To study the flavones of the flowers of Paulownia fortunei.
The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis.
The compounds were identified as: 3'-O-methyldiplacol (1), 6-geranyl-3, 3', 5, 7-tetrahydroxy-4'-methoxy flavanone (2), homoeriodictyol (3), 5, 7, 4'-trihydroxy-3'-methoxy flavone (4), 3'-methoxyluteolin-7-O-beta-D-glucoside (5), apigenin-7-O-beta-D-glucoside (6), kaempferol-7-O-beta-D-glucoside (7), quercetin-3-O-beta-D-glucoside (8), kaempferol-3-O-beta-D-glucoside (9), quercetin-7-O-beta-D-glucoside (10), luteolin-7-O-beta-D-glucoside (11).
All these compounds were obtained from the flowers for the first time.
研究泡桐花中的黄酮类化合物。
通过柱色谱法分离其成分，并通过光谱分析阐明其结构。
鉴定出的化合物如下：3'-O-甲基双桐酚（1）、6-香叶基-3,3',5,7-四羟基-4'-甲氧基黄烷酮（2）、高圣草酚（3）、5,7,4'-三羟基-3'-甲氧基黄酮（4）、3'-甲氧基木犀草素-7-O-β-D-葡萄糖苷（5）、芹菜素-7-O-β-D-葡萄糖苷（6）、山柰酚-7-O-β-D-葡萄糖苷（7）、槲皮素-3-O-β-D-葡萄糖苷（8）、山柰酚-3-O-β-D-葡萄糖苷（9）、槲皮素-7-O-β-D-葡萄糖苷（10）、木犀草素-7-O-β-D-葡萄糖苷（11）。
所有这些化合物均首次从泡桐花中获得。
