中华青荚叶的一个新果糖酯(英文)

A New Fructofuranoside from Helwingia chinensis (Cornaceae)

从山茱萸科中华青荚叶(Helwingia chinensis)的乙醇提取物中分离得到一个新果糖酯和十个已知化合物。通过现代波谱技术分别鉴定为:2-O-(E)-咖啡酰-3-O-(3,5-二甲氧基香豆酰)-α-D-呋喃果糖甙(1),2-O-β-D-呋喃果糖基α-D-异吡喃糖酯(2),甘草甜素(3),4′-羟基-7-O-葡萄糖-2,3-二羟黄酮甙(4),黄豆甙(5),5-葡萄糖芹菜甙(6),7-O-葡萄糖芹菜甙(7),4-O-葡萄糖香豆酸(8),葡萄糖咖啡酸(9),3β-赤杨醇(10),薯蓣皂甙3-O-{α-L-鼠李糖吡喃糖基(1→2)-[α-L-阿拉伯呋喃糖基(1→3)]-β-D-葡萄糖吡喃糖}(11)。

A new fructofuranoside, together with ten known compounds were isolated from the EtOH extraction of the aerial part of Helwingia chinensis. Their structures were elucidated to be 2 -O- （ E）-caffeoyl-3- O -（3, 5-dimethoxylcoumaroyl ）- α-D-fructofuranose （1）, 2-O-β-D-fructofuranosyl-a-D-allopyranose （2）, liquiritigenin （3）, 4＇-hydroxy-2, 3-dihydro-flavonone-7-O-β-D-glucoside （4）, daidzin （5）, apigenin 5-O-glucopyranoside （6）, apigenin-7-O-β-D-glucoside （7）, coumarie acid 4-O-β-D-glucopyranoside （8）, glucopyranosylcaffeic acid （9）, 3β-hydroxyglufin-5-ene （10）, diosgenin 3-O-α- L-rhamnopyranosyl （ 1 →2 ）-[ α -L-arabinofuranosyl （ 1 →3 ） ]-β-D-glucopyranoside （ 11 ） by intensive interpretation of spectral data.
