幌伞枫叶的化学成分研究

Chemical Constituents from Leaves of Heteropanax fragrans

摘要:

为了解幌伞枫(Heteropanax fragrans)的药理活性化学基础,从其叶的乙醇提取物中分离得到8个化合物,经波谱分析分别鉴定为: (7S,8R)-蛇菰脂醛素-4-O-β-D-吡喃葡萄糖苷 (1)、4β,10α-香木兰烷二醇 (2)、原儿茶酸 (3)、3'-甲氧基-槲皮素-3- O-β-D-吡喃葡萄糖苷 (4)、山柰酚-3-O-β-D-吡喃葡萄糖苷 (5)、槲皮素-3-O-β-D-吡喃葡萄糖苷 (6)、槲皮素-3-O-β-D-芸香糖苷 (7)和山柰酚-3-O-β-D-芸香糖苷 (8)。这8个化合物均为首次从幌伞枫中分离得到。

Abstract:

To further investigate the biological chemical constituents of pharmacological effects of folk medicine Heteropanax fragrans (Roxb.) Seem., eight compounds were isolated from the alcohol extract of the leaves. On the basis of spectral data, their structures were identified as: (7S,8R)-balanophonin-4-O-β-D-glucopyranoside (1), 4β,10α-aromadendranediol (2), protocatechuic acid (3), 3′-methoxy-quercetin-3-O-β-d-glucopyranoside (4), kaempferol-3-O-β-D-glucopyranoside (5), quercetin-3-O-β-D-glucopyranoside (6), quercetin-3-O-β-D-rutinoside (7), kaempferol-3-O-β-d-rutinoside (8). All of eight compounds were obtained from this species for the first time.
