摘要

A new chromone, 2,3,5,7-tetrahydroxychromone (1), along with 13 known compounds, including (+)-syringaresinol (2), (+)-dia-syringaresinol (3), (+)-epi-syringaresinol (4), 5-hydroxymethylfurfural (5), 5-acetoxymethylfurfural (6), 5-methoxyfurfural (7), 5-hydroxymethyl-2-furancarboxylic acid (8), 4-hydroxyacetophenone (9), 2,3-dihydroxyacetophenone (10), 2,4-dihydroxyacetophenone (11), scopoletin (12), isoscopoletin (13), and umbelliferone (14), were isolated from the stems of Vitis amurensis (Vitaceae). The structure of the new chromone derivative was elucidated by chemical and physical evidence.
