制备方法与用途

概述

亚麻籽中含有大量的木质素——开环异落叶松树脂酚（SECO），这种物质以糖苷形式存在，即开环异落叶松树脂酚二葡萄糖苷（SDG）。

用途

作为肠道菌转化木质素的中间产物，开环异落叶松树脂酚在功能食品中添加时更易被人体吸收，对人体更加有益。此外，它还具有较强的抗氧化性、预防乳腺癌、抑制糖尿病及减轻妇女绝经期症状等多种生理活性。

生物活性

SEcoisolariciresinol 从银杉（Abies alba）提取物中分离出来，是一种木脂素，属于苯丙素类。

  Abstract Root extracts from Urtica dioica were separated into several classes of compounds by extraction with organic solvents at different pH values. The phenolic fraction was analysed by GC-MS after trimethylsilylation. This procedure allowed the identification of 18 phenolic compounds as well as the detection of eight lignans.
