A new neolignan glycoside, (7R,8R)-7,8-dihydro-9'-hydroxyl-3'-methoxyl- 8-hydroxymethyl-7-(4-hydroxy-3-methoxyphenyl)-1'-benzofuranpropanol 9'-O-beta-D- glucopyranoside (1) was isolated from the leaves of Acer truncatum along with (7R,8R)-7,8-dihydro-9'-hydroxyl-3'-methoxyl-8-hydroxymethyl-7-(4-O-alpha-L-rhamno- pyranosyloxy-3-methoxyphenyl)-1'-benzofuranpropanol (2), schizandriside (3), lyoniresinol (4), berchemol (5), (-)-pinoresinol-4-O-beta-D-glucopyranoside (6), hecogenin (7), chlorogenic acid (8) and neochlorogenic acid (9). Their structures were elucidated on the basis of extensive spectroscopic data. The absolute configuration of compounds 1 was established by its CD spectrum. The antibacterial activities of compounds 1-7 were evaluated.
从元宝枫叶中分离出一种新的新木脂素糖苷，即(7R,8R)-7,8-二氢-9'-羟基-3'-甲氧基-8-羟甲基-7-(4-羟基-3-甲氧基苯基)-1'-苯并呋喃丙醇9'-O-β-D-吡喃葡萄糖苷(1)，同时还分离出(7R,8R)-7,8-二氢-9'-羟基-3'-甲氧基-8-羟甲基-7-(4-O-α-L-鼠李糖基氧基-3-甲氧基苯基)-1'-苯并呋喃丙醇(2)、五味子苷(3)、南烛木树脂醇(4)、小檗醇(5)、(-)-松脂醇-4-O-β-D-吡喃葡萄糖苷(6)、海柯皂苷元(7)、绿原酸(8)和新绿原酸(9)。根据大量光谱数据阐明了它们的结构。化合物1的绝对构型通过其圆二色谱确定。评估了化合物1-7的抗菌活性。
