From the 1-BuOH-soluble fraction of a MeOH extract of the leaves of Schoepfia jasminodora collected from Okinawa Island, two new galloyl esters and 15 known compounds were isolated. The structures of the new compounds were elucidated by spectroscopic anal

, p. 156 - 162 (2018)
Ten new flavone 8-C-glucosides, trollichinensides A–J, with the substitution of various acyls at C-2″ C-3″ or C-6″ of the glucose moiety, together with thirteen known ones were isolated from the flowers of Trollius chinensis. Spectroscopic analyses including NMR and HRESIMS resulted in the establishment of the structures of these constituents and electronic circular dichroism (ECD) experiment was employed for the determination of the absolute configuration of the glucose residue in these molecules.
C-Glycosyl Flavones from Two Eastern Siberian Species of Silene

, p. 642 - 647 (2019/08/08)
Flavonoids from Silene aprica Turcz. and S. samojedorum (Sambuk) Oxelman (Caryophyllaceae) growing in Baikal region were studied for the first time. A total of 14 compounds including three new compounds 1–3 were isolated. Their structures were established using UV, IR, and NMR spectroscopy and mass spectrometry. Apigenin-6-C-(2″-O-α-L-arabinopyranosyl-6″-O-acetyl)-β-D-glucopyranoside (sileneside A, 1) and apigenin-6-C-(2″-O-β-D-glucopyranosyl-6″-O-acetyl)-β-D-glucopyranoside (sileneside B, 2) were observed in S. aprica; 1 and luteolin-6-C-(2″-O-α-L-arabinopyranosyl-6″-O-acetyl)-β-D-glucopyranoside (sileneside C, 3), in S. samojedorum.
