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.
