摘要
从木本藤(Gymnema sylvestre, Retz)叶中分离得到7种已知木脂素，分别为:陆甲苷A(1)、(+)-丁香脂醇(2)、(+)-中脂醇(3)、(+)-松脂醇(4)、(+)-松脂醇-6-基β- d -葡萄糖苷(5)、(-)-松脂醇3α- o -β- d -葡萄糖苷(6)和(-)-松脂醇(7)。R.Br。Schult交货。根据光谱证据并与文献报道的结构进行了比较，确定了它们的结构。所有化合物均为首次从该植物中分离得到。
Seven known lignans, tortoside A (1), (+)-syringaresinol (2), (+)-medioresinol (3), (+)-pinoresinol (4), (+)-lyoniresin-6-yl β-D-glucopyranoside (5), (-)-lyoniresinol 3α-O-β-D-glucopyranoside (6), and (-)-lyoniresinol (7) were isolated from the leaves of Gymnema sylvestre (Retz.) R.Br. ex Schult. Their structures were identified on the basis of spectroscopic evidence and in comparison with those reported in the literature. All compounds were reported from G. sylvestre for the first time.
