见血封喉树叶化学成分研究

Chemical Constituents from the Leaves of Antiaris toxicaria

摘要:

从见血封喉(Antiaris toxicaria (Pers.) Lesch.)树叶中分离得到了6个化合物, 经波谱数据分析，分别鉴定其结构为：(3S,5R,6S,7E,9R)-3,6-dihydroxy-5,6-dihydro-β-ionol (1)、(5R)-4,5-二氢布卢门醇A(2)、槲皮素-3-O-β-D-葡萄糖苷(3)、异鼠李素-3-O-β-D-芸香糖苷(4)、山柰甲黄素-3-O-β-D-葡萄糖苷(5)和环氧松柏醇(6)，以上化合物均为首次从该种植物中分离得到。

Abstract:

Six compounds were isolated from the leaves of Antiaris toxicaria. On the basis of spectral data, they were identified as (3S,5R,6S,7E,9R)-3,6-dihydroxy-5,6-dihydro-β-ionol (1), (5R)-4,5-dihydroblumenol A (2), quercetin-3-O-β-D-glucopyranoside (3), narcissin (4), kaempferide-3-O-β-D-glucopyranosdie (5) and epoxyconiferyl alcohol (6). All the compounds were isolated from Antiaris toxicaria for the first time.
