical research of Silene species [4, 5], the present communication reports the composition and quantitative contents of ecdysteroids in S. repens specimens growing in the Baikal region.
Plants were collected in the Republic of Buryatia (Bogorodskii Island, Sovetskii District, Russia; 51°47′58.17′′ N, 107°35′17.83′ E; h = 494 m above sea level). The species was determined by Dr. T. A. Aseeva (IGEB, SB, RAS). Raw material was dried in air in the shade to ≤5% moisture and milled to particle size 1–2 mm. Column chromatography (CC) used polyamide, Al2O3, and silica...
