Abstract

From the methanolic extract of the flowers of A. napellus spp. tauricum four new flavonol glycosides: quercetin 3-O-(6-trans-caffeoyl)-beta-glucopyranosyl-(1-->2)-beta-glucopyranoside-7- O-alpha-rhamnopyranoside (1), kaempferol 3-O-(6-trans-caffeoyl)-beta-glucopyranosyl-(1-->2)-beta- glucopyranoside-7-O-alpha-rhamnopyranoside (2), quercetin 3-O-(6-trans-p-coumaroyl)-beta-glucopyranosyl-(1-->2)-beta- glucopyranoside-7-O-alpha-rhamnopyranoside (3), and kaempferol 3-O-(6-trans-p-coumaroyl)-beta-glucopyranosyl-(1-->2)-beta- glucopyranoside-7-O-alpha-rhamnopyranoside (4), together with the known beta-3,4-dihydroxyphenethyl beta-glucopyranoside were isolated. The structural elucidation of all compounds was deduced on the basis of 1H- and 13C-NMR spectral data, including those derived from 2D-NMR, as well as on HPLC-MS results.

摘要

从阿尔泰银莲花（Anemone napellus spp. tauricum）花朵的甲醇提取物中分离得到了4种新的黄酮醇苷：槲皮素3 - O -（6 - 反式 - 咖啡酰基）-β - 吡喃葡萄糖基 -（1→2）-β - 吡喃葡萄糖苷 - 7 - O -α - 鼠李吡喃糖苷（1）、山奈酚3 - O -（6 - 反式 - 咖啡酰基）-β - 吡喃葡萄糖基 -（1→2）-β - 吡喃葡萄糖苷 - 7 - O -α - 鼠李吡喃糖苷（2）、槲皮素3 - O -（6 - 反式 - 对香豆酰基）-β - 吡喃葡萄糖基 -（1→2）-β - 吡喃葡萄糖苷 - 7 - O -α - 鼠李吡喃糖苷（3）和山奈酚3 - O -（6 - 反式 - 对香豆酰基）-β - 吡喃葡萄糖基 -（1→2）-β - 吡喃葡萄糖苷 - 7 - O -α - 鼠李吡喃糖苷（4），以及已知的β - 3,4 - 二羟基苯乙基β - 吡喃葡萄糖苷。所有化合物的结构解析是基于1H - 和13C - NMR光谱数据（包括来自二维NMR的数据）以及HPLC - MS结果推导得出的。
