New C,O-Glycosylflavones from Six Species of Silene

An investigation of six species of Silene (Caryophyllaceae) cultivated in Baikal District isolated 22 flavonoids, including new C,O-glycosylflavones 1–5. The structures of 1–5 were established using UV and NMR spectroscopy and mass spectrometry as genkwanin 6-C-(2′′-O-β-D-glucopyranosyl)-β-D-glycopyranoside-4′-O-β-D-glucopyranoside (sileneside H, 1) and genkwanin 6-C-[2′′-O-(2′′′-O-caffeyl)-β-D-glucopyranosyl]-β-D-glucopyranoside (sileneside I, 2) from S. badachschanica Ovcz. and S. daghestanica Rupr.; isovitexin 2′′-O-(2′′′-O-acetyl)-β-D-glucopyranoside-6′′-O-β-D-glucopyranoside (sileneside J, 3) from S. dichotoma Ehrh. and S. iberica M. Bieb.; isovitexin 2′′,6′′-di-O-caffeate (sileneside K, 4) from S. turgida M. Bieb. ex Bunge; and schaftoside 2′′-O-caffeate (sileneside L, 5) from S. sibirica Pers. Compounds 2 and 5 possessed antiradical activity.
