Abstract

Lycium intricatum Boiss also called ‘Awsadj’ is a subshrub belonging to the Solanaceae family and producing red berries. In the present work, we report the isolation of a new compound, ((1 R,3aR,7aS)-3a,7-dimethyl-1-((E)-prop-1-en-1-yl)-1,3a,4,7a-tetrahydroisobenzofuran-5(3H)-one (1)). Three known compounds were also isolated for the first time from L. intricatum, and identified as isoscopoletin (2), 3,4,5-trimethoxybenzyl alcohol (3), and (+)-isolariciresinol (4). Compounds 1-4 were isolated from the extract of leaves using chromatographic techniques, and the structure of compound 1 was fully elucidated by NMR, MS and ECD experiments.

摘要

Lycium intricatum Boiss 也称为“Awsadj”，是茄科亚灌木，生产红色浆果。在目前的工作中，我们报告了一种新化合物的分离，((1 R,3aR,7aS)-3a,7-dimethyl-1-((E)-prop-1-en-1-yl)-1, 3a,4,7a-四氢异苯并呋喃-5(3H)-one ( 1 ))。三种已知化合物也是首次从毛茛中分离得到，分别为异东莨菪碱( 2)、3,4,5-三甲氧基苯甲醇( 3 )和(+)-异落叶松树脂醇( 4 )。用色谱技术从叶子的提取物中分离出化合物1-4 ，化合物1的结构 通过 NMR、MS 和 ECD 实验充分阐明。
