| 中文摘要 |
自山黃麻（Trema orientalis）的莖部共得到八個化合物，包括（–）-ampelopsin F （1）、（–）-epicatechin （2）、（+）-catechin （3）、（+）-syringaresinol （4）、N-（trans-p-coumaroyl）tyramine（5）、N-（trans-p-coumaroyl）octopamin （6）、trans-4-hydroxy-cinnamic acid （7）及3,5-dimethoxy-4-hydroxyphenyl-1-O-β-D-glucoside （8）。這些化合物之構造皆經質譜及核磁共振光譜的解析而確認。Eight compounds, (–)-ampelopsin F (1), (–)-epicatechin (2), (+)-catechin (3), (+)-syringaresinol (4), N-(trans-p-coumaroyl)tyramine (5), N-(trans-p-coumaroyl)octopamin (6), trans-4-hydroxycinnamic acid (7) and 3,5-dimethoxy-4-hydroxyphenyl-1-O-β-D-glucoside (8) were isolated from the stem of Trema orientalis. Their structures were determined by spectral methods and/or comparison with those in the literature. |
