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.

来自两种东西伯利亚的 Silene 物种的 C-糖基黄酮

来自 Silene aprica Turcz 的黄酮类化合物。首次研究了生长在贝加尔湖地区的 S. samojedorum (Sambuk) Oxelman (Caryophyllaceae)。共分离出 14 种化合物，包括 3 种新化合物 1-3。它们的结构是使用紫外、红外、核磁共振光谱和质谱确定的。Apigenin-6-C-(2″-O-α-L-arabinopyranosyl-6″-O-acetyl)-β-D-glucopyranoside (sileneside A, 1) 和 apigenin-6-C-(2″-O-在 S. aprica 中观察到 β-D-吡喃葡萄糖基-6″-O-乙酰基)-β-D-吡喃葡萄糖苷 (sileneside B, 2)；1 和木犀草素-6-C-(2″-O-α-L-arabinopyranosyl-6″-O-乙酰基)-β-D-吡喃葡萄糖苷 (sileneside C, 3)，在 S. samojedorum 中。
