Two new acylated flavonol glycosides, 3-O-{[2-O-beta-D-glucopyranosyl]-3-[O-beta-D-glucopyranosyl]-4-[(6-O-p-coumaroyl)-O-beta-D-glucopyranosyl]}-alpha-L-rhamnopyranosyl-kaempferol 7-O-alpha-L-rhamnopyranoside and 3-O-{2-[(6-O-p-coumaroyl)-O-beta-D-glucopyranosyl]-3-[O-beta-D-glucopyranosyl]-4-[(6-O-p-coumaroyl)-O-beta-D-glucopyranosyl]}-alpha-L-rhamnopyranosyl-kaempferol 7-O-alpha-L-rhamnopyranoside, trivially named as brauhenefloroside E (1) and F (2), respectively, were isolated from the fruits of Stocksia brauhica and their structures were elucidated using spectroscopic methods, including 2D NMR experiments.
从 Stocksia brauhica 的果实中分离得到两种新的酰化黄酮醇糖苷:3-O-{[2-O-β-D-吡喃葡萄糖基]-3-[O-β-D-吡喃葡萄糖基]-4-[(6-O-对香豆酰基)-O-β-D-吡喃葡萄糖基]}-α-L-鼠李吡喃糖苷基-山柰酚 7-O-α-L-鼠李吡喃糖苷(1)和 3-O-{2-[(6-O-对香豆酰基)-O-β-D-吡喃葡萄糖基]-3-[O-β-D-吡喃葡萄糖基]-4-[(6-O-对香豆酰基)-O-β-D-吡喃葡萄糖基]}-α-L-鼠李吡喃糖苷基-山柰酚 7-O-α-L-鼠李吡喃糖苷(2),分别命名为 brauhenefloroside E(1)和 F(2)。这些化合物的结构通过光谱学方法,包括 2D NMR 实验进行了阐明。
